World War I

By: History.com Editors

Updated: May 10, 2024 | Original: October 29, 2009

World War I, also known as the Great War, started in 1914 after the assassination of Archduke Franz Ferdinand of Austria. His murder catapulted into a war across Europe that lasted until 1918. During the four-year conflict, Germany, Austria-Hungary, Bulgaria and the Ottoman Empire (the Central Powers) fought against Great Britain, France, Russia, Italy, Romania, Canada, Japan and the United States (the Allied Powers). Thanks to new military technologies and the horrors of trench warfare, World War I saw unprecedented levels of carnage and destruction. By the time the war was over and the Allied Powers had won, more than 16 million people—soldiers and civilians alike—were dead.

Archduke Franz Ferdinand

Tensions had been brewing throughout Europe—especially in the troubled Balkan region of southeast Europe—for years before World War I actually broke out.

A number of alliances involving European powers, the Ottoman Empire , Russia and other parties had existed for years, but political instability in the Balkans (particularly Bosnia, Serbia and Herzegovina) threatened to destroy these agreements.

The spark that ignited World War I was struck in Sarajevo, Bosnia, where Archduke Franz Ferdinand —heir to the Austro-Hungarian Empire—was shot to death along with his wife, Sophie, by the Serbian nationalist Gavrilo Princip on June 28, 1914. Princip and other nationalists were struggling to end Austro-Hungarian rule over Bosnia and Herzegovina.

The assassination of Franz Ferdinand set off a rapidly escalating chain of events: Austria-Hungary , like many countries around the world, blamed the Serbian government for the attack and hoped to use the incident as justification for settling the question of Serbian nationalism once and for all.

Kaiser Wilhelm II

Because mighty Russia supported Serbia, Austria-Hungary waited to declare war until its leaders received assurance from German leader Kaiser Wilhelm II that Germany would support their cause. Austro-Hungarian leaders feared that a Russian intervention would involve Russia’s ally, France, and possibly Great Britain as well.

On July 5, Kaiser Wilhelm secretly pledged his support, giving Austria-Hungary a so-called carte blanche, or “blank check” assurance of Germany’s backing in the case of war. The Dual Monarchy of Austria-Hungary then sent an ultimatum to Serbia, with such harsh terms as to make it almost impossible to accept.

World War I Begins

Convinced that Austria-Hungary was readying for war, the Serbian government ordered the Serbian army to mobilize and appealed to Russia for assistance. On July 28, Austria-Hungary declared war on Serbia, and the tenuous peace between Europe’s great powers quickly collapsed.

Within a week, Russia, Belgium, France, Great Britain and Serbia had lined up against Austria-Hungary and Germany, and World War I had begun.

The Western Front

According to an aggressive military strategy known as the Schlieffen Plan (named for its mastermind, German Field Marshal Alfred von Schlieffen ), Germany began fighting World War I on two fronts, invading France through neutral Belgium in the west and confronting Russia in the east.

On August 4, 1914, German troops crossed the border into Belgium. In the first battle of World War I, the Germans assaulted the heavily fortified city of Liege , using the most powerful weapons in their arsenal—enormous siege cannons—to capture the city by August 15. The Germans left death and destruction in their wake as they advanced through Belgium toward France, shooting civilians and executing a Belgian priest they had accused of inciting civilian resistance. 

First Battle of the Marne

In the First Battle of the Marne , fought from September 6-9, 1914, French and British forces confronted the invading German army, which had by then penetrated deep into northeastern France, within 30 miles of Paris. The Allied troops checked the German advance and mounted a successful counterattack, driving the Germans back to the north of the Aisne River.

The defeat meant the end of German plans for a quick victory in France. Both sides dug into trenches , and the Western Front was the setting for a hellish war of attrition that would last more than three years.

Particularly long and costly battles in this campaign were fought at Verdun (February-December 1916) and the Battle of the Somme (July-November 1916). German and French troops suffered close to a million casualties in the Battle of Verdun alone.

World War I Books and Art

The bloodshed on the battlefields of the Western Front, and the difficulties its soldiers had for years after the fighting had ended, inspired such works of art as “ All Quiet on the Western Front ” by Erich Maria Remarque and “ In Flanders Fields ” by Canadian doctor Lieutenant-Colonel John McCrae . In the latter poem, McCrae writes from the perspective of the fallen soldiers:

Published in 1915, the poem inspired the use of the poppy as a symbol of remembrance.

Visual artists like Otto Dix of Germany and British painters Wyndham Lewis, Paul Nash and David Bomberg used their firsthand experience as soldiers in World War I to create their art, capturing the anguish of trench warfare and exploring the themes of technology, violence and landscapes decimated by war.

The Eastern Front

On the Eastern Front of World War I, Russian forces invaded the German-held regions of East Prussia and Poland but were stopped short by German and Austrian forces at the Battle of Tannenberg in late August 1914.

Despite that victory, Russia’s assault forced Germany to move two corps from the Western Front to the Eastern, contributing to the German loss in the Battle of the Marne.

Combined with the fierce Allied resistance in France, the ability of Russia’s huge war machine to mobilize relatively quickly in the east ensured a longer, more grueling conflict instead of the quick victory Germany had hoped to win under the Schlieffen Plan .

Russian Revolution

From 1914 to 1916, Russia’s army mounted several offensives on World War I’s Eastern Front but was unable to break through German lines.

Defeat on the battlefield, combined with economic instability and the scarcity of food and other essentials, led to mounting discontent among the bulk of Russia’s population, especially the poverty-stricken workers and peasants. This increased hostility was directed toward the imperial regime of Czar Nicholas II and his unpopular German-born wife, Alexandra.

Russia’s simmering instability exploded in the Russian Revolution of 1917, spearheaded by Vladimir Lenin and the Bolsheviks , which ended czarist rule and brought a halt to Russian participation in World War I.

Russia reached an armistice with the Central Powers in early December 1917, freeing German troops to face the remaining Allies on the Western Front.

America Enters World War I

At the outbreak of fighting in 1914, the United States remained on the sidelines of World War I, adopting the policy of neutrality favored by President Woodrow Wilson while continuing to engage in commerce and shipping with European countries on both sides of the conflict.

Neutrality, however, it was increasingly difficult to maintain in the face of Germany’s unchecked submarine aggression against neutral ships, including those carrying passengers. In 1915, Germany declared the waters surrounding the British Isles to be a war zone, and German U-boats sunk several commercial and passenger vessels, including some U.S. ships.

Widespread protest over the sinking by U-boat of the British ocean liner Lusitania —traveling from New York to Liverpool, England with hundreds of American passengers onboard—in May 1915 helped turn the tide of American public opinion against Germany. In February 1917, Congress passed a $250 million arms appropriations bill intended to make the United States ready for war.

Germany sunk four more U.S. merchant ships the following month, and on April 2 Woodrow Wilson appeared before Congress and called for a declaration of war against Germany.

Gallipoli Campaign

With World War I having effectively settled into a stalemate in Europe, the Allies attempted to score a victory against the Ottoman Empire, which entered the conflict on the side of the Central Powers in late 1914.

After a failed attack on the Dardanelles (the strait linking the Sea of Marmara with the Aegean Sea), Allied forces led by Britain launched a large-scale land invasion of the Gallipoli Peninsula in April 1915. The invasion also proved a dismal failure, and in January 1916 Allied forces staged a full retreat from the shores of the peninsula after suffering 250,000 casualties.

Did you know? The young Winston Churchill, then first lord of the British Admiralty, resigned his command after the failed Gallipoli campaign in 1916, accepting a commission with an infantry battalion in France.

British-led forces also combated the Ottoman Turks in Egypt and Mesopotamia , while in northern Italy, Austrian and Italian troops faced off in a series of 12 battles along the Isonzo River, located at the border between the two nations.

Battle of the Isonzo

The First Battle of the Isonzo took place in the late spring of 1915, soon after Italy’s entrance into the war on the Allied side. In the Twelfth Battle of the Isonzo, also known as the Battle of Caporetto (October 1917), German reinforcements helped Austria-Hungary win a decisive victory.

After Caporetto, Italy’s allies jumped in to offer increased assistance. British and French—and later, American—troops arrived in the region, and the Allies began to take back the Italian Front.

World War I at Sea

In the years before World War I, the superiority of Britain’s Royal Navy was unchallenged by any other nation’s fleet, but the Imperial German Navy had made substantial strides in closing the gap between the two naval powers. Germany’s strength on the high seas was also aided by its lethal fleet of U-boat submarines.

After the Battle of Dogger Bank in January 1915, in which the British mounted a surprise attack on German ships in the North Sea, the German navy chose not to confront Britain’s mighty Royal Navy in a major battle for more than a year, preferring to rest the bulk of its naval strategy on its U-boats.

The biggest naval engagement of World War I, the Battle of Jutland (May 1916) left British naval superiority on the North Sea intact, and Germany would make no further attempts to break an Allied naval blockade for the remainder of the war.

World War I Planes

World War I was the first major conflict to harness the power of planes. Though not as impactful as the British Royal Navy or Germany’s U-boats, the use of planes in World War I presaged their later, pivotal role in military conflicts around the globe.

At the dawn of World War I, aviation was a relatively new field; the Wright brothers took their first sustained flight just eleven years before, in 1903. Aircraft were initially used primarily for reconnaissance missions. During the First Battle of the Marne, information passed from pilots allowed the allies to exploit weak spots in the German lines, helping the Allies to push Germany out of France.

The first machine guns were successfully mounted on planes in June of 1912 in the United States, but were imperfect; if timed incorrectly, a bullet could easily destroy the propeller of the plane it came from. The Morane-Saulnier L, a French plane, provided a solution: The propeller was armored with deflector wedges that prevented bullets from hitting it. The Morane-Saulnier Type L was used by the French, the British Royal Flying Corps (part of the Army), the British Royal Navy Air Service and the Imperial Russian Air Service. The British Bristol Type 22 was another popular model used for both reconnaissance work and as a fighter plane.

Dutch inventor Anthony Fokker improved upon the French deflector system in 1915. His “interrupter” synchronized the firing of the guns with the plane’s propeller to avoid collisions. Though his most popular plane during WWI was the single-seat Fokker Eindecker, Fokker created over 40 kinds of airplanes for the Germans.

The Allies debuted the Handley-Page HP O/400, the first two-engine bomber, in 1915. As aerial technology progressed, long-range heavy bombers like Germany’s Gotha G.V. (first introduced in 1917) were used to strike cities like London. Their speed and maneuverability proved to be far deadlier than Germany’s earlier Zeppelin raids.

By the war’s end, the Allies were producing five times more aircraft than the Germans. On April 1, 1918, the British created the Royal Air Force, or RAF, the first air force to be a separate military branch independent from the navy or army. 

Second Battle of the Marne

With Germany able to build up its strength on the Western Front after the armistice with Russia, Allied troops struggled to hold off another German offensive until promised reinforcements from the United States were able to arrive.

On July 15, 1918, German troops launched what would become the last German offensive of the war, attacking French forces (joined by 85,000 American troops as well as some of the British Expeditionary Force) in the Second Battle of the Marne . The Allies successfully pushed back the German offensive and launched their own counteroffensive just three days later.

After suffering massive casualties, Germany was forced to call off a planned offensive further north, in the Flanders region stretching between France and Belgium, which was envisioned as Germany’s best hope of victory.

The Second Battle of the Marne turned the tide of war decisively towards the Allies, who were able to regain much of France and Belgium in the months that followed.

The Harlem Hellfighters and Other All-Black Regiments

By the time World War I began, there were four all-Black regiments in the U.S. military: the 24th and 25th Infantry and the 9th and 10th Cavalry. All four regiments comprised of celebrated soldiers who fought in the Spanish-American War and American-Indian Wars , and served in the American territories. But they were not deployed for overseas combat in World War I. 

Blacks serving alongside white soldiers on the front lines in Europe was inconceivable to the U.S. military. Instead, the first African American troops sent overseas served in segregated labor battalions, restricted to menial roles in the Army and Navy, and shutout of the Marines, entirely. Their duties mostly included unloading ships, transporting materials from train depots, bases and ports, digging trenches, cooking and maintenance, removing barbed wire and inoperable equipment, and burying soldiers.

Facing criticism from the Black community and civil rights organizations for its quotas and treatment of African American soldiers in the war effort, the military formed two Black combat units in 1917, the 92nd and 93rd Divisions . Trained separately and inadequately in the United States, the divisions fared differently in the war. The 92nd faced criticism for their performance in the Meuse-Argonne campaign in September 1918. The 93rd Division, however, had more success. 

With dwindling armies, France asked America for reinforcements, and General John Pershing , commander of the American Expeditionary Forces, sent regiments in the 93 Division to over, since France had experience fighting alongside Black soldiers from their Senegalese French Colonial army. The 93 Division’s 369 regiment, nicknamed the Harlem Hellfighters , fought so gallantly, with a total of 191 days on the front lines, longer than any AEF regiment, that France awarded them the Croix de Guerre for their heroism. More than 350,000 African American soldiers would serve in World War I in various capacities.

Toward Armistice

By the fall of 1918, the Central Powers were unraveling on all fronts.

Despite the Turkish victory at Gallipoli, later defeats by invading forces and an Arab revolt that destroyed the Ottoman economy and devastated its land, and the Turks signed a treaty with the Allies in late October 1918.

Austria-Hungary, dissolving from within due to growing nationalist movements among its diverse population, reached an armistice on November 4. Facing dwindling resources on the battlefield, discontent on the homefront and the surrender of its allies, Germany was finally forced to seek an armistice on November 11, 1918, ending World War I.

Treaty of Versailles

At the Paris Peace Conference in 1919, Allied leaders stated their desire to build a post-war world that would safeguard itself against future conflicts of such a devastating scale.

Some hopeful participants had even begun calling World War I “the War to End All Wars.” But the Treaty of Versailles , signed on June 28, 1919, would not achieve that lofty goal.

Saddled with war guilt, heavy reparations and denied entrance into the League of Nations , Germany felt tricked into signing the treaty, having believed any peace would be a “peace without victory,” as put forward by President Wilson in his famous Fourteen Points speech of January 1918.

As the years passed, hatred of the Versailles treaty and its authors settled into a smoldering resentment in Germany that would, two decades later, be counted among the causes of World War II .

World War I Casualties

World War I took the lives of more than 9 million soldiers; 21 million more were wounded. Civilian casualties numbered close to 10 million. The two nations most affected were Germany and France, each of which sent some 80 percent of their male populations between the ages of 15 and 49 into battle.

The political disruption surrounding World War I also contributed to the fall of four venerable imperial dynasties: Germany, Austria-Hungary, Russia and Turkey.

Legacy of World War I

World War I brought about massive social upheaval, as millions of women entered the workforce to replace men who went to war and those who never came back. The first global war also helped to spread one of the world’s deadliest global pandemics, the Spanish flu epidemic of 1918, which killed an estimated 20 to 50 million people.

World War I has also been referred to as “the first modern war.” Many of the technologies now associated with military conflict—machine guns, tanks , aerial combat and radio communications—were introduced on a massive scale during World War I.

The severe effects that chemical weapons such as mustard gas and phosgene had on soldiers and civilians during World War I galvanized public and military attitudes against their continued use. The Geneva Convention agreements, signed in 1925, restricted the use of chemical and biological agents in warfare and remain in effect today.

What Caused the First World War?

World war why, one shot: the assassination of archduke franz ferdinand, deeper trends: help me help you help me, accidental war: missed the memo, hit the target.

• Yes, these terms can get confusing. Nationalism was introduced to you as the idea that a state should govern itself, and not have some empire as its boss. But at some point, that feeling that you should get to govern yourself can turn into the idea that you are better than other nations, and becomes a kind of extreme patriotism. We call that nationalism as well. As we will see, nationalism is a pretty flexible thing, and it can be used for lots of different purposes.

World War I was a major conflict fought in Europe and around the world between July 28, 1914, and November 11, 1918. Nations from across all non-polar continents were involved , although Russia, Britain, France, Germany, and Austria-Hungary dominated. Much of the war was characterized by stagnant trench warfare and massive loss of life in failed attacks; over eight million people were killed in battle.

The war was fought by two main power blocks: the Entente Powers , or 'Allies,' comprised of Russia, France, Britain (and later the U.S.), and their allies on one side and the Central Powers of Germany, Austro-Hungary, Turkey, and their allies on the other. Italy later joined the Entente. Many other countries played smaller parts on both sides.

Origins of World War I

To understand the origins , it is important to understand how politics at the time. European politics in the early twentieth century were a dichotomy: many politicians thought war had been banished by progress while others, influenced partly by a fierce arms race, felt war was inevitable. In Germany, this belief went further: the war should happen sooner rather than later, while they still (as they believed) had an advantage over their perceived major enemy, Russia. As Russia and France were allied, Germany feared an attack from both sides. To mitigate this threat, the Germans developed the Schlieffen Plan , a swift looping attack on France designed to knock it out early, allowing for concentration on Russia.

Rising tensions culminated on June 28th, 1914 with the assassination of  Austro-Hungarian Archduke Franz Ferdinand  by a Serbian activist, an ally of Russia. Austro-Hungary asked for German support and was promised a 'blank cheque'; they declared war on Serbia on July 28th. What followed was a sort of domino effect as more and more nations joined the fight . Russia mobilized to support Serbia, so Germany declared war on Russia; France then declared war on Germany. As German troops swung through Belgium into France days later, Britain declared war on Germany too. Declarations continued until much of Europe was at war with each other. There was widespread public support.

After the swift German invasion of France was stopped at the Marne, 'the race to the sea' followed as each side tried to outflank each other ever closer to the English Channel. This left the entire Western Front divided by over 400 miles of trenches, around which the war stagnated. Despite massive battles like Ypres , little progress was made and a battle of attrition emerged, caused partly by German intentions to 'bleed the French dry' at Verdun and Britain's attempts on the Somme . There was more movement on the Eastern Front with some major victories, but there was nothing decisive and the war carried on with high casualties.

Attempts to find another route into their enemy’s territory led to the failed Allied invasion of Gallipoli, where Allied forces held a beachhead but were halted by fierce Turkish resistance. There was also conflict on the Italian front, the Balkans, the Middle East, and smaller struggles in colonial holdings where the warring powers bordered each other.

Although the build-up to war had included a naval arms race between Britain and Germany, the only large naval engagement of the conflict was the Battle of Jutland, where both sides claimed victory. Instead, the defining struggle involved submarines and the German decision to pursue Unrestricted Submarine Warfare (USW). This policy allowed submarines to attack any target they found, including those belonging to the 'neutral' United States, which caused the latter to enter the war in 1917 on behalf of the Allies, supplying much-needed manpower.

Despite Austria-Hungary becoming little more than a German satellite, the Eastern Front was the first to be resolved, the war causing massive political and military instability in Russia, leading to the Revolutions of 1917 , the emergence of socialist government and surrender on December 15. Efforts by the Germans to redirect manpower and take the offensive in the west failed and, on November 11, 1918 (at 11:00 am), faced with allied successes, massive disruption at home and the impending arrival of vast US manpower, Germany signed an Armistice, the last Central power to do so.

Each of the defeated nations signed a treaty with the Allies, most significantly the Treaty of Versailles which was signed with Germany, and which has been blamed for causing further disruption ever since. There was devastation across Europe: 59 million troops had been mobilized, over 8 million died and over 29 million were injured. Huge quantities of capital had been passed to the now emergent United States and the culture of every European nation was deeply affected and the struggle became known as The Great War or The War to End All Wars.

World War I was the first to make major use of machine guns, which soon showed their defensive qualities. It was also the first to see poison gas used on the battlefields, a weapon which both sides made use of, and the first to see tanks, which were initially developed by the allies and later used to great success. The use of aircraft evolved from simply reconnaissance to a whole new form of aerial warfare.

Thanks partly to a generation of war poets who recorded the horrors of the war and a generation of historians who castigated the Allied high command for their decisions and ‘waste of life’ (Allied soldiers being the 'Lions led by Donkeys'), the war was generally viewed as a pointless tragedy. However, later generations of historians have found mileage in revising this view. While the Donkeys have always been ripe for recalibration, and careers built on provocation have always found material (such as Niall Ferguson's The Pity of War ), the centenary commemorations found historiography split between a phalanx wishing to create a new martial pride and sideline the worst of the war to create an image of a conflict well worth fighting and then truly won by the allies, and those who wished to stress the alarming and pointless imperial game millions of people died for. The war remains highly controversial and as subject to attack and defense as the newspapers of the day.

World War I

An introduction to world war i.

World War I was a defining event in world history. In August 1914 the nations of Europe tumbled into a war that would ravage their continent and shape the course of the next century. Mankind had known wars of destruction and folly before – but none approached the scale and barbarity of World War I. For four years Europe was paralysed and ravaged by the horrors of industrial weaponry, militarism and total war. The war lacerated the continent, creating two war fronts spanning hundreds of miles each. Millions of fit, healthy men were placed in uniform and marched into the killing fields of France, Belgium and the Eastern Front. Fighting also spread beyond the war’s European crucible, breaking out in the Dardanelles, the Middle East and the distant colonies of Africa and Asia. On the seas, cargo ships and passenger vessels were threatened by blockades and destroyed by submarines, a revolutionary form of naval warfare. World War I was also fought high in the sky, by flying machines that had not been conceived just two decades before. Conflict on this scale required ‘total war’: a war supplied and perpetuated by the coordinated efforts of governments, economies and entire societies. As Winston Churchill later said, “all the horrors of all the ages were brought together; not only armies but whole populations were thrust into the midst of them”.

Human error and misjudgement were tragic features of the conflict. The historian A. J. P. Taylor once wrote that blunders shape history more than wickedness; he might have said this with World War I in mind. Many elements of the war, particularly its causes, now seem avoidable, if not absurd. The war emerged not from a pressing dispute or territorial claim, but a poisonous mix of nationalism, xenophobia, paranoia, militaristic bravado, imperialist ambition, misunderstanding and folly. None of this caught anyone by surprise: these attitudes had prickled European relations since the late 19th century. Looking back a century later, it seems ridiculous that modern statesmen and intellectuals could be so blind to these dangers. But blind they were – and the consequences for those they ruled would prove catastrophic. Military and strategic incompetence and short-sightedness also played their part. For years Europe’s career generals had predicted, even expected an industrial war, yet they failed to anticipate what form it might take. Their battle plans were largely based on outdated modes of warfare, some dating back to the days of Napoleon. Strategists clung to the idea that any defensive line could be penetrated, if enough men, horses and bayonets were thrown against it. Germany’s Schlieffen Plan – an ambitious offensive and flanking attack, designed to knock the French out of the war before Russia could fully mobilise – fell short of its ultimate objectives. By late 1914 the Schlieffen assault, slowed by French and Belgian resistance, had run out of steam. As millions of troops poured into northern France, the war froze into stalemate. Armies dug into the ground so that they could hold it; the value of the offensive push was negated by the machine gun and the trench. In just a few weeks of war, the best plans of Europe’s military elite had been exposed as as balderdash.

“The First World War was a tragic and unnecessary conflict. Unnecessary because the train of events that led to its outbreak might have been broken at any point during the five weeks of crisis that preceded the first clash of arms, had prudence or common goodwill found a voice; tragic because the consequences of the first clash ended the lives of ten million human beings, tortured the emotional lives of millions more, destroyed the benevolent and optimistic culture of the European continent and left, when the guns at last fell silent four years later, a legacy of political rancour and racial hatred so intense that no explanation of the causes of the Second World War can stand without reference to those roots… Over half those who died in the Great War were lost as corpses to the wilderness of the battlefield.” John Keegan, historian

The human cost of World War I was staggering. At least 12 million people were killed on the battlefield, many of them utterly obliterated. Millions more were left wounded and disfigured, limbless, crippled or seriously injured. The weapons of industrial warfare, particularly artillery and machine gun fire, chewed through young men as a farm machine threshes through hay. Around ten per cent of all French men under the age of 45 were killed or reported missing. Russia lost so many soldiers it was unable to tally them accurately to the nearest million. Sparsely populated Australia sent more than 415,000 volunteer servicemen – almost ten per cent of its entire population – to the battlefields of Gallipoli, the Middle East and the Western Front. Of this number around one Australian serviceman in every seven would die. Very few of the wartime generation escaped physical suffering, psychological scarring or bereavement. Almost every civilian had a connection with casualties of war.

In some respects World War I was a confrontation between the old and the new, a transforming event that shattered traditional ideas and beliefs. The war certainly changed the political, social and cultural landscape of Europe. Its most visible fatalities were Europe’s old monarchies, which did not survive the maelstrom they themselves had unleashed. In Germany, the Hohenzollern monarchy was toppled from within by its starving people, the kaiser abdicating and taking refuge in Holland. In Russia, the Romanov tsar suffered an even worse fate, overthrown by his own people and later murdered. In Austria-Hungary, neither the Hapsburg royal house or its patchwork empire survived the war. While the removal of these old dynasties was celebrated by many as a step into modernity, their departure left power vacuums and new regimes that proved no better – and in the case of Russia was considerably worse. The war also fanned the flames of political and social reform. Left wing politics flourished as Europeans sought new answers and explanations. The melancholy post war years also gave rise to modernist artistic movements, that sought to capture the despair of the people.

The final battleground of World War I was in the meeting rooms of Paris in 1919. There the statesmen of Europe set about rebuilding their continent and crafting a peace they hoped would last for generations. History reveals it as a battle they lost. The worst decisions are often made in anger – and the ‘big men’ of Paris placed a higher store on blame and retribution than on reconciliation and reconstruction. Germany, excluded from the peace talks, was forced to admit absolute responsibility for starting the war. She was stripped of her industries, left with a skeleton military and slapped with crippling reparations payments. Already devastated by years of war and starvation, the German state soon became an economic basket case, leaving it open to the perils of political extremism. Thinking themselves betrayed and unjustly treated, Germany’s ex-soldiers, militarists and bigots embraced an even more intense and embittered nationalism. The Austro-Hungarian empire was torn apart, its land and people handed to existing nations or used to create new ones. The United States also contributed to the failure of post-war reconstruction. Washington’s refusal to accept membership of the League of Nations, a multi-national body intended to resolve crisis and prevent war, undermined this body before it was even formed.

Perhaps it comes as no surprise, but the 2017 box office hit Wonder Woman took a few creative liberties in its depiction of World War I. For instance, the film portrayed Ares, the god of war, as the evil mastermind behind the conflict. In reality, it was not the gods who pushed humanity toward conflict. World War I was caused by the actions of ordinary people and political leaders. However, World War I was so violent, costly, and traumatic that it is tempting to blame an all-powerful deity bent on humanity’s destruction.

A Short History of World War I

More than twenty countries that controlled territory on six continents would declare war between 1914 and 1918, making World War I (also known as the Great War) the first truly global conflict. On one side, Britain, France, and Russia formed the Triple Entente (also known as the Allied powers or, simply, the Allies). On the other side, Austria-Hungary, Germany, and Italy made up the Triple Alliance (also known as the Central powers). Those alliances, however, were hardly static, and during the war Italy would change sides; the United States, Japan, and many other nations would join the Allied powers; the Ottoman Empire and Bulgaria would join the Central powers; and Russia would withdraw altogether due to revolution back home.

By the war’s end in 1918, the Allied powers emerged victorious. However, both sides were left reeling from the scale of the violence. New technologies like chemical gas and long-range artillery drove conflict to cruel new heights. Nine million soldiers died while the civilian death toll likely exceeded ten million. Infectious diseases also ran rampant, fighting leveled infrastructure, and the financial toll of the war was immense. Following the conflict, most of the European continent was left in economic disarray.

In trying to make sense of this death and destruction, one obvious question stands out: Why did World War I break out in what had been a mostly peaceful and prosperous continent? 

How did World War I start?

Experts continue to fiercely debate this question. Yes, the 1914 assassination of Archduke Franz Ferdinand, heir to the throne of Austria-Hungary, triggered a series of declarations of war. However many scholars argue that several other factors had been creating the conditions for conflict in Europe for decades prior. As the military historian Liddell Hart wrote, “Fifty years were spent in the process of making Europe explosive. Five days were enough to detonate it.”

This resource explores the factors that led to the outbreak of World War I and how the conflict reshaped society.

Origins of World War I

To understand the origins of World War I, let’s first go back to the early 1800s. 

For centuries, a competing patchwork of European empires and kingdoms had waged near-constant war with each other. These conflicts were generally fought over land, colonies, religion, resources, and dynastic rivalries. As a result, the borders within the continent shifted frequently.

However, after the defeat of French Emperor Napoleon Bonaparte, who had conquered most of Europe, representatives from several European powers were eager to end the cycle of war. In 1814 and 1815, these representatives met in Vienna to establish a framework for peace.. What emerged was a series of agreements and understandings that ushered in an unusual period of relative stability for the continent. The resulting diplomatic system, known as the Concert of Europe, sought to preserve peace by supporting existing dynasties over revolutionary movements.

With peace at home, Europe enjoyed a century of immense progress and global influence. Technological innovations—like the development of machine production, steel, electricity, and modern chemistry—enriched the continent. Meanwhile, improvements in shipping, railroads, and weapons allowed countries to project their power farther abroad. As a result, Europe’s strongest empires—namely, Belgium, Britain, France, the Netherlands, Portugal, and, later, Germany, Italy, and Russia— controlled much of the world throughout the nineteenth century.

However, this period of European peace and prosperity would not last forever. Many historians believe things began to unravel in the mid-1800s. The various regional conflicts and wars to unify the countries of Germany and Italy reintroduced costly warfare to the continent. But, unequivocally, Europe’s century of stability had come to a cataclysmic end with World War I.

Let’s explore three factors that brought about this great unraveling.

Three Causes of World War I

The rise of germany.

Following the Napoleonic Wars, Europe experienced a rough balance of power on the continent. In other words, the region’s strongest countries typically avoided massive conflicts with each other. The odds of conflict were mitigated because Europe’s largest powers were fairly equal in strength. This meant that the costs of going to war would almost certainly outweigh any expected benefits.

Initially, the strength of Austria, Britain, and Russia preserved peace and order. Later, Britain and Prussia (which would become part of Germany in 1871) maintained this balance as the continent’s strongest countries. The two nations both had large populations, towering economies, and robust militaries.

However, power dynamics shifted in the latter half of the nineteenth century.

Britain—the world’s largest empire and the biggest naval and economic power—saw its relative strength begin to fade in the mid- to late-1800s. For generations, Britain had enjoyed global primacy through its strong trade ties, unparalleled navy, and sprawling empire. Britain's imperial power provided access to natural resources and markets around the world. However, the costs of maintaining such a vast, globe-spanning empire began to mount. Additionally, by the end of the nineteenth century, rapidly industrializing countries like the United States and Germany began to outcompete Britain. As a result, Britain’s technological and manufacturing edge over the rest of the world faded.

Germany only emerged as an independent country in 1871 when Prussian leader Otto von Bismarck unified the nation. Prior to unification, Germany had been thirty-nine independent states—made up of a group of people fairly unified in language and culture, though not religion—into a single political unit. This new, united Germany would soon become exceedingly wealthy through industrialization . The country quickly began to showcase its power on the global stage through the acquisition of colonies in Africa.

Although Bismarck worked to preserve peace on the continent by balancing among the other powers, later leaders began to assert German dominance. Notably, historians describe Kaiser Wilhelm II as insecure and arrogant. Wilhelm possessed  unbridled ambition to claim Germany’s “place in the sun.” However, his desire to improve Germany’s international standing ultimately translated into recklessness. For example, he abandoned the Reinsurance Treaty with Russia in 1890, which led to Russia becoming friendly with France—an old enemy to Germany—and then with Britain.

Wilhelm spoke openly—and belligerently—about his desire for German economic and military supremacy and endeavored to make this vision a reality. In particular, he invested heavily in military spending. Wilhelm hoped to build a navy that could challenge Britain’s globally renowned fleet. This rapid militarization ignited an arms race on the continent, which unsettled Europe’s balance of power.

Nationalism

Nationalism is a powerful force that unites people based on ethnic, linguistic, geographic, or other shared characteristics. In certain contexts, it can serve as a basis of unity, inclusion, and social cohesion for a country. But when taken to extremes, nationalism can fuel violence , division, and global disorder.

In the lead-up to World War I, nationalism fueled intense competition in Europe. The continent’s most powerful countries frequently tried to best each other through their empires, militaries, and technological innovations. Meanwhile, governments, the new mass print media, and schools and universities reinforced messages of each country’s superiority.

With memories of the Napoleonic wars long since faded, countries viewed war as a quick and easy way through which to achieve glory. In fact, some Europeans celebrated the arrival of World War I. Parades and cheering spectators sent off their soldiers to the front lines. Young men rushed to recruiting offices eager not to miss the opportunity to serve. Most people believed that “the boys will be home by Christmas.” Few imagined that the war would drag on for four years in such horrific fashion. 

Nationalism unified countries like Britain, France, and Germany—albeit to dangerous extremes. However,the same force also pulled other European empires apart. In particular, Austria-Hungary, the Ottoman Empire, and Russia struggled to promote a cohesive national identity. Given their populations’ vast internal differences along ethnic, cultural, linguistic, and religious lines, these once-great European empires began to fracture.

In fact, the first shot of World War I—the assassination of Archduke Franz Ferdinand of Austria—came at the fault lines of one of those multiethnic empires. Ferdinand’s assassins executed their attack in the name of Slavic nationalism.

Alliance Networks

The assassination of Franz Ferdinand could have remained a small, localized affair. After all, the attack did not directly affect the continent’s greatest forces such as Britain, France, Germany, or even Russia. Rather, it involved two lesser powers: Austria-Hungary and Serbia.

However, European leaders had spent years prior to the assassination constructing a network of alliances. These agreements were built on the promise of collective security, or the idea that an attack on one country would be treated as an attack against the entire alliance.

In theory, those alliances were intended to serve as a deterrent to conflict; a stronger country would be less inclined to attack a weaker one if the latter had the support of a powerful ally. In reality, the alliance networks had the opposite effect. The complex alliance network in Europe expanded local issues into a continent-spanning crisis. Behind Austria-Hungary stood Germany, behind Serbia stood Russia, and behind Russia stood Britain and France.

One week after the assassination of Franz Ferdinand, Germany’s Kaiser Wilhelm II pledged unconditional support to Austria-Hungary, however it chose to respond to the attack. With this so-called blank check assurance, Austria-Hungary declared war on Serbia on July 28, 1914. Within days, France, Germany, and Russia announced their own cascading declarations of war.

Thus, Europe marched toward war—or, rather, as one historian describes the consequences of careless decision making, the continent found itself “sleepwalking” its way to World War I.

How did World War I change the world?

World War I was incredibly destructive. But perhaps most tragic of all, the “war to end all wars'' ultimately did nothing of the sort. Historians assert that both the conflict and its aftermath sowed the seeds for a second—and even deadlier—world war just two decades later.

Although World War I did not curtail future conflict, it nevertheless transformed society across the United States, Europe, the Middle East, and sub-Saharan Africa. Let’s explore a few examples:

New Age of Warfare: World War I ushered in a new age of lethal military technology. These military innovations include landmines, flamethrowers, submarines, tanks, and fighter planes. Aerial photography allowed both sides to create sophisticated maps of their opponents’ positions. Long-range artillery gave soldiers the ability to shoot at enemies they could not see. And the introduction of weapons of mass destruction, including chemical gas, were used to break through the dug-in stalemates of trench warfare. The scale and severity of such combat led tens of thousands of veterans to experience debilitating psychological trauma. This condition, then known as shell shock, is now commonly referred to as post-traumatic stress disorder.

In addition, although previous wars were largely confined to the battlefield, World War I was a “total war.” The conflict saw the complete erosion of the distinction between civilian and military targets. Germany, for example, used submarines to attack civilian ships and used airships known as zeppelins to bomb cities in Britain. The war also featured mass killings and expulsions of particular ethnic groups. For example, Armenians were violently excluded from the Ottoman Empire, a practice that many scholars would later term genocide .

Innovations Beyond the Battlefield:  In addition to new forms of weaponry, many medical practices and common household items have their origins in war. During World War I, doctors began using sodium citrate to stop blood from clotting. Doctors also performed some of the first successful skin grafts, which paved the way for modern plastic surgery. Additionally, the invention of splints greatly reduced the lethality of certain injuries: before the war, four out of every five soldiers with a broken femur died; after the introduction of the splint, four out of every five survived.

The Great War also led to the development of Kotex, one of the first branded sanitary products (used as a cheaper and more absorbent wartime alternative to cotton bandages), the popularization of exercises like pilates (invented by a captured German bodybuilder to stay fit), and the rise in print cartoons (used both as military propaganda and to help civilians and veterans process the horrors of war).

Daylight Saving Time : Daylight saving time (DST) was developed during World War I to conserve energy and free up more daylight hours for battle. Although DST was meant to be a temporary fix, essays dating back decades argued for its implementation; in 1794, Benjamin Franklin made the case in financial (candle cost-savings), productivity (longer workdays), and moral (a remedy for laziness) terms. Although most of the world repealed DST when the first World War ended, World War II led to its quick re-adoption. DST was popularized as a long-term solution following the end of that conflict decades later. The year-round DST we observe in the United States was introduced in the winter of 1973 amidst a global energy crisis.

Vegetarian Sausage : : Before World War I, these modern grocery store staples didn’t exist. Vegetarian sausage was created in sausage-loving Germany during the war as a cheap way to add protein to meals amidst frequent food shortages. Cologne’s then-mayor Konrad Adenauer made his Kölner Wurst or “Cologne sausage” using soya, flour, corn, barley, and ground rice. Despite its use in wartime, the sausages were infamously bland. Meat substitutes available today have made big gains in texture and taste but rely on many of the same ingredients from Adenauer’s original recipe.

Plastic Surgery : Before World War I, people who experienced disfiguring wounds had limited options to choose from. However, as the number and magnitude of facial disfigurations skyrocketed among soldiers fighting in the First World War, the medical community worked quickly to invent reconstruction procedures. Dr. Harold Gillies is credited with the idea to use patients’ own facial tissue to decrease the chance of transplant rejection, leading to rapid innovation in the field of plastic surgery. Following this innovation, treatment capabilities ranged from successful skin grafts to the first sex reassignment surgeries.

Everyday Words and Phrases : Next time you “ace” a test, unexpected news leaves you “shell shocked,” or that highly anticipated movie turns out to be a “dud,” you’re using language directly handed down from wartime. From World War I, English gained words like “lousy,” which transformed from an adjective to describe lice infestations to mean weary. The British also refashioned the term“trench coat,” which transitioned from battlefield necessity to universal fashion statement. World War II added household brands Spam (a mashup of “spiced” and “ham”) and Jeep (from the initials GP, which described its wartime roots as a general purpose vehicle). The global entanglement also created a melting pot of cultural ideas and terms. For example, describing something comfortable or privileged as “cushy,” is a direct contribution to the English language from Indian troops who fought alongside the British in World War I.

Wristwatches : Before we could check the time with the phones in our pockets, most people had to dig out their pocket watch to accomplish this essential task. That proved to be quite inconvenient for soldiers in the trenches, who were also operating without church bells and factory whistles to orient themselves in time. Wristwatches, the obvious solution to this problem, were seen as feminine accessories before World War I, a perception that changed rapidly as they became a crucial part of soldiers’ gear. The phrase “synchronize your watches” came to symbolize their importance on the battlefield where fighting had to be precisely scheduled and timing was a vital tool for communication and survival.

Newsreels : The advent of the twenty-four-hour news cycle stems from one of the earliest forms of broadcast: newsreels. Without televisions, cell phones, or social media, people would line up at movie theaters to watch hour-long loops of news and entertainment features. Early video cameras were bulky, so newsreels rarely included war reporting at the start of World War I. Instead, early war news covered parades, sports events, and cultural moments like royal weddings. Yet as the war progressed and the public hungered for updates, newsreels began to include footage from the conflict. Video cameras produced unprecedented imagery for the time, including the launch of military ships, civilians fleeing their villages, prisoners of war , and cratered battlefields. Video documentation  led to a new awareness about wartime destruction.

Changing Roles for Women: As Europe’s militaries sent millions of men to the front lines, women played an increasingly important role in professional life back home.

Thousands of women gained a taste of personal and financial independence as they staffed factories, offices, and farms to support the war effort. Pointing to these valuable contributions, women’s rights groups successfully lobbied for suffrage (voting rights) in numerous countries between 1917 and 1920. (Workers’ rights groups also highlighted these efforts—from both men and women—to push for stronger unions and greater collective bargaining power).

Women’s fashion even changed during the war too. Metal shortages led governments to ask women to stop buying corsets, leading to the creation of brassieres. And as more women began to work outside the home, they increasingly adopted factory-safe attire such as pants.

Certainly not all women experienced economic advancement during this time. World War I widowed at least three million women. As a result, these women were left to face extreme financial hardship after the conflict.

Rise and Fall of Powers: The end of World War I marked a shift in global powers. The war culminated with the fall of major empires, such as the Ottoman Empire, and the rise of a new global power, the United States .

Source: National Geographic.

The End of World War I

World War I brought about the collapse of four empires: the Austro-Hungarian, German, Ottoman, and Russian.

In many cases, the victors of World War I absorbed territory from those former empires. Britain and France carved up land belonging to the Ottoman Empire. Meanwhile, Germany was forced to cede its colonies in Africa and the Pacific as part of the terms of the Treaty of Versailles. This peace treaty set the terms for the end of World War I in 1919. The breakup of these empires also resulted in the creation of new countries in Europe such as Czechoslovakia and Yugoslavia in addition to the reemergence of old ones like Poland.

With World War I leaving even Europe’s victors badly weakened, the global center of power began shifting across the Atlantic to the United States. Even before the war, the United States had surpassed Britain to become the world’s strongest economy. After the war, the United States emerged in an even more powerful position. In 1919, Washington was uniquely situated to shape the new international order. However, the nation balked at the opportunity, as the American public was largely uninterested in international leadership at the time. Instead,the country retreated into a period of isolationism.

It would take a second world war two decades later for the United States to fully become the global power it is today.

World War 1 started with a European conflict and gradually it developed into a World War. Militarism, nationalism, imperialism, and alliances increased the tensions among the European countries. The first reason, militarism, is known as the trend toward developing military resources, both for national defense and the protection of colonial interests.

Militarism indicated a rise in military disbursement and it extended to military and naval forces. It put more impact on the military men upon the policies of the civilian government. As a solution to problems militarism had a preference for force. This was one of the main reasons for the First World War. The second reason is there were too many alliances that frequently clashed with each other. Every country was pawning to safeguard others, creating intertwining mutual protection schemes.

They made alliances in secret, and they created a lot of mistrust and intuition among the European powers. Their general intuition stopped their diplomats to find a proper solution to many of the crises leading to war. Imperialism was the third reason for the First World War. As some areas of the world were left to colonize, nations were competing for subsisting colonies, and they were looking for enlarging their borders with adjacent countries. The fourth cause was nationalism. Nationalism is frequently insinuated to as identification with one’s own country and support for the country. Nationalism contains a strong recognition of a group of personnel with a political entity.

The support of individuals for their own country can become of one’s nation can become hatred of other nations. These were just some of the basic reasons for the war. Many people think that the instant reason for the war was because of the assassination of Archduke Francis Ferdinand, the successor to Austria-Hungary’s throne. Archduke Ferdinand was fired and murdered due to what was thought to be a political conspiracy. The Austro-Hungarian Empire suddenly doubted Serbian conspiracy in the assassination and looked to frame a response that would both punish Serbia, and make the world respect Austria-Hungary’s prestige and determination.

The Great War lasted four years. The war was finally over after four years and it took the lives of many people. On the eleventh hour of the eleventh day of the eleventh month of 1918, a cease-fire went into effect for all fighters. Though the war has been finished, the effects, are still seen perceptible in the world today.

In the aftermath of World War 1, the political, cultural, and social order of the world was drastically changed in many places, even outside the areas directly involved in the war. Old nations were removed, new nations were formed, international organizations set up, and many new and old ideas took a stronghold in people’s minds.

As Europe fell in debt from war investment, inflation beset the continent. In addition to this, the buoyancy of previous decades was relinquished and a discouraging, gloomy outlook on life was adopted after people had experienced the ferocity of warfare and the effects of the war were brutal.

The essay explores the causes of World War 1, which took place from 1914 to 1918. It begins with a brief overview of the war's timeline and the major countries involved, including the United Kingdom, France, Russia, Italy, Romania, Japan, the United States of America, Germany, Austria, Hungary, Bulgaria, and the Ottoman Empire. The essay then delves into the four main causes of the war: Militarism, Nationalism, Imperialism, and Alliances.

Militarism is discussed as the policy of maintaining a strong military force and a readiness to use it aggressively for defense. The significant arms buildup and military spending by various countries, including Germany, are highlighted as contributing factors to the outbreak of the war.

Nationalism is described as the strong attachment to one's own nation and culture. It is explained how nationalism led to conflicts, including the assassination of Archduke Franz Ferdinand, which triggered Austria's desire for revenge.

Imperialism, the expansion of a nation's power by dominating other countries, is presented as a factor due to the competition among European powers over control of African resources and territories.

Lastly, the essay discusses the role of Alliances, where countries formed partnerships to defend each other, often resulting in a domino effect of declarations of war.

Introduction

The effects of World War I can be seen around the world even now, more than one hundred years after its end; however, there is still no consensus as to its cause. In the words of Alfred Korzybski, “the destruction was brought about by nationalism, entangled alliances, narrow ethnic concerns, and desires for political gain – forces that are still with people today.” (cited in Levinson, 2014). Even though the majority of United States citizens did not have the direct experience of the terrific upset that the war caused in Europe, it can be argued that the country’s concern with championing democracy around the globe is one of its products (Levinson, 2014).

Many historians agree that an atmosphere of twentieth-century Europe was conducive to the creation of a complex mixture of economic, social, and political reasons that translated into powerful forces of imperialistic, nationalistic, and militaristic movements leading to the diplomatic crises of 1914 (Donaldson, 2014). Therefore, it can be said that the blame for the war could not be assigned to any individual country or a group of countries.

Nonetheless, the issue of responsibility was the main focus of the world in the years following the Armistice of 1918 (Donaldson, 2014). To this end, the Commission on the Responsibility of the Authors of the War and the Enforcement of Penalties met in Paris in 1919 (Donaldson, 2014). The investigation conducted by the commission showed that Germany and Austria, along with Turkey and Bulgaria as their allies, were responsible for the aggressive foreign policy tactics that led to the precipitation of the war (Donaldson, 2014).

The start of World War I was precipitated by the assassination of the heir to the Austro-Hungarian throne, Archduke Franz Ferdinand, on June 28, 1914 (Mulligan, 2010) The elimination of the high-standing official was carried out by the group of secret society members called Black Hand and directed by Bosnian Serb Danilo Ilić (Storey, 2009). The political objective of the murder was to separate Austria-Hungary’s South Slav provinces to combine them into Yugoslavia (Storey, 2009).

In response to the killing of their official, Austria-Hungary issued an ultimatum to Serbia that commanded its government to prosecute the assassins. The objective of the ultimatum was to make its terms so strict that Serbia would be forced to reject it, thereby giving an excuse for launching a small war against it (Storey, 2009). Taking into consideration that Serbia had diplomatic relationships with Russia strengthened by their shared Slavic ties, the Austro-Hungarian government decided to take precautions against the two countries declaring war on it and allied with Germany. It is agreed that Germany was not opposed to Austro-Hungarian bellicosity, but rather supported and encouraged it, thus providing one more reason for the precipitation of the Great War (Levinson, 2014).

Even though Serbia’s response to the ultimatum was placating, Austria-Hungary decided to take aggressive action and declare war. It is argued that the main reason for World War I was the web of entangling alliances among the countries having an interest in the conflict between Austro-Hungary and Serbia (Storey, 2009). Following the Austro-Hungarian declaration of war, the Russian monarch mobilized his army because of the binding commitment of the treaty signed by the two countries.

As a result, on August 3, 1914, Germany declared war on the Russian Empire (Levinson, 2014). France was bound by treaty to Russia, and, therefore, had to start a war on Austria-Hungary and Germany. Even though a treaty tying France and Britain was loosely worded, the latter country had “a moral obligation” to defend the former (Levinson, 2014). Therefore, Britain and its allies Australia, Canada, India, New Zealand, Japan, and the Union of South Africa also took a bellicose stance against Germany and offered their assistance in the military action against the country (Levinson, 2014). Thus, a gigantic web of entangling alliances pushed numerous countries to the precipice of war over what was intended to be a small-scale conflict between Austria-Hungary and Serbia.

Numerous other reasons led to World War I. The conflicting political interests of Russia and Japan over Manchuria and Korea resulted in a military defeat of Russia (Levinson, 2014). Therefore, the country wanted to restore its dignity by a victorious war. During the same period, a lot of small nations were seething with discontent over the Turkish and Austro-Hungarian rule, thereby providing an opportunity for the Russian Empire further to stir resentment by firing up nationalistic zeal under a pretense of pan-Slavic narrative (Levinson, 2014).

Austria-Hungary, on the other hand, sought an opportunity to establish its influence over a vast territory of mixed nations; the assassination of the heir to the Austro-Hungarian throne provided them with a perfect excuse for the initiation of the war. Political clashes in Germany were a reason for the country’s government to resort to the military conflict as a way of “averting civil unrest” (Levinson, 2014). Another factor that caused World War I was the desire of France to revenge a military defeat in the Franco-Prussian War of 1871 (Levinson, 2014).

It is impossible to name a single reason for the initiation of World War I. However, it is clear that the entangling web of alliances among numerous parties participating in the war, as well as complicated plots of governments and empires, led the small-scale dispute between Austria-Hungary and Serbia escalating into a military conflict that swept the entire world.

The Impact and Origins of World War i

This essay about World War I, also known as the Great War, discusses its origins and impacts. It highlights the rapid industrialization and imperial ambitions of major European powers, the rise of nationalism, and the complex alliance systems that set the stage for conflict. The assassination of Archduke Franz Ferdinand triggered a chain reaction, leading to a devastating global war. The war’s profound social, economic, and geopolitical consequences reshaped the world, ultimately setting the stage for future conflicts.

How it works

This intensive fight for global influence worsened competitions and suspicions existing, creates fat land for a conflict.

• Ray Kurzweil on how AI will transform the physical world

The changes will be particularly profound in energy, manufacturing and medicine, says the futurist

B Y THE TIME children born today are in kindergarten, artificial intelligence ( AI ) will probably have surpassed humans at all cognitive tasks, from science to creativity. When I first predicted in 1999 that we would have such artificial general intelligence ( AGI ) by 2029, most experts thought I’d switched to writing fiction. But since the spectacular breakthroughs of the past few years, many experts think we will have AGI even sooner—so I’ve technically gone from being an optimist to a pessimist, without changing my prediction at all.

After working in the field for 61 years—longer than anyone else alive—I am gratified to see AI at the heart of global conversation. Yet most commentary misses how large language models like Chat GPT and Gemini fit into an even larger story. AI is about to make the leap from revolutionising just the digital world to transforming the physical world as well. This will bring countless benefits, but three areas have especially profound implications: energy, manufacturing and medicine.

Sources of energy are among civilisation’s most fundamental resources. For two centuries the world has needed dirty, non-renewable fossil fuels. Yet harvesting just 0.01% of the sunlight the Earth receives would cover all human energy consumption. Since 1975, solar cells have become 99.7% cheaper per watt of capacity, allowing worldwide capacity to increase by around 2m times. So why doesn’t solar energy dominate yet?

The problem is two-fold. First, photovoltaic materials remain too expensive and inefficient to replace coal and gas completely. Second, because solar generation varies on both diurnal (day/night) and annual (summer/winter) scales, huge amounts of energy need to be stored until needed—and today’s battery technology isn’t quite cost-effective enough. The laws of physics suggest that massive improvements are possible, but the range of chemical possibilities to explore is so enormous that scientists have made achingly slow progress.

By contrast, AI can rapidly sift through billions of chemistries in simulation, and is already driving innovations in both photovoltaics and batteries. This is poised to accelerate dramatically. In all of history until November 2023, humans had discovered about 20,000 stable inorganic compounds for use across all technologies. Then, Google’s GN o ME AI discovered far more, increasing that figure overnight to 421,000. Yet this barely scratches the surface of materials-science applications. Once vastly smarter AGI finds fully optimal materials, photovoltaic megaprojects will become viable and solar energy can be so abundant as to be almost free.

Energy abundance enables another revolution: in manufacturing. The costs of almost all goods—from food and clothing to electronics and cars—come largely from a few common factors such as energy, labour (including cognitive labour like R & D and design) and raw materials. AI is on course to vastly lower all these costs.

After cheap, abundant solar energy, the next component is human labour, which is often backbreaking and dangerous. AI is making big strides in robotics that can greatly reduce labour costs. Robotics will also reduce raw-material extraction costs, and AI is finding ways to replace expensive rare-earth elements with common ones like zirconium, silicon and carbon-based graphene. Together, this means that most kinds of goods will become amazingly cheap and abundant.

These advanced manufacturing capabilities will allow the price-performance of computing to maintain the exponential trajectory of the past century—a 75-quadrillion-fold improvement since 1939. This is due to a feedback loop: today’s cutting-edge AI chips are used to optimise designs for next-generation chips. In terms of calculations per second per constant dollar, the best hardware available last November could do 48bn. Nvidia’s new B 200 GPU s exceed 500bn.

As we build the titanic computing power needed to simulate biology, we’ll unlock the third physical revolution from AI : medicine. Despite 200 years of dramatic progress, our understanding of the human body is still built on messy approximations that are usually mostly right for most patients, but probably aren’t totally right for you . Tens of thousands of Americans a year die from reactions to drugs that studies said should help them.

Yet AI is starting to turn medicine into an exact science. Instead of painstaking trial-and-error in an experimental lab, molecular biosimulation—precise computer modelling that aids the study of the human body and how drugs work—can quickly assess billions of options to find the most promising medicines. Last summer the first drug designed end-to-end by AI entered phase-2 trials for treating idiopathic pulmonary fibrosis, a lung disease. Dozens of other AI -designed drugs are now entering trials.

Both the drug-discovery and trial pipelines will be supercharged as simulations incorporate the immensely richer data that AI makes possible. In all of history until 2022, science had determined the shapes of around 190,000 proteins. That year DeepMind’s AlphaFold 2 discovered over 200m, which have been released free of charge to researchers to help develop new treatments.

Much more laboratory research is needed to populate larger simulations accurately, but the roadmap is clear. Next, AI will simulate protein complexes, then organelles, cells, tissues, organs and—eventually—the whole body.

This will ultimately replace today’s clinical trials, which are expensive, risky, slow and statistically underpowered. Even in a phase-3 trial, there’s probably not one single subject who matches you on every relevant factor of genetics, lifestyle, comorbidities, drug interactions and disease variation.

Digital trials will let us tailor medicines to each individual patient. The potential is breathtaking: to cure not just diseases like cancer and Alzheimer’s, but the harmful effects of ageing itself.

Today, scientific progress gives the average American or Briton an extra six to seven weeks of life expectancy each year. When AGI gives us full mastery over cellular biology, these gains will sharply accelerate. Once annual increases in life expectancy reach 12 months, we’ll achieve “longevity escape velocity”. For people diligent about healthy habits and using new therapies, I believe this will happen between 2029 and 2035—at which point ageing will not increase their annual chance of dying. And thanks to exponential price-performance improvement in computing, AI -driven therapies that are expensive at first will quickly become widely available.

This is AI ’s most transformative promise: longer, healthier lives unbounded by the scarcity and frailty that have limited humanity since its beginnings. ■

Ray Kurzweil is a computer scientist, inventor and the author of books including “The Age of Intelligent Machines” (1990), “The Age of Spiritual Machines” (1999) and “The Singularity is Near” (2005). His new book, “The Singularity is Nearer: When We Merge with AI”, will be published on June 25th.

Fact-checking Biden and Trump's claims at the first debate

Forget alternative facts and political spin: Thursday's presidential debate was more like a tsunami of falsity.

Former President Donald Trump unleashed a torrent of misinformation on topics from terrorism to taxes during the first debate of the 2024 general election, while President Joe Biden flubbed figures and facts about military deaths and insulin prices.

More than a dozen NBC News reporters, editors and correspondents fact-checked the key claims the presidential candidates made Thursday night. Here they are by topic:

Economy, trade and health care

Fact check: did biden inherit 9% inflation.

“He also said he inherited 9% inflation. Now, he inherited almost no inflation, and it stayed that way for 14 months, and then it blew up under his leadership,” Trump said about Biden.

This is false.

The inflation rate when Biden took office in January 2021 wasn’t 9%. It was 1.4%. It has risen on his watch, peaking at about 9.1% in June 2022, but by last month it had come down to 3.3%. Pandemic-related stimulus policies put in place by both Trump and Biden were blamed, in part, for the rise in the inflation rate.

Fact check: Did Biden lower the cost of insulin to $15 a shot?

“We brought down the price of prescription drugs, which is a major issue for many people, to $15 for an insulin shot — as opposed to $400,” Biden said.

Biden capped the cost of insulin at $35 a month under Medicare, not $15 a shot, and some drug companies have matched that cap. The price cap doesn’t apply to everyone , however. 

What’s more, Biden’s also significantly overstating how much insulin cost before the change. A 2022 report by the Department of Health and Human Services found that patients using insulin spent an average of $434 annually on insulin in 2019 — not $400 a shot.

Fact check: Did Trump lower the cost of insulin?

Trump claimed credit for lowering the cost of insulin for seniors, saying, “I am the one who got the insulin down for the seniors.”

That is mostly false.

In 2020, Trump created a voluntary program under Medicare Part D. The program allowed Medicare Part D plans to offer some insulin products for no more than $35 per month. It was active from 2021 to 2023, with fewer than half of the plans participating each year. 

In 2022, Biden signed the Inflation Reduction Act, which included a provision that lowered the out-of-pocket cost for people on Medicare to $35 a month and covered all insulin products. The cap didn’t apply to those with private insurance. However, after the law was implemented, insulin manufacturers voluntarily lowered the out-of-pocket cost to $35 a month for people with private insurance.

Fact check: Does Biden want to raise ‘everybody’s taxes’ by four times?

“Nobody ever cut taxes like us. He wants to raise your taxes by four times. He wants to raise everybody’s taxes by four times,” Trump claimed. “He wants the Trump tax cuts to expire.”

Biden’s tax plan “holds harmless for 98% of households,” said Kyle Pomerleau, senior fellow at the conservative American Enterprise Institute. And Biden wants to extend the majority of the Trump tax cuts, too, though he has advocated for hiking taxes on very high earners.

Fact check: Biden said the U.S. trade deficit with China is at its lowest since 2010

“We are at the lowest trade deficit with China since 2010,” Biden said.

This is true.

The U.S. had $279 billion more in imports than exports to China last year, the lowest trade deficit with the world’s second-largest economy since 2010. The highest deficit in recent years was $418 billion, in 2018, when Trump began a trade war with China. 

The decline has been driven largely by tariffs that Trump imposed in office and that Biden has maintained and in some cases expanded.

Fact check: Are immigrants taking ‘Black jobs’?

Asked about Black voters who are disappointed with their economic progress, Trump claimed Black Americans are losing their jobs because of illegal border crossings under Biden’s administration.

“The fact is that his big kill on the Black people is the millions of people that he’s allowed to come through the border. They’re taking Black jobs now,” Trump said.

There’s no evidence that undocumented immigrants are taking jobs away from Black Americans. In fact, according  to the Bureau of Labor Statistics , the Black unemployment rate fell to 4.8% in April 2023 — an all-time low. Before that, the Black unemployment rate was as high as 10.2% in April 2021.

Immigration

Fact check: did trump end catch and release.

“We ended ‘catch and release,’” Trump said.

Trump did not end “catch and release,” a term used to describe the practice of releasing migrants into the country with court dates while they await court hearings. The U.S. doesn’t have enough facilities to detain every migrant who crosses the border until they can see judges, no matter who is president, so Trump — like Barack Obama before him and Biden after him — released many migrants back into the U.S.

Fact check: Did the Border Patrol union endorse Biden?

“By the way, the Border Patrol endorsed me, endorsed my position,” Biden said.

The National Border Patrol Council, the labor union for U.S. Border Patrol agents and staff members, has endorsed Trump. 

“The National Border Patrol Council has proudly endorsed Donald J. Trump for President of the United States,” the group’s vice president, Hector Garza, said in a statement shared exclusively with NBC News. 

The union posted on X , “to be clear, we never have and never will endorse Biden.”

Biden may have been referring to a Senate immigration bill that he backed, which earned the union’s endorsement .

Fact check: Did Trump have ‘the safest border in the history of our country’?

“We had the safest border in the history of our country,” Trump said.

It’s a clear exaggeration. In 2019, the last year before the Covid-19 pandemic brought down border crossings, there were roughly 860,000 illegal border crossings, far more than in any year during the Obama administration.

Fact check: Trump says Biden is allowing ‘millions’ of criminals to enter U.S.

“I’d love to ask him … why he’s allowed millions of people to come in from prisons, jails and mental institutions to come into our country and destroy our country,” Trump said.

There is no evidence of this.

Venezuela doesn’t share law enforcement information with U.S. authorities, making it very hard to verify criminal histories of immigrants coming to the U.S. But there’s no evidence that Venezuela is purposefully sending “millions” of people from mental institutions and prisons to the U.S.

Fact check: Did Virginia’s former governor support infanticide?

“They will take the life of a child in the eighth month, the ninth month and even after birth. After birth. If you look at the former governor of Virginia, he was willing to do so, and we’ll determine what we do with the baby. Meaning we’ll kill the baby. ... So that means he can take the life of the baby in the ninth month and even after birth. Because some states, Democrat-run, take it after birth. Again, the governor, the former Virginia governor, put the baby down so that we decide what to do with it. He’s willing to, as we say, rip the baby out of the womb in the ninth month and kill the baby. Nobody wants that to happen, Democrat or Republican; nobody wants it to happen,” Trump said.

While some Democrats support broad access to abortion regardless of gestation age, infanticide is illegal, and no Democrats advocate for it. Just 1% of abortions are performed after 21 weeks’ gestation, according to the Centers for Disease Control and Prevention .

Trump first made the claim in 2019, after Virginia’s governor at the time, Ralph Northam, made controversial remarks in discussing an abortion bill. NBC News debunked the claim then, reporting that Northam’s remarks were about resuscitating infants with severe deformities or nonviable pregnancies. 

Asked on a radio program what happens when a woman who is going into labor desires a third-trimester abortion, Northam noted that such procedures occur only in cases of severe deformities or nonviable pregnancies. He said that in those scenarios, “the infant would be resuscitated if that’s what the mother and the family desired, and then a discussion would ensue between the physicians and the mother.”

Terrorism, foreign policy and the military

Fact check: trump said there was ‘no terror’ during his tenure.

“That’s why you had no terror, at all, during my administration. This place, the whole world, is blowing up under him,” Trump said.

There were two ISIS-inspired terrorist attacks while Trump was president. The first occurred in October 2017, when Sayfullo Saipov killed eight people and injured a dozen more in a vehicle ramming attack on the West Side Highway bike path in New York City. The second occurred in December 2017, when Akayed Ullah injured four people when he set off a bomb strapped to himself.

Fact check: Biden suggests no troops died under his watch

“The truth is I’m the only president this century that doesn’t have any this decade and any troops dying anywhere in the world like he did,” Biden said.

The Defense Department confirmed that 13 U.S. service members were killed in a suicide bombing attack at Abbey Gate at the Kabul airport by a member of ISIS-K as the U.S. was leaving Afghanistan. 

Environment

Fact check: did trump have the ‘best environmental numbers ever’.

“During my four years, I had the best environmental numbers ever, and my top environmental people gave me that statistic just before I walked on the stage, actually,” Trump said.

The figure Trump is referring to is the fact that carbon emissions fell during his administration. He posted the talking points his former Environmental Protection Agency chief emailed him on social media before the debate.

And it’s true that carbon emissions are falling — they have been dropping for years. Emissions particularly plunged in 2020, dropping to levels around those in 1983 and 1984. That drop was in large part thanks to Covid lockdowns, and emissions rose again when air travel and in-person working resumed. 

Still, climate activists and experts are quick to note that those drops are nowhere near enough to head off predicted catastrophic effects of global warming. Other major countries cut their emissions at a much faster rate during the Trump administration.

Fact check: The Jan. 6 crowd was not ‘ushered in’ by the police

“If you would see my statements that I made on Twitter at the time and also my statement that I made in the Rose Garden, you would say it’s one of the strongest statements you’ve ever seen. In addition to the speech I made in front of, I believe, the largest crowd I’ve ever spoken to, and I will tell you, nobody ever talks about that. They talk about a relatively small number of people that went to the Capitol and, in many cases, were ushered in by the police. And as Nancy Pelosi said, it was her responsibility, not mine. She said that loud and clear,” Trump said.

During a lengthy answer to a question about whether he would accept the result of the 2024 election and say all political violence is unacceptable, Trump made several false statements, including the claim that police “ushered” rioters into the U.S. Capitol and that then-House Speaker Nancy Pelosi, D-Calif., said it was her responsibility to keep the chamber safe. 

Video and news reports of the Jan. 6 riots clearly captured the U.S. Capitol under attack by pro-Trump crowds who overran the law enforcement presence around and inside the complex. 

On Pelosi, Trump was most likely referring to video shot by Pelosi’s daughter Alexandra for an HBO documentary that showed her during the events of Jan. 6, 2021, tensely wondering how the Capitol was allowed to be stormed.

“We have responsibility, Terri,” Pelosi tells her chief of staff, Terri McCullough, as they leave the Capitol in a vehicle. “We did not have any accountability for what was going on there, and we should have. This is ridiculous.”

“You’re going to ask me in the middle of the thing, when they’ve already breached the inaugural stuff, ‘Should we call the Capitol Police?’ I mean the National Guard. Why weren’t the National Guard there to begin with?” Pelosi says in the video. 

“They clearly didn’t know, and I take responsibility for not having them just prepare for more,” she says. 

Many allies of Trump have tried for the more than three years since the riots to paint Pelosi as somehow being responsible for the violence. Some Trump-backing Republicans have, for example, falsely claimed that she blocked the National Guard from going to the Capitol during the riots.

And everything else ...

Fact check: trump skipped world war i cemetery visit because the soldiers who died were ‘losers’.

Biden said that Trump “refused to go to” a World War I cemetery and that “he was standing with his four-star general” who said Trump said, “I don’t want to go in there, because they’re a bunch of losers and suckers.”

In 2018, during a trip to France, Trump canceled a visit to an American cemetery near Paris, blaming weather for the decision. 

But in September 2020, The Atlantic reported that Trump had axed the visit because he felt that those who’d lost their lives and been buried there were “losers.” The magazine cited “four people with firsthand knowledge of those discussions.”

According to The Atlantic, Trump said: “Why should I go to that cemetery? It’s filled with losers.” In another conversation, The Atlantic reported, Trump said the 1,800 American Marines who died were “suckers.” 

Several media outlets confirmed the remarks, and Trump’s former White House chief of staff John Kelly also said those specific comments were true.

Fact check: Trump says Biden didn’t run for president due to 2017 Charlottesville rally

“He made up the Charlottesville story, and you’ll see it’s debunked all over the place. Every anchor has — every reasonable anchor has debunked it, and just the other day it came out where it was fully debunked. It’s a nonsense story. He knows that, and he didn’t run because of Charlottesville. He used that as an excuse to run,” Trump said about Biden.

The “Unite the Right” rally in Charlottesville, Virginia, in 2017 featured torch-bearing white supremacists marching to protest the removal of a Robert E. Lee statue and chanting racist slogans like “You will not replace us.” It turned deadly when a car plowed into a crowd .

In recent months, Trump has downplayed the violence, saying it was “nothing” compared to recent pro-Palestinian protests on university campuses.

Meanwhile, Biden has always pointed to Trump’s 2017 comments as the primary reason he decided to seek the presidency in 2020, including in his campaign announcement video back in April 2019 .
