This multi-ethnic imperium wasn't well suited to the nationalistic spirit of the times. Serbia wanted to incorporate the empire's Serbian- and Croatian-speaking territories into its own kingdom, a move that Austria-Hungary saw as a fundamental challenge to their core governing ideology: Habsburg dynastic legitimacy trumps ethnic nationalism.
He was joined in the city by seven Serbian terrorists there to kill him, in hopes of removing a prominent moderate from the line of succession and heightening the tensions between Vienna and its South Slavic subjects.
The first assassin was standing near a policeman and didn't use his weapon. The second assassin tossed a grenade that injured several people. The motorcade then continued past the other assassins, none of whom acted as they lacked clear shots in the commotion. The assassins believed their plot had failed. Franz Ferdinand ordered his car to turn around so he could visit people injured by the grenade but his driver misunderstood, and continued on the original route where, while attempting to turn around, his car stalled.
By chance, Gavrilo Princip had by this time moved over to Franz Joseph Street and he was able to take the fatal shot.
The main participants in the war mobilized over the course of about a week. First Austria-Hungary declared war on Serbia after Serbia refused to acceed to Vienna's extensive demands regarding Serbian support for anti-Austrian groups. Then Russia declared war on Austria-Hungary. This required Germany to go to war in defense of its ally. German war planning assumed that any war with Russia would expand to include war with France, and the operational plan called for attacking France first.
Thus the main practical step Germany took to defend Austria was to launch a preemptive attack on France and Belgium, neither of whom had officially entered the war yet. The violation of Belgian neutrality brought Britain into the war and it was off to the races.
But the literal timing shouldn't confuse you — it had long been French policy to support Serbia against Austria in hopes of initiating a war in which Russia would help France fight Germany, which was far too powerful for France to fight alone. The German war plan called for the swiftest possible capture of Paris, hoping to knock France out of the war before Russia could fully mobilize its large but low-tech military.
Belgium was not part of any pre-war alliances and attempted to stay neutral in the war. The attack on Belgium brought the British Empire into the war, with British politicians citing their country's obligation to uphold Belgian neutrality. This was a risky move on Germany's part, but German war-planning long regarded a quick, decisive blow against France as the best possible hope of winning a two-front war. Right from the outset things did not go Germany's way.
West Point. In a sense, this September conflict was the decisive battle of the war. Germany's advance into France was halted by a combined Franco-British army on the outskirts of Paris near the Marne River and the German army was forced to fall back.
In these early phases, the war was moving too quickly for the opposing armies to have much in the way of fixed positions, and the hasty defense of the Paris suburbs included reinforcements being sent to the front from the city via a rapidly assembled fleet of urban taxis. The battle was followed by the so-called "race to the sea" in which German and Allied forces tried and failed to outflank each other until the lines reached all the way to the North Sea and no more battles of manouever were possible.
The stalemated Western Front with its trench warfare came next. Germany's strategic war plan — knock France out quickly so troops could be sent back east to fight Russia — had essentially failed. Combined with the defeat at the battle of the Marne, a victory by the numerically superior Russian forces could have crushed the German war effort in its crib.
Instead, the Germans were victorious. The Russians scored a tactical victory at Gumbinnen, but instead of pressing the advantage, they waited for the Second Army to arrive. The Germans audaciously moved south to face the Second Army before it could combine its strength with the First. German forces were aided by exceedingly poor Russian communication security — Russian troops hadn't mastered even basic cryptography, so German intelligence was aware of how poorly coordinated the two Russian armies were.
Those two wins prevented the Russians from taking strategic initiative against Germany in the East. This map illustrates the meanderings of the HMS Orvieto, one of the British ships assigned to Northern Patrol — the main naval operation dedicated to enforcing a British blockade of Germany and her allies. The blockade was meant to halt Germany's trade with the Western Hemisphere and it was so successful that it led to very little drama. Exporters in the Americas didn't like the blockage, but they didn't seriously try to challenge it either.
And with Britain and France diverting manpower to the war, both major Allied powers started demanding more imports, which created new markets for commodity producers. Unlike 19th-century blockades that were limited to war materiel or cash crops, the British considered everything — including food — to be contraband of war.
The blockade severely stressed the Central Powers' economies. Most important, however, was the blockade's interaction with global diplomacy. When the British attempted a similar blockage against Napoleonic France, the United States became embroiled in conflict with Britain leading to the War of The World War I blockade, by contrast, merely tightened the US-UK commercial relationship: the Wilson administration essentially respected the blockade of Europe while protesting Germany's efforts to use submarines to stymie American trade with Britain.
Germany's surface fleet was largely unable to to stand in battle against the vastly superior British Royal Navy. But the new technology of the submarine gave Germany the means to harass Allied shipping despite its weakness on the surface. In , they initiated a kind of underwater blockade — attacking ships bound for Britain as a countermeasure to the near-total Allied knockout of Germany's transatlantic trade.
But Germany didn't have nearly sufficient submarine strength to cut off all Allied shipping. What's more, unlike surface ships, submarines couldn't really threaten ships and board them. They could only attack with stealth. That led to the sinking of several ships with Americans aboard, which badly damaged US-German relations. Seeking to appease President Wilson, Germany halted unrestricted submarine warfare.
But in February , the Germans changed their minds again — setting themselves on a course that would drag the United States into the war. Avidius via Wikimedia.
The nominal cause of the war was Austria-Hungary's effort to punish Serbia for its sponsorship of anti-Austrian terrorism, and in the Habsburgs succeeded. The entire grand web of alliances neither deterred an Austrian attack on Serbia nor prevented the Austrians from winning. By the end of the year, the remnants of the Serbian army had retreated into Albania and been evacuated by sea. Allied forces would eventually liberate Serbia in , moving through Greece and Bulgaria.
The Serbian state enlarged to incorporate Bosnia-Herzegovenia, Croatia, Slovenia, and Macedonia after the war and became known as Yugoslovia until Public domain map via wikimedia. Italy did not join the war in its first year, and had been allied with Germany and Austria-Hungary during the pre-war years. But Italian nationalists had designs on some Italian-speaking lands still ruled by the Habsburgs as well as elements of the Adriatic coast that had historically been ruled by the Republic of Venice.
In the Treaty of London, the Allies succeeded in tempting Italy to enter the war on their side, promising them healthy slices of Austro-Hungarian territory. The actual fighting on the Italian Front was even more static and futile than the Western Front. So much so that there were 12 different Battles of the Isonzo, fought near a river in contemporary Slovenia.
These 12 battles together accounted for half of Italy's total casualties during the war and as illustrated on the map scarcely moved the frontier at all. In essence, Italy's war dead served as a massive diversionary tactic, occupying Austro-Hungarian and German troops who otherwise could have been fighting in Russia or France. Damien Felton. British forces, with assistance from the French navy, hatched a daring plan for an amphibious assault on the Gallipoli Peninsula in Turkey.
Had they succeeded in capturing the peninsula, Allied naval forces could have sailed through the Dardanelles Strait up into the Sea of Marmara and supported an attack on the Ottoman Empire's capital of Istanbul. That would have opened the door to direct Allied communication between the Western and Eastern Fronts.
Instead, Turkey kept the Allied troops bottled up and after months of fighting, they retreated. Heavy participation of volunteers from Australia and New Zealand in the campaign makes it an iconic moment in those nations' military histories even as the Turkish victory is celebrated in that country.
Verdun was one of the longest and costliest battles of the Western Front, raging from February to December of About , people were killed for the sake of moving the front line about 5 miles.
At the outset of the battle, German military officials had concluded that they had no way of puncturing Franco-British defenses and winning the war.
Their plan, instead, was to take advantage of the fact that the battle lines were on French soil to trick the Allies into defeating themselves. 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.
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 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 , restricted the use of chemical and biological agents in warfare and remains in effect today.

When World War I broke out across Europe in , President Woodrow Wilson proclaimed the United States would remain neutral, and many Americans supported this policy of nonintervention.
However, public opinion about neutrality started to change after the sinking of the British For four years, from to , World War I raged across Europe's western and eastern fronts, after growing tensions and then the assassination of Archduke Franz Ferdinand of Austria ignited the war.
Trench warfare and the early use of tanks, submarines and airplanes meant the The instability created in Europe by the First World War set the stage for another international conflict—World War II—which broke out two decades later and would prove even more devastating.
Rising to power in an economically and politically unstable Germany, Adolf World War I was unlike any conflict the world had ever seen. Europe by Almost exactly a century before, a meeting of the European states at the Congress of Vienna had established an international order and balance of power that lasted for almost a century. By , however, a multitude of forces were threatening to tear it apart.
World War I, which lasted from until , introduced the world to the horrors of trench warfare and lethal new technologies such as poison gas and tanks. The result was some of the most horrific carnage the world had ever seen, with more than 16 million military personnel Trenches—long, deep ditches dug as protective defenses—are When Nicholas declared war against Germany and Austria-Hungary in July , he was absolute ruler of a realm of nearly million people that stretched from Central On the night of April 3, , President Woodrow Wilson began to suffer from a violent cough.
His condition quickly worsened to the point that his personal doctor, Cary Grayson, thought the president might have been poisoned. Grayson later described the long night spent at Live TV. This Day In History. Following the assassination, Serbia and Austria - Hungary went to war.
The war grew as a result of interlocking alliances. Europe was divided into two coalitions: the Triple Alliance and the Triple Entente. Then, a domino effect began. Most of the battles of World War I took place in Europe, and willingly or not, the people of most of the countries were somehow active in the conflict. A total of 13 million German citizens fought in the war between and Nayar, Baldev Raj and Paul, T. Cambridge University Press, Boissoneault, Lorraine.
