World War One was the war to end all wars.
It was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918.
More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history.
Over nine million combatants and seven million civilians died as a result of the war.
The trigger for the war was the assassination of Archduke Franz Ferdinand of Austria.
This set off a diplomatic crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia.
On 28 July, the Austro-Hungarians declared war on Serbia. As Russia mobilised in support of Serbia, Germany invaded neutral Belgium and Luxembourg before moving towards France, leading the United Kingdom to declare war on Germany.
After the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, but the Germans stopped its invasion of East Prussia. In November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers; Romania joined the Allies in 1916, as did the United States in 1917.
The war lasted 4 years, 3 months and 2 weeks.
The main results were the end of the German, Russian, Ottoman, and Austro-Hungarian empires. Formation of new countries in Europe and the Middle East. Transfer of German colonies and regions of the former Ottoman Empire to other powers and establishment of the League of Nations.
