when did the first world war 1 start and end
World War I World War I (often abbreviated as WWI or WW1), also known as the First World War, the Great War, or the War to End All Wars,[5] 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.[6][7] Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history and precipitated major political change, including the Revolutions of 1917–1923 in many of the nations involved. Unresolved rivalries at the end of the conflict contributed to the start of the Second World War twenty-one years later.[8]

World War I Between 1908 and 1914, the Balkans had been destabilised by the combination of a weakened Ottoman Empire, the 1912–1913 Balkan Wars and competing Russian and Austro-Hungarian objectives.[13] On 28 June 1914, Gavrilo Princip, a Bosnian Serb Yugoslav nationalist, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand in Sarajevo, leading to the July Crisis.[14][15] On 23 July, Austria-Hungary issued an ultimatum to Serbia; interlocking alliances quickly drew in all the major European powers with their respective colonial empires and the conflict rapidly spread across the globe.
World War I The trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a diplomatic crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia,[11][12] and entangled international alliances formed over the previous decades were invoked. Within weeks, the major powers were at war and the conflict soon spread around the world.
