when and where did the first world war start
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, as a result, 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.
World War I World War I (often abbreviated as WWI or WW1), also known as the First World War or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as the "war to end all wars",[7] it led to the mobilization of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history.[8][9] An estimated nine million combatants and seven million civilians died as a direct result of the war, while it is also considered a contributory factor in a number of genocides and the 1918 influenza epidemic, which caused between 50 and 100 million deaths worldwide.[10] Military losses were exacerbated by new technological and industrial developments and the tactical stalemate caused by grueling trench warfare. It was one of the deadliest conflicts in history and precipitated major political changes, 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 about twenty years later.[11]
World War I World War I (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 70Â 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 paved the way for major political changes, including revolutions in many of the nations involved. Unresolved rivalries still extant at the end of the conflict contributed to the start of the Second World War only twenty-one years later.[8]
