The assassination on 28 June 1914 of Archduke Franz Ferdinand of Austria, the heir to the throne of Austria-Hungary, was the proximate trigger of the war. Long-term causes, such as imperialistic foreign policies of the great powers of Europe, including the German Empire, the Austro-Hungarian Empire, the Ottoman Empire, the Russian Empire, the British Empire, France, and Italy, played a major role. Ferdinand's assassination by a Yugoslav nationalist resulted in a Habsburg ultimatum against the Kingdom of Serbia. Several alliances formed over the past decades were invoked, so within weeks the major powers were at war; via their colonies, the conflict soon spread around the world.
