World War I
World War I started with the shot heard around the world: the assassination of Archduke Franz Ferdinand of Austria on July 28, 1914, in Sarajevo. The diplomatic crisis soon evolved into a conflict among international military alliances as Austria-Hungary and Germany joined up against the Triple Entente of the United Kingdom, France and the Russian Empire. As the conflict expanded around the world, more nations entered the battle: the United States and Japan joined the Allies and the Ottoman Empire aligned itself with the Central Powers. By the end of the war on November 11, 1918, more than 70 million troops had been mobilized into one the largest conflicts in history. In the war's aftermath, the map of Europe was redrawn. Several of the great powers ceased to exist and smaller independent nations were created. The League of Nations was formed with the aim of preventing another war. However, in the decades following the defeat of Germany, fascism and the conditions for the start of World War II soon took root. This is a collection of DW's content on World War I.
