Two world wars and an economic depression dominated the first half of the 20th century. The First World War was fought between 1914 and 1918. It started when Archduke Franz Ferdinand of Austria was assassinated by the Yugoslav nationalist Gavrilo Princip. Most European nations were drawn into the war, which was fought between the Entente Powers (France, Belgium, Serbia, Portugal, Russia, the United Kingdom, and later Italy, Greece, Romania, and the United States) and the Central Powers (Austria-Hungary, Germany, Bulgaria, and the Ottoman Empire). The war left more than 16 million civilians and military dead. Over 60 million European soldiers were mobilised from 1914 to 1918.
