Assassination in Sarajevo

The direct cause of the First World War was a successful attempt to murder the successor to the Austro-Hungary throne in Sarajevo in June 1914. Soon, two blocs stood against each other: the Triple Entente (France, the UK and Russia, supported by the US in 1917) and the Central Powers (Germany and Austro-Hungary). Although a quick ending of the fights was hoped for, the war continued until 1918 and even longer in some regions, bringing much damage and fundamental changes on international arena.
