On 28 June 1914, Archduke Franz Ferdinand, heir to the throne of Austria-Hungary was assassinated along with his wife by a Serbian nationalist in Sarajevo, Bosnia. This event led to the outbreak of World War I one month later. On the same day in 1919, representatives of the defeated Germany were forced to sign the punitive Treaty of Versailles, ending the war but not solving the problems that later led to World War II.
