World War 1 was one of the deadliest conflicts in history sparked by militarism, alliances and imperialism in Europe. The assassination of Archduke Franz Ferdinand led Austria-Hungary to issue an ultimatum to Serbia, pulling the allied countries into war. Trench warfare led to millions of casualties until the United States entry into the war in 1917 helped tip the tide in favor of the allied powers. Germany surrendered in 1918, and the punitive Versailles Treaty forced it to accept full blame and pay massive reparations, sowing resentment and setting the stage for WWII.
