"World War I (1914-1918) was a conflict that involved more countries and caused greater destruction than any other war up to its time. Following an assassination in Bosnia-Herzegovina, a system of military  alliances (agreements) plunged the main European powers into a war that lasted four years. The war took the lives of about 9 million troops and more than 6 million civilians. World War I is sometimes called the Great War."
