The Korean War broke out on June 25, 1950, when North Korean troops crossed the 38th parallel, the dividing line between the two Koreas, invading the South. The United Nations forces from 16 countries, including the United States, Britain, Turkey, and Australia, supported the South against the communist North backed by China.
