During 1910-1945, the Japanese occupied the Korean peninsula. In 1945, the U.S. and Soviet forces drove out the Japanese from Korea. The Soviets occupied the North and the U.S. occupied the South. A line that divided the peninsula was made at the 38th parallel. Japan unconditionally surrendered in September 2nd, 1945 after atomic bombs were dropped on Hiroshima on the 6th and Nagasaki on the 9th of August. North Korea was founded and led by Kim Il Sung and the South was led by another government and leader. Both sides claimed sovereignty over all of Korea. The North then invaded the South and shattered the South's forces. The South asked the UN for help and the UN intervened. UN forces drove the North to the Yalu river(the border between China and Korea) The Chinese warned the UN not to approach the river but the UN crossed the river which led to the Chinese becoming involved. The Chinese then forced the UN back to the 38th parallel. A stalemate resulted between both sides. The Chinese and UN signed an armistice but not a treaty. Korea is still technically at war and a DMZ was created at the border of North and South Korea.
