On 9 August 1945, as agreed by the Allies at the Yalta Conference, the Soviet Union declared war on Japan and advanced into Korea. The US government requested that the Soviet advance stop at the 38th parallel. The US forces were to occupy the area south of the 38th parallel, including the capital, Seoul. This division of Korea into two zones of occupation was incorporated into General Order No. 1 which was given to Japanese forces after the surrender of Japan on 15 August. On 24 August, the Red Army entered Pyongyang and established a military government over Korea north of the parallel. American forces landed in the south on 8 September and established the US Army Military Government in Korea.
