context: On 9 August 1945, in the closing days of World War II, the Soviet Union declared war on Japan and advanced into Korea, at the request of the United States. Though the Soviet declaration of war had been agreed by the Allies at the Yalta Conference, the US government had agreed with the Russian government earlier that the Soviet advance would stop at the 38th parallel, which it did. The US government forces arrived a few weeks later and occupied the area south of the 38th parallel, including the capital, Seoul. This was incorporated into General Order No. 1 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 United States Army Military Government in Korea.
