History of South Korea
The history of South Korea formally begins with its establishment on August 15, 1948.
North Korea–Russia relations
Diplomatic relations between North Korea (Democratic People's Republic of Korea, DPRK) and the Soviet Union (Union of Soviet Socialist Republics, USSR, the predecessor state to the Russian Federation) were first established on October 12, 1948 shortly after the Democratic People's Republic of Korea was proclaimed. During the Korean War, the Korean People's Army was supported by the Soviet military forces. North Korea was founded as part of the Communist bloc, and received major Russian support. China and the Soviet Union competed for influence in North Korea during the Sino-Soviet split in the 1960s, as the North Korea tried to maintain good relations with both countries.
