List of ambassadors of Russia to South Korea
This is a List of Ambassadors from Russia to South Korea. The Russian Empire established relations with the Joseon Dynasty in 1884. However Korea was deprived of its right to conduct independent foreign policy by the Japan-Korea Treaty of 1905, while the Union of Soviet Socialist Republics (the eventual successor to the Russian Empire) did not formally recognise Provisional Government of the Republic of Korea in exile. In 1948, three years after the end of Japanese rule in Korea, the USSR recognised only one government on the Korean peninsula—the Democratic People's Republic of Korea, commonly North Korea. In September 1990, towards the end of its existence, the USSR established relations with the Republic of Korea (commonly known as South Korea).
38th parallel north
Japan had occupied the Korean peninsula between 1910 and 1945. When Japan surrendered in August 1945, the 38th parallel was established as the boundary between Soviet and American occupation zones. This parallel divided the Korean peninsula roughly in the middle. In 1948, this parallel became the boundary between the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea), both of which claim to be the government of the whole of Korea. On 25 June 1950, after a series of cross-border raids and gunfire from both the Northern and the Southern sides, the North Korean Army crossed the parallel and invaded South Korea. This sparked a United Nations resolution against the aggression and the Korean War, with United Nations troops (mostly Americans) helping to defend South Korea.
