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).
Public holidays in South Korea
These days celebrate events considered joyous to Korea. In the beginning, Independence Declaration Day (March 1) was first stipulated in 1946. After the establishment of the Government of the Republic of Korea in 1948, four major National Celebration Days (Independence Declaration Day, Constitution Day, Liberation Day, National Foundation Day) were provided by "The Law Concerning the National Celebration Days" (국경일에관한법률) in 1949. 
In 2005, Hangul Day became the 5th National Celebration day.
