History of South Korea
The history of South Korea formally begins with its establishment on August 15, 1948.
Day of the Foundation of the Republic (North Korea)
Following the Liberation of Korea in 1945 by the Soviet and American forces, a communist Soviet military regime was set up in the northern part of Korea. A new Supreme People's Assembly was elected in August 1948, and on 3 September a new constitution was promulgated. The Democratic People's Republic of Korea was proclaimed on 9 September, with Kim Il-sung as Premier. Because the date is 9 September, it is also called 9 · 9 (old version).
