History of Korea
After the end of WWII in 1945, the Allies divided the country into a northern area (protected by the Soviets) and a southern area protected (primarily by the United States). In 1948, when the powers failed to agree on the formation of a single government, this partition became the modern states of North and South Korea. The peninsula was divided at the 38th Parallel: the "Republic of Korea" was created in the south, with the backing of the US and Western Europe, and the "Democratic People's Republic of Korea" in the north, with the backing of the Soviets and the communist People's Republic of China. The new premier of North Korea, Kim il-Sung, launched the Korean War in 1950 in an attempt to reunify the country under Communist rule. After immense material and human destruction, the conflict ended with a cease-fire in 1953. The two nations officially remain at war because a peace treaty was never signed. In 1991, both states were accepted into the United Nations.
Demographics of North Korea
According to "The World Factbook", North Korea is racially homogeneous and contains a small Chinese community and a few ethnic Japanese. The 2008 census listed two nationalities: Korean (%) and Other (%). Korea was annexed by the Empire of Japan in 1910, in which the Korean Peninsula was occupied by Japanese. In 1945, when Japan was defeated in World War II, Korea was divided into two occupied zones: North occupied by the Soviet Union and the South by the United States. Negotiations on unification failed, and in 1948 two separate countries were formed: North and South Korea.
