Korea
From Halopedia, the Halo wiki
Korea is a country in Northeastern Asia situated on the Korean Peninsula on Earth.
Korea used to be divided into two countries, North Korea and South Korea. This division was not only marked by a Demilitarized Zone (DMZ), but a river and hundreds of unknown land mines as well. During the early 20th Century, Japan took over Korea and held it until 1945, when Korea achieved independence. Then from 1950-53 there was a war called the Korean war in which the Communist North Koreans and Chinese, backed by the Soviet Union, fought the UN which included the South Koreans in 1950 the UN got off to a good start and took over nearly the whole of Korea but in 1951 was terribly beaten and was pushed into a small corner of Korea but in 1953 got the upper hand when the President of America forces China to stop fighting by threatening using the Atomic bomb so without Chinese aid, North Korea was weak and despite USSR aid, the UN forces pushed to Pyongyang. It is speculated that the two countries have came back to form Korea once again. Their capitals are Pyongyang (Northern Korea) and Seoul (Southern Korea). Korea has always been a research powerhouse due to its size and location.
