Korean history - Gojoseon, the first state of Korea

Gojoeseon was the first state of Korea. It was established in 2333 B.C. The history of Gojoseon distorted by Japanese scholars during the Japanese Occupation Period(1910-1945) and this distorted history was introduced to the World as the true history. However, many relics were discovered and the Gojoseon's history was recovered as true history.
