History of Korea/Gojoseon Empire

Gojoseon was an ancient Korean kingdom.

It is said to have been founded in 2333 BC by Dangun Wanggeom. Archaeological evidence of a Gojoseon-era civilization is found in the transition from the Jeulmun pottery to the Mumun pottery around 1500 BC, when groups of semi-sedentary small-scale agriculturalists occupied most of the Korean Peninsula.

During its early phase, the capital of Gojoseon was located in Liaoning; around 400 BC, and was moved to Pyongyang, while in the south of the peninsula, the Jin state arose by the 3rd century BC.

The territory of Gojoseon was invaded by the Han Dynasty of China during the Gojoseon–Han War in 108 BC, which is said to have led to the collapse of the kingdom into many small states, until the Proto–Three Kingdoms emerged and marked their own period in Korean history.

The people of the Gojoseon-territory are referred to in Chinese records as Dongyi "eastern barbarians." Their language was probably a predecessor of the equally prehistoric Buyeo languages, and perhaps a form of Proto-Korean.
