Wiman of Gojoseon

Wiman or Wei Man was a refugee from the Han Dynasty state of Yan who established a kingdom in north-western Korea in the 2nd century BC. He was the first ruler in the history of Korea to have been recorded in documents from the same time period.

Biography
After the founding of the Han Dynasty in China, there was a time of political insurrection, with populations seeking refuge eastwards. Wiman was said to have been one of these refugees, reported to have led over a thousand followers (dressed in Joseon style and he himself wearing his hair in a different topknot) to Gojoseon. He was initially ordered to fortify Gojoseon's northwestern border by King Jun of Gojoseon, however by solidifying power over the Yan refugees, Wiman ursurped the throne and claimed kingship (194~180 BC). King Jun is said to have sought refugee in Jin state and called himself the "King of Han."

Wiman's capital of Gojoseon was Wanggeom-seong, generally identified as Pyongyang. Since the Han Dynasty was not completely stabilized yet, the Governor of Liaodong appointed Wiman as an outer subject, provided that he did not prevent natives going up to the empire. The appointment is dated at 191 or 192 BCE. Having superior military strength, Wiman Joseon was able to subjugate the State of Jinbeon (진번, 眞番) and Imdun (임둔, 臨屯), vastly extending its borders. His kingdom was eventually conquered by Emperor Wu of Han in 108 BC during the reign of his grandson King Ugeo.
