Wiman Joseon
Wiman Joseon (194–108 BC) was part of the Gojoseon period of ancient Korean history. It began with Wiman's seizure of the throne from Gojoseon's King Jun and ended with the death of King Ugeo who was a grandson of Wiman. Apart from archaeological data, the main source on this period of Korean history comes from chapter 115 of Sima Qian's "Shiji" (Records of the Grand Historian). Wiman was originally a military leader from the Kingdom of Yan under the Han dynasty.
