غجا جوسون
According to Sin Chaeho's Joseon Sangosa, Beonjoseon began disintegrating after its king had been killed by a rebel from the Chinese state of Yan at around 323 BC. With this, the five ministers of Beonjoseon began contending for the throne. Gihu joined in this struggle, and emerged victorious as the new king of Beonjoseon, defeating the competitors for the throne. He established Gija Joseon, named after his ancestor Gija. During Gija Joseon, the king enjoyed strong sovereign powers. Eventually, in 94 BC, Gija Joseon fell after King Jun was overthrown by Wiman, who established Wiman Joseon in its place.
