Shunten

Shunten was the legendary first king of Chūzan and a ruler of Okinawa. The official histories of the Ryukyu Kingdom claim that he was the son of the samurai Minamoto no Tametomo and a local noblewoman during his exile following the Hōgen rebellion. He became the aji of Urasoe at age 15. Seven years later, he led a popular revolt against Riyū, who had usurped the throne of the ancient and mythical Tenson dynasty. He gained recognition as the overlord of all Okinawan chieftains, ruling from Urasoe Castle until his death in 1237. He inaugurated the Shunten dynasty, which lasted until 1260, when his grandson Gihon disappeared.
