Shō Hashi
The son of Shishō was Shō Hashi, who is known as the first king of the Ryukyu Kingdom. Shō Hashi overthrew chief Bunei of Chūzan in 1406 and installed his father as king. His kingship was acknowledged by the Yongle Emperor of China, who caused a diplomatic mission to be sent to the Ryukyuan capital in 1415. He was retroactively given the surname (Shang in Chinese) when the Emperor bestowed the name to Shō Hashi.
