Shō Hashi
Shō Hashi, the virtual founder of the First Shō Dynasty, overthrew Bunei in 1406. He installed his father Shō Shishō as the nominal King of Chūzan. Shō Hashi annihilated the King of Hokuzan (Sanhoku) in 1416. In 1421, after the death of his father, Shō Hashi became the King of Chūzan. He overthrew the King of Nanzan (Sannan) until 1429, unifying the island. The surname Shō (尚) was given by the Ming emperor.
