Shō Hashi

Shō Hashi (1372–1439) was a king of Chūzan, one of three tributary states to China on the western Pacific island of Okinawa. He is traditionally described as the unifier of Okinawa and the founder of the Ryukyu Kingdom. He was the son of the lord Shishō of the First Shō dynasty. Modern scholarship has connected Shishō's potential father, Samekawa, to a family of Southern Court-affiliated seafarers from the island of Kyushu, where Hashi was possibly born. Hashi became the lord of Sashiki Castle in southern Okinawa in 1392, becoming a noted military leader. In 1407, following a diplomatic incident between the Chūzan king Bunei and the Ming dynasty court, Shishō took the throne, attributed by the Ryukyuan official histories to a coup d'état by Hashi to install his father as king.

Hashi himself became king of Chūzan following Shishō's death. He continued tributary and trade relations with the Ming and embarked on military campaigns against the rival kingdoms of Sannan and Sanhoku. By 1430, he was the sole Ming tributary in Okinawa. He likely lacked territorial control over the island, limited to trade hegemony over the region within the Ming tribute system. He erected the earliest inscribed stele in Okinawa at Shuri Castle in 1427. He died in 1439 and was buried in a cave tomb near Shuri. His death began a period of rapid succession between his sons and grandsons, and eventually the kingship of Shō Taikyū.
