Seii

Seii (1328–1349), fifth and last king of the Eiso dynasty of Chūzan, is known from the Ryukyuan royal chronicles. He succeeded his father Tamagusuku in 1337 at about ten years of age, and his mother ran the government in his name. The chronicles condemn her rule in a line: the hen crows in place of the cock.

Meanwhile Satto, the aji of Urasoe, won standing among the aji for his virtue. When Seii died in 1349, the regional lords set aside his heir and enthroned Satto, ending Eiso rule.
