Tamagusuku

According to Ryukyu's official history, Okinawa was split into three polities during the reign of Tamagusuku.

Succeeding his father Eiji as paramount chief of Okinawa's territorial lords at the age of nineteen, Tamagusuku lacked the charisma and leadership skills to command respect and loyalty from those lords (the anji).

His failure to institute reforms or innovations in governance is generally claimed as one of the causes of the fall of the dynasty, which ended with Tamagusuku's son and successor Seii.

[2] The Aji of Ōzato fled south from Tamagusuku's capital at Urasoe and, along with his followers, became the King of Nanzan.

[3] The Lord of Nakijin, based some distance to the north, declared himself King of Hokuzan.
