Sanzan period

Period in Okinawan history

The Sanzan period is a period in the history of the Okinawa Islands when three lines of kings, namely Sanhoku , Chūzan and Sannan , are said to have co-existed on Okinawa Island. It is said to have started during King Tamagusuku's reign and, according to Sai On's edition of the Chūzan Seifu (1725), ended in 1429 when Shō Hashi unified the island. Historical records of the period are fragmentary and mutually conflicting. Some even question the co-existence of the three polities.
