abstract:Nanzan (南山), sometimes called Sannan (山南), was one of three kingdoms which controlled Okinawa in the 14th century. Okinawa, previously controlled by a number of local chieftains or lords, loosely bound by a paramount chieftain or king of the entire island, split into these three more solidly defined kingdoms within a few years after 1314; the Sanzan period thus began, and would end roughly one hundred years later, when Chūzan's King Shō HashiTechnically, Hashi's father Shō Shishō was king of Chūzan in 1419, and neither was called "Shō" until that name was granted them by the Ming court in 1421.
