Nanzan
The political entity was identified as a tiny country,[1][2][3] a kingdom, or a principality by modern historians, however the ruler of Nanzan was in fact not "kings" at all, but petty lords with their own retainers owing their direct service, and their own estates.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 Hashi[4] conquered Hokuzan in 1419 and Nanzan in 1429.Around 1381, a Nanzan envoy was severely reprimanded for bringing silver into China with which he intended to purchase porcelains for his own personal material gain.In the 1390s, the kings of all three kingdoms died within a few years, and succession disputes erupted across the island; similar events occurred in Nanking at the same time, with the death of the Hongwu Emperor in 1398.At the end of the 17th century, Sannan nominally comprised 15 magiri (間切): Mawashi, Haebaru, Kochinda, Ōzato, Sashiki, Chinen, Tamagusuku, Mabuni, Gushichan, Kyan, Makabe, Takamine, Kanegusuku, Oroku, and Tomigusuku.
