1392 CE
Small domains scattered on Okinawa Island have unified during the fourteenth century into three principalities: Hokuzan (Northern Mountain), Chūzan (Central Mountain) and Nanzan (Southern Mountain).
Hokuzan, which constitutes much of the northern half of the island, is the largest in terms of land area and military strength, but is economically the weakest of the three.
Chūzan lies in the center of the island, and is economically the strongest.
Nanzan constitutes the southern portion of the island.
Its political capital at Shuri, Nanzan is adjacent to the major port of Naha and Kume-mura, the center of traditional Chinese education.
Many Chinese move to Ryukyu to serve the government or to engage in business during this period.
At the request of the Ryukyuan King, the Ming Chinese send thirty-six Chinese families from Fujian to manage oceanic dealings in the kingdom in 1392 during the Hongwu emperor's reign.
Many Ryukyuan officials will descend from these Chinese immigrants, being born in China or having Chinese grandfathers They assist the Ryukyuans in advancing their technology and diplomatic relations.
