琉球民族
During the period when Ryukyu was controlled by the Shimazu clan of Japan (1603-1868), the people of Kumemura came to serve an even more direct role in government and in diplomacy, at least initially. Ryukyu's strong connections to China were crucial for Japan, and were contingent upon China's ignorance of Ryukyu's subordination. Thus, the people of Kumemura served not only in the royal government, and as diplomats, but also as cultural agents. The Ryukyuan people were forbidden to speak Japanese, to wear Japanese clothes, or, in a variety of other ways, to reveal the Japanese influence upon them. Thus, the magistrate of the Kumemura community took on an unofficial role comparable to a minister of education, and the Ryukyuan people, even more so than before, were exposed to a campaign of both passive and active Sinification.
