尚泰王
Until the late 19th century, both Qing China and the Satsuma Domain had claimed the Ryūkyū Kingdom as a tributary state. In the 1870s, the Japanese government maneuvered to establish direct sovereignty over the Ryūkyū Islands. As part of a settlement with Qing government after the 1874 Japanese incursion into Taiwan, the Qing government renounced its claims, clearing the way for direct Japanese rule. The Ryūkyū King Shō Tai was declared a vassal of the Meiji court and his kingdom designated Ryukyu-han (琉球藩), or the feudal domain of Ryukyu. During the first years of Japanese control, King Shō Tai retained nominal authority, but Ryukyu was largely ruled by the Naimushō office in Naha. In 1879, the Japanese government tightened control over Ryukyu, forcing the King to withdraw and declaring Ryukyu a prefecture (Okinawa-ken 沖縄県).
