Shō Shin
The reign of Shō Shin also saw the expansion of the kingdom's control over several of the outlying Ryukyu Islands. Okinawan ships began in the late 15th century to frequent Miyakojima and the Yaeyama Islands; following a series of disputes among the local lords in the Yaeyama Islands which broke out in 1486, Shō Shin in 1500 sent military forces to quell the disputes and establish control over the islands. Kumejima was brought under firm control of Shuri, and liaison offices were established in Miyako and Yaeyama, in 1500 and 1524 respectively.
