Shortly after the withdrawal of the Mongols and Kory 's support of the Ming, the latter moved to establish a commandery on Kory soil. Korean armies set out to attack, but one commander, Yi S nggye (133998), refused to go along and took control of the government himself. The next year he placed a Kory king on the throne and began wide-ranging land reform, supported by the rising scholar-official class. Land reform entailed a thorough cadastral survey (1390); all land registers were abolished, and all lands reverted to the state. Two years later, Kory fell, to be replaced when Yi S nggye assumed the throne of the Yi dynasty. | 1 |
