Descendants of the first Ming emperor were made princes and given (typically nominal) military commands, annual stipends, and large estates. The title used was "king" (, "wáng") but – unlike the princes in the Han and Jin dynasties – these estates were not feudatories, the princes did not serve any administrative function, and they partook in military affairs only during the reigns of the first two emperors. The rebellion of the Prince of Yan was justified in part as upholding the rights of the princes, but once the Yongle Emperor was enthroned, he continued his nephew's policy of disarming his brothers and moved their fiefs away from the militarized northern border. Although princes served no organ of state administration, the princes, consorts of the imperial princesses, and ennobled relatives did staff the Imperial Clan Court, which supervised the imperial genealogy.
