He was originally enfeoffed as the Prince of Yan (燕 王) in May 1370, with the capital of his princedom at Beiping (modern Beijing). Amid the continuing struggle against the Mongols of the Northern Yuan dynasty, Zhu Di consolidated his own power and eliminated rivals such as the general Lan Yu . He initially accepted his father's appointment of his eldest brother Zhu Biao and then his nephew Zhu Yunwen as crown prince, but when Zhu Yunwen ascended the throne as the Jianwen Emperor and began executing and demoting his powerful uncles, Zhu Di found pretext for rising in rebellion against his nephew . Assisted in large part by eunuchs mistreated by the Hongwu and Jianwen Emperors, who both favored the Confucian scholar - bureaucrats, Zhu Di survived the initial attacks on his princedom and drove south to launch the Jingnan Campaign against the Jianwen Emperor in Nanjing . In 1402, he successfully overthrew his nephew and occupied the imperial capital, Nanjing, after which he was proclaimed Emperor and adopted the era name Yongle, which means "perpetual happiness". </P>
