The Ming dynasty (1368â1644), founded by the peasant rebel leader Zhu Yuanzhang (known posthumously as Emperor Taizu), was an imperial dynasty of China. It was the successor to the Yuan dynasty and the predecessor of the short-lived Shun dynasty, which was in turn succeeded by the Qing dynasty. Scholars have traditionally divided Ming history into three distinct periods: Early (1368â1436), Middle (1436â1573), and Late (1573â1644).
Zhu Yuanzhang, the founding emperor of the Ming Dynasty, established his capital in Nanjing (Chinese for southern capital). He ate mostly food cooked with the flavors of South China during his ruling years. His fourth son, Zhu Di, declared himself the emperor in 1403 and gave his reign the title of Yongle.
