Yongle Emperor
Zhu Yuanzhang won his fight with the Yuan and became the Hongwu Emperor of China in 1368. He called his new government the Ming. The Ming had rules about who should be the new emperor when the old emperor died. Zhu Biao () was Zhu Yuanzhang's oldest son and people thought he would be the next emperor. Zhu Di was only the 4th son, so people did not think he would become the next emperor. He was still very important, though. The Hongwu Emperor made him the leader of Beiping (today's Beijing and the area around it).
