Zhu Yuanzhang proclaims himself the Hongwu Emperor, beginning the Ming dynasty.

The Hongwu Emperor, also known by his temple name as the Emperor Taizu of Ming, personal name Zhu Yuanzhang, courtesy name Guorui, was the founding emperor of the Ming dynasty, reigning from 1368 to 1398.

The Ming dynasty, officially the Great Ming, was an imperial dynasty of China that ruled from 1368 to 1644, following the collapse of the Mongol-led Yuan dynasty. The Ming was the last imperial dynasty of China ruled by the Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng, numerous rump regimes ruled by remnants of the Ming imperial family, collectively called the Southern Ming, survived until 1662.
