Dodo was the fifteenth son of Nurhaci and one of Dorgon's two full brothers. He distinguished himself in the conquest of China alongside Dorgon. Dodo is also somewhat notorious due to his sanctioning of the Massacre of Yangzhou, a terrible bloodbath in which an alleged 800,000 men, women, and children were killed by Manchu soldiers. This massacre began when Dodo authorized his men to have five days to do anything they wished to the town of Yangzhou's inhabitants. Dodo was created Prince Yu of the First Rank in 1644. In 1646, he led a military campaign into Mongolia and emerged victorious. He was then made Co-regent by his brother Prince Regent Dorgon, in place of their older cousin, Jirgalang Prince Zheng. Dodo died of smallpox in 1649, aged 36. After the death of Dorgon, the Shunzhi Emperor posthumously stripped Dodo of his titles.
