Chongzhen Emperor
The Manchus were quick to exploit the death of the Chongzhen Emperor: by claiming to "avenge the emperor," they rallied support from loyalist Ming forces and civilians. The Shun dynasty lasted less than a year with Li Zicheng's defeat at the Battle of Shanhai Pass. The victorious Manchus established the Shunzhi Emperor of the Qing dynasty as ruler of all China. Because the Chongzhen Emperor had refused to move the court south to Nanjing, the new Qing government was able to take over a largely intact Beijing bureaucracy, aiding their efforts to displace the Ming.
