I want to know the answer to the following question:
When did Beijing lose to Li Zicheng's rebel forces and the Manchu-led Qing dynasty?
All the background I'm provided with is that "After the fall of Beijing to Li Zicheng's rebel forces and then to the Manchu-led Qing dynasty in the spring of 1644, the Ming prince Zhu Yousong was enthroned in Nanjing in June 1644 as the Hongguang Emperor.". Is that enough to answer the question?
Answer: yes
