Nguyễn Huệ
The actions of Lê Chiêu Thống and the Qing invasion gave Nguyễn Huệ a good chance to officially take the throne and gain popularity among northern Vietnamese people. On 22 December 1788, Nguyễn Huệ proclaimed himself emperor Quang Trung and formally declared that the Lê dynasty had ended. He then led an army march north. Although the Tây Sơn army was smaller, they defeated the unprepared Qing troops in a series of battles during the 1789 Lunar New Year celebration and forced the rest of Qing army to flee in confusion. Lê Chiêu Thống fled to China which marked the end of the Lê dynasty.
