Lê Chiêu Thống
Lê Chiêu Thống (1765–1793), born Lê Duy Khiêm and later Lê Duy Kỳ, was the last emperor of the Vietnamese Lê dynasty. He was overthrown by the Tây Sơn dynasty. He appealed to the Qing dynasty of China to help regain the throne but failed after losing the Battle of Ngọc Hồi-Đống Đa. Afterwards, he no longer received support from the Qing emperor, relatives of the Lê family were imprisoned in Vietnam, and he died in China.
