The Daoguang Emperor (Chinese: 道光帝; pinyin: Dàoguāng Dì; Wade–Giles: Tao4-kuang1 Ti4; Manchu: ᡩᠣᡵᠣ ᡝᠯᡩᡝᠩᡤᡝ, Doro Eldengge Hūwangdi; ᠲᠥᠷᠥ ᠭᠡᠷᠡᠯᠲᠦ, Төр Гэрэлт Хаан; 16 September 1782 – 25 February 1850) was the eighth emperor of the Manchu-led Qing dynasty and the sixth Qing emperor to rule over China, from 1820 to 1850. His reign was marked by "external disaster and internal rebellion," that is, by the First Opium War, and the beginning of the Taiping Rebellion which nearly brought down the dynasty. The historian Jonathan Spence characterizes the Daoguang Emperor as a "well meaning but ineffective man," who promoted officials who "presented a purist view even if they had nothing to say about the domestic and foreign problems surrounding the dynasty."
