The Guangxu Emperor (14 August 1871 â 14 November 1908), personal name Zaitian (Manchu: Dzai-Tiyan), was the eleventh emperor of the Qing dynasty, and the ninth Qing emperor to rule over China. His reign lasted from 1875 to 1908, but in practice he ruled, under Empress Dowager Cixi's influence, only from 1889 to 1898.
These changes were opposed by the conservatives, led by Empress Dowager Cixi, who was the real power behind the ineffectual Guangxu. She forced Guangxu into house arrest, and arrested and executed six chief proponents of the Hundred Daysâ Reform, known as the âSix Gentlemen.â.
