Tomb of Huiling, tomb of Emperor Tongzhi of China

The Tongzhi Emperor (27 April 1856 – 12 January 1875), born Zaichun of the Manchu Aisin Gioro clan, was the tenth emperor of the Qing Dynasty, and the eighth Qing emperor to rule over China. His reign, from 1861 to 1875, which effectively lasted through his adolescence, was largely overshadowed by the rule of his mother Empress Dowager Cixi.

Although he had little influence over state affairs, the events of his reign gave rise to what historians call the "Tongzhi Restoration", an unsuccessful attempt to stabilise and modernise China.
