The Empire of China, also known in historiography as the Hongxian Monarchy, was a short-lived attempt by Chinese president Yuan Shikai from late 1915 to early 1916 to reinstate the monarchy in China, with himself as emperor. The attempt ultimately failed, set back the republican cause by several years, and led China into a period of fracture and conflict among various local warlords.

Puyi was the last emperor of China, reigning as the eleventh and final monarch of the Qing dynasty. He became emperor at the age of two in 1908, but was forced to abdicate in 1912 as a result of Xinhai Revolution at the age of six. During his first reign, he was known as the Xuantong Emperor, with his era name meaning "proclamation of unity".
