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".

Throughout Chinese history, "Emperor" was the superlative title held by the monarchs who ruled various imperial dynasties. In traditional Chinese political theory, the emperor was the "Son of Heaven", an autocrat with the divine mandate right to rule all under Heaven. Emperors were worshiped posthumously under an imperial cult. The lineage of emperors descended from a paternal family line constituted a dynasty, and succession in most cases theoretically followed agnatic primogeniture.
