Aisin Gioro is the name of the imperial clan of Manchu emperors of the Qing dynasty. The House of Aisin Gioro ruled China from 1644 until the Xinhai Revolution of 1911-12, which established a republican government in its place. The word aisin means gold in the Manchu language, and "gioro" is the name of the Aisin Gioro's ancestral home in present-day Yilan, Heilongjiang Province. In Manchu custom, families are identified first by their hala (哈拉), i.e. their family or clan name, and then by mukūn (穆昆), the more detailed classification, typically referring to individual families. In the case of Aisin Gioro, Aisin is the mukūn, and Gioro is the hala. Other members of the Gioro clan include Irgen Gioro (伊爾根覺羅), Susu Gioro (舒舒覺羅) and Sirin Gioro (西林覺羅).
