清末新政
In the early 20th century, the late Qing government encouraged Han Chinese colonization of Mongolian lands under the name of "New Policies" or "New Administration" (xinzheng). As a result, some Mongol leaders (especially those of Outer Mongolia) decided to seek Mongolian independence. After the Xinhai Revolution, the Mongolian Revolution on 30 November 1911 in Outer Mongolia ended an over 200-year rule of the Qing dynasty.
