After the Mongol conquest of the Jin Empire (1211–1234), Huining Prefecture was abandoned. In the 17th century, the Manchus used building materials from Huining Prefecture to construct their new stronghold in Alchuka. The region of Harbin remained largely rural until the 1800s, with over ten villages and about 30,000 people in the city's present-day urban districts by the end of the 19th century.
