Sieges of Zhongdu

The Sieges of Zhongdu took place in 1214 and 1215 during the Mongol conquest of the Jin dynasty. Zhongdu, the capital of the Jin dynasty and located in present-day Beijing, was progressively isolated by the forces of the Mongol Empire under Genghis Khan. After earlier Mongol incursions and the relocation of the Jin court to Kaifeng, the city endured prolonged blockade and famine before surrendering in June 1215.
