The Siege of Zhongdu was a major military conflict 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. The Fall of Zhongdu marked a decisive blow to Jin authority in northern China and accelerated the dynasty’s decline.
