Notable events during Emperor Lizong's reign included the demise of the Jurchen-led Jin dynasty in 1234, which was obliterated by the joint forces of the Mongol Empire and the Song Dynasty. The Jurchens had fought multiple wars with the Song Empire decades before it was conquered by the Mongols and although their ruler Emperor Aizong tried to make peace with the Song Dynasty to warn them that if the Mongols conquered the Jin Dynasty and they would attack the Song next, Emperor Lizong ignored the warning.
