==== Mongol Empire ====
* [[February 9]] &ndash; [[Battle of Sanfengshan]]: The Mongol army (some 50,000 warriors) defeats the Chinese Jin forces near [[Yuzhou, Henan|Yuzhou]]. General [[Subutai]] successfully wipes out the last field army of the [[Jin dynasty (1115–1234)|Jin dynasty]] – therefore sealing its fate of falling to the [[Mongol Empire]]. During the encounter, also called the Battle of the Three-Peak Mountain, Emperor [[Emperor Aizong of Jin|Aizong of Jin]] orders the Jin army (some 150,000 men) to intercept the Mongols. The Jin soldiers are constantly harassed by small groups of Mongol cavalry on the way. When they arrive at Sanfeng Mountain, the Jin army is hungry and exhausted by heavy snowfall. The Jin forces are quickly defeated by the Mongols and flee in all directions.
* [[April 8]] &ndash; [[Mongol conquest of the Jin dynasty|Mongol–Jin War]]: The Mongol army led by [[Ögedei Khan]] and his brother [[Tolui]] begins the [[Siege of Kaifeng (1232)]], capital of the Chinese Jin dynasty. During the summer, the [[Jurchen people|Jurchens]] try to end the siege by negotiating a peace treaty, but the assassination of a Mongol embassy makes further talks impossible. While the negotiations are going on, a plague is devastating the population of the city. In the meantime, supplies stored at Kaifeng are running out, and several residents of the city are executed on the suspicion that they are traitors.<ref>Franke, Herbert (1994).

* June &ndash; [[Mongol invasions of Korea|Mongol invasion of Korea]]: [[Choe Woo]], Korean military dictator of [[Goryeo]], orders against the pleas of King [[Gojong of Goryeo|Gojong]] and his senior officials, the royal court, and most of [[Kaesong|Songdo]]'s population to be moved to [[Ganghwa Island]]. Woo starts the construction of strong defenses on Ganghwa Island, which becomes a fortress. The government orders the common people to flee the countryside and take refuge in major cities, mountain citadels, or nearby islands. The Mongols occupy much of northern [[Korea]], but fail to capture Ganghwa Island.
* [[December 16]] &ndash; [[Battle of Cheoin]]: Korean forces defeat a Mongol attack at Cheoin (modern-day [[Yongin]]). The Mongol Empire concludes a peace treaty with Goryeo and withdraws its forces.
