The Mongol invasions of Korea (1231–1259) comprised a series of campaigns between 1231 and 1270 by the Mongol Empire against the Kingdom of Goryeo (the proto-state of modern-day Korea). There were seven major campaigns at tremendous cost to civilian lives throughout the Korean peninsula, ultimately resulting in Korea becoming a vassal state of the Mongol Yuan Dynasty for approximately 80 years.
Fleeing from the Mongols, in 1216 the Khitans invaded Goryeo and defeated the Korean armies multiple times, even reaching the gates of the capital and raiding deep into the south, but were defeated by Korean General Kim Chwi-ryeo who pushed them back north to Pyongan, where the remaining Khitans were finished off by allied Mongol-Goryeo forces in 1219. These Khitans are possibly the origin of the Baekjeong.
Gojong of Goryeo (reigned 1213–1259) was the 23rd king of the Goryeo dynasty of Korea. In 1225, the Mongol Empire demanded tribute goods from Goryeo and the Mongol envoy Chu-ku-yu was killed. His death was used by the Mongols as an excuse to invade Goryeo.
In 1231, Ögedei Khan ordered the invasion of Korea. The experienced Mongol army was placed under the command of General Sartai (not to be confused with Sartaq, a later Mongol khan). The Mongol army crossed the Yalu river and quickly secured the surrender of the border town of Uiju. Choe U mobilized as many soldiers as possible into an army consisting largely of infantry, where it fought the Mongols at both Anju and Kusong. The Mongols took Anju; however, they were forced to retreat after the Siege of Kusong. Frustrated by siege warfare, Sartai instead used his armies' superior mobility to bypass the Goryeo army and succeeded in taking the capital at Gaesong. Elements of the Mongol army reached as far as Chungju in the central Korean peninsula; however, their advance was halted by a slave army led by Ji Gwang-su where his army fought to the death. Realizing that with the fall of the capital Goryeo was unable to resist the Mongol invaders, Goryeo sued for peace. However, Mongols demanded 10,000 otter skins, 20,000 horses, 10,000 bolts of silk, clothing for 1,000,000 soldiers and a large number of children and craftsmen who would become slaves and servants of the Mongol empire. General Sartai began withdrawing his main force to the north in the spring of 1232, leaving seventy-two Mongol administrative officials stationed in various cities in northwestern Goryeo to ensure that Goryeo kept his peace terms.
