Kaidu

Kaidu (c. 1235–1301), a posthumous son of Qashi and grandson of Ögedei Khan, led the House of Ögedei. In 1252 Möngke enfeoffed him at Qayaliq. He defeated the Chagatai khan Baraq and divided Transoxiana with him at the Talas kurultai of 1269, and in 1271 became ruler of the reconstituted Ulus of Ögedei.

From 1282 he controlled the Chagatai khan Duwa and waged decades of war against Kublai's Yuan dynasty. Wounded fighting Qayishan at Mount Tiejiangu in September 1301, he died late that year.
