The House of Ögedei, sometimes called the Ögedeids, was an influential Mongol family and a cadet branch of the Borjigin clan from the 12th to 14th centuries: having been descended from Ögedei Khan (1186-1241) who was the third son and successor of Genghis Khan (1162-1227) that continued the expansion of the Mongol Empire far beyond the East Asian homeland of the Mongols.
When, after the Toluid Möngke Khan's death, the Mongol Empire disintegrated into civil war, the members of the House of Ögedei were influential players in the politics of the region. Among the lines of Genghis Khan's sons — Ögedei, Jochi, Chagatai, and Tolui, the House of Ögedei tended to ally with the Chagataids (descendants of Chagatai) against the House of Jochi, while seeking control for themselves within the Chagatai Khanate at first. The Ögedeids also allied with the Golden Horde against the Yuan founding emperor Kublai (son of Tolui), who was allied with his brother Hulagu, leader of the Ilkhanate in Persia. The Ögedeids attempted to unite the Mongol Empire under their own rule, and Ögedeid princes continued to march against the Yuan dynasty well into the 14th century, such as during the Kaidu–Kublai war.
