Ögedei named a grandson as heir, two widows put other men on the throne, and Möngke executed the grandson's mother for sorcery

The Yuan History records that Ögedei Khan named his grandson Shiremün as heir. Ögedei died in 1241 after a night of drinking. His widow Töregene ruled from 1242 and had their son Güyük enthroned in 1246. Güyük died in 1248, and his widow, Oghul Qaimish, held the regency. At an assembly called by Batu, Genghis Khan's grandson through Jochi, Batu proposed Möngke, eldest son of Tolui. Oghul Qaimish's envoy Bala objected that Ögedei had named Shiremün before all the princes. Möngke's brother Möge replied that her own party had broken Ögedei's order by choosing Güyük. Bala had no answer. In the sixth month of 1251 a second assembly enthroned Möngke on the Onon River. Shiremün and his brothers objected, and Möngke sent troops to watch them. In 1252 he scattered the Ögedeid princes to distant lands, divided the household wealth of Ögedei's widows among other princes, and put Güyük's widow and Shiremün's mother to death for sorcery. Shiremün was exiled. Ögedei's grandson Qaidu, sent to Qayaliq that year, later led the Ögedeid house in wars against Möngke's brother Kublai^†.
