Kublai’s father Tolui would serve as regent for two years until Genghis’ successor, Kublai’s third uncle Ogedei, was enthroned as Khagan in 1229. After the Mongol conquest of the Jin dynasty, in 1236, Ogedei gave Hebei (attached with 80,000 households) to the family of Tolui, who died in 1232. Kublai received an estate of his own, which included 10,000 households. Because he was inexperienced, Kublai allowed local officials free rein.
