Wokuotai khanate was a fief given to Wokuotai by Genghis Khan, and it was also a Mongolian khanate established by Wang Haidu after Wokuotai. The purpose of Genghis Khan's enfeoffment of Wokuotai khanate to Wokuotai was to pave the way for the special identity of the crown prince of Wokuotai and to become a Mongolian khan in the future. The enfeoffment of Wokuotai khanate was a fief given to Wokuotai after Genghis Khan's Western Expedition 1225. It was only used for grazing before boarding the khanate, and it was also a manifestation of clan tradition (all sons had the right to obtain membership), which was quite different from the other three sons in nature.
Historians have proved that, as Khan, Wokuotai will be the owner and manager of Mongolian territory, whose residence is in the capital, Haci and Lin, and he is also the only person who has the right to enfeoffment the newly conquered territory. Therefore, there is no need to worry about the living space of his descendants. After Wokuotai acceded to the throne, he gave Ye Mili's seal to his eldest son, Gui You, and his second son, Kuan Duan, to Liangzhou (Wuwei, Gansu), and transferred 3,000 Mongolian herders to Kuo Duan's name. Genghis Khan gave it to Tuo Lei's Snow Department and Suledu Department before his death. Kuo Duan was sealed in Hexi, which clearly shows that Wokuotai didn't get a fief with an area equal to his brother's, and the fief of Wokuotai was not a complete area. In the era of Taizong (Wokuotai) and Dingzong (Gui You, the son of Wokuotai), although many Wokuotai kings held high positions and held military power, when Meng Ge (the eldest son of Tuo Lei) ascended the throne in 125 1 year, he found that there was no unified political entity to rely on. On the grounds of plotting a coup, Mongo severely cracked down on Wokuotai forces, exiled the king's brains and lost his life; Seize the army belonging to Khan and the armed forces formed by the kings of various ministries; Kings moved to different places: Jimsar, Erqis River and Emin, Mongols were all in Yongchang, Hexi, and Haidu was moved to Hai 'anli.
