Khamag Mongol was a major Mongolictribal confederation on the Mongolian Plateau in the 12th century. It is sometimes considered a be a predecessor state to the Mongol Empire. The existence of a somewhat mysterious tribal power known in Mongol tradition as Khamag Mongol Uls is recorded in sources of Khitan Liao dynasty in North China and eastern Mongolia. After the fall of Liao dynasty in 1125, the Khamag Mongols began to play an important role on the Mongolian plains. They occupied one of the most fertile lands of the country, the basins of the riverOnon, Kherlen and Tuul Rivers in the Khentii Mountains. The Taichiud was one of the three core tribes in the Khamag Mongol Khanate of Mongolia during the 12th century and whose people lived in the southern part of Siberia's Zabaykalsky Krai. Zabaykalsky Krai and the Mongolian Khentii Province were core regions of the Khamag Mongol Khanate. The Khamags consisted of the three core clans Khiyad, Taichuud, Jalairs. The first khan of Khamag Mongol recorded in history is Khabul Khan from the Borjigin clan. Khabul Khan successfully repelled the invasions of the Jurchen Jin armies. Khabul Khan was succeeded by Ambaghai Khagann of the Taichiud. Ambagai was captured by the Tatar confederation while delivering his daughter for marriage to their leadership. He was handed over to the Jin, who cruelly executed him. Ambaghai was succeeded by Hotula Khan, a son of Khabul Khan. Hotula Khan engaged the Tatars in 13 battles in an effort to obtain vengeance for the death of Ambagai Khan. Khamag Mongol was unable to elect a khan after Hotula died. However, Khabul's grandson Yesugei, who was a chief of the Khiyad tribe, was an effective and preeminent leader of Khamag Mongol. Temujin, the futureGenghis Khan, was born into Yesugei's family as the first son in Delüün Boldog on the upper reaches of the Onon river in 1162. When young Tooril Khan asked for help from Yesugei, the ruler of the Khamag Mongol, to dethrone his brothers among the Keraites, the Mongols helped him defeat the Keraite leaders and put him on the throne in the early 12th century. Yesugei was poisoned by the Tatars in 1170 and shortly after Yesugei died. The Khamag Mongol began to disintegrate after Yesugei's death in 1171. Political anarchy and a power vacuum lasted until 1189 when Temujin became the Khan of the Khamag Mongol. War broke soon out between other Mongol tribes. Temujin's friend Jamukha was recognized by the rival tribes as Gur-Khan in 1201 but he was defeated by the alliance of Khamag Mongol and Keraites. When Tooril Khan refused to cement the alliance with the Khamag, Temujin's wars with the clans nearly destroyed him. Temujin united all clans on the Mongolian plateau at last in 1206, when he was given the title Genghis Khan.
