Khamag Mongol (Mongolian: ᠬᠠᠮᠤᠭ
ᠮᠣᠩᠭᠣᠯ Хамаг Монгол, lit. 'Whole Mongol'; Chinese: 蒙兀國) was a loose Mongolic tribal confederation on the Mongolian Plateau in the 12th century. It is sometimes considered to 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 the Khitan-led Liao dynasty. After the fall of the 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 river Onon, Kherlen and Tuul Rivers in the Khentii Mountains. The Taichiud (Cyrillic: Тайчууд) 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 modern-day Zabaykalsky Krai. The present-day Zabaykalsky Krai and the Khentii Province of Mongolia were the core regions of the Khamag Mongol Khanate. The Khamags consisted of the three core clans Khiyad, Taichuud, and Jalairs.
