库苏古尔省
One of the earliest mentions of the Oirat people in a historical text can be found in "The Secret History of the Mongols", the 13th century chronicle of Genghis Khan's rise to power. In the Secret History, the Oirats are counted among the "forest people" and are said to live under the rule of a shaman-chief known as "bäki". They lived in Tuva and Mongolian Khövsgöl Province and the Oirats moved to the south in the 14th century.
