Ибн Хордадбех
In the 9th century Ibn Khordadbeh indicated that they held autonomy within the Kimek confederation. They entered the Kimek in the 8th- or beginning of 9th century, and were one of the seven original tribes. In the 10th-century's "Hudud al-'Alam" it is said that the Kimek appointed the Kipchak king.
