Kara-Khanid Khanate
The early 11th century saw a massive Turkic nomadic migration towards the Islamic world. The first waves were recorded in the Kara-Khanid Khanate in 1017–18. It is unknown whether the Cumans conquered the Kipchaks or were simply the leaders of the Kipchak–Turkic tribes. By the 12th century, the two separate confederations of Cumans and Kipchaks merged.
