The Kara-Khanid Khanate, also known as the Karakhanids, Qarakhanids, Ilek Khanids or the Afrasiabids, was a Karluk Turkic khanate that ruled Central Asia from the 9th to the early 13th century. The dynastic names of Karakhanids and Ilek Khanids refer to royal titles with Kara Khagan being the most important Turkic title up until the end of the dynasty.
