(Ilek-khans), a Muslim Turkic dynasty of the Karakhanid state in Middle Asia from 927 to 1212. Named after the first khan, Abdulkarim Satuk Karakhan (died 955 or 956).
The family descended from the Iagma tribe and bore the title of bogra-khan. At the head of the Karakhanids stood the tamgachkhan, or khan of khans. The most powerful representatives of the Karakhanids were Nasr (late tenth century), Ibrahim (1046/47–1068), and Arslan (1102–30). The last Karakhanid, Klych-Arslan ibn Klych, was killed in 1212 by the shah of Khorezm, Muhammad.
