Kara-Khanid Khanate
Turkic speakers probably settled the Amu Darya, Syr Darya and Zarafshan river basins from at least 600–700 CE, gradually ousting or assimilating the speakers of Eastern Iranian languages who previously inhabited Sogdia, Bactria and Khwarezm. The first Turkic dynasty in the region was that of the Kara-Khanid Khanate in the 9th–12th centuries, who were a confederation of Karluks, Chigils, Yaghma and other tribes.
