Khwarezmid Empire
The Khwarazmian Empire, or simply Khwarazm, was a culturally Persianate, Sunni Muslim empire of Turkic mamluk origin, ruled by the Anushtegin dynasty. The Khwarazmian Empire ruled large parts of present-day Central Asia, Afghanistan, and Iran from 1077 to 1231; first as vassals of the Seljuk Empire and the Qara Khitai, and from circa 1190 as independent rulers up until the Mongol invasion in 1219–1221.
