Iranian peoples
During pre-Islamic and early Islamic times, southern Central Asia was inhabited predominantly by speakers of Iranian languages. Among the ancient sedentary Iranian peoples, the Sogdians and Chorasmians played an important role, while Iranian peoples such as Scythians and the later on Alans lived a nomadic or semi-nomadic lifestyle. The well-preserved Tarim mummies with Caucasoid features have been found in the Tarim Basin.
