The Saka were a group of nomadic Eastern Iranian peoples who historically inhabited the northern and eastern Eurasian Steppe and the Tarim Basin. The Sakas were closely related to the Scythians, and both groups formed part of the wider Scythian cultures, through which they ultimately derived from the earlier Andronovo, Sintashta and Srubnaya cultures, with secondary influence from the BMAC, and since the Iron Age, also East Asian genetic influx, with the Saka language forming part of the Scythian phylum, one of the Eastern Iranian languages.
