The Sakas were the Scythians who lived in the eastern part of Central Asia. They are considered to be of north-eastern Iranian people by modern scholars.[1][2][3] They lived in what is now Kazakhstan, Uzbekistan, Tajikistan, parts of Afghanistan, parts of Pakistan, parts of India and parts of Iran, some of the western portion of China in Khotan, Ukraine, and the Altay Mountains and Siberia in Russia, in the centuries before 300.

Saka is the usual Persian term, while Scythian is a Greek term. Some of their neighbours included the Sarmatians, Issedones and Massagetae. Their language is poorly known, but seems to have originally been a member of the Iranian family (though some question whether this applied to all strata of their society, or only the ruling class at various times). They were known to the Chinese as the Sai (Chinese: 塞, Old Sinitic *sək).

Tehát a szakákat a kutatók többsége iráni nyelvű népnek tudja.
