Saka

The Sakas were a population of Iranic nomadic tribesmen lived in the plains of Eurasia from Eastern Europe to China, from the Old Persian Period to the Middle Persian Period. Then Turkic language speakers took their place.
The ancient Greeks called the Sakas the Scythians.
Sakas came across the river Indus and overan Sind and Saurashtra (near Gujrat) .They finally settled down in Kathiawar and malwa. They were often in war with the Satavahanas. Rudradaman, one of their best known king was the one who stopped the expansion of Sata ahana power to the north of river Narmada. The Sakas themselves could not expand to the north as they would have liked to, because Kushanas held them back.
