What is the name of the rulers who were people of Central Asian origin and established kingdoms in the north-western and western parts of the subcontinent?

Shakas

Shakas, a people of Central Asian origin who established kingdoms in the north-western and western parts of the subcontinent, derived revenues from long-distance trade. Their social origins were often obscure, but, as we will see in the case of the Satavahanas, once they acquired power they attempted to claim social status in a variety of ways.
