v1.c39.s3.16

The Nanda empire (354-324 B.C.) based in Pataliputra did spread into the Peninsular India in the south, but a pan-Indian situation developed only during the rule of the Maurya dynasty (322-200 B.C.). To ensure protection against enemies and also hegemony and prosperity in their vast empire, the Mauryas introduced state-controlled economy. This promoted rapid growth of mining, metallurgy, semi-precious gem and bead industries (such as at Sonkh), weaving industries (at Mathura, Varanasi, Banga, Kalinga etc.). Weights and measures were standardised.
