Vemaka

What is attested

A limited number of copper coins carry a Brahmi legend naming the Vemakas or Vaimakyas, without a royal name, in the corporate form used by the Yaudheyas, Mālavas and Ārjunāyanas. They are dated on stylistic and metrological grounds to roughly the second or first century BCE, and their find spots place the people in the eastern Punjab.

That is the whole of the evidence. There is no inscription, no literary notice that can be securely matched, no capital and no event. The Vemakas are recorded here because a coinage issued in a people's own name is proof that the people existed and governed themselves, and because the ancient Punjab contained many such polities of which only this much survives.
