History of Tamil Nadu
Ancient Tamil Nadu contained three monarchical states, headed by kings called Ventar and several tribal chieftaincies, headed by the chiefs called by the general denomination Vel or Velir. During the third century BCE, the Deccan was part of the Mauryan kingdom, and from the middle of the first century BCE to second century CE the same area was ruled by the Satavahana dynasty. The Tamil area had an independent existence outside the control of these northern empires.
