Who were called citizens in ancient Greece?

Everything is simple here: only the indigenous inhabitants of the polis were called citizens in Ancient Greece. But there was a small amendment, it was necessary to prove that the previous five generations also lived in the polis. The area was called a policy. It is worth knowing that Ancient Greece existed until the thirtieth year of our era. And it originated in the third millennium BC.
