What were the main Greek tribes called?

Somewhere within 1,000 BC. the tribes of the Achaeans pushed aside the Dorians, who at that time represented the Greek people. Even before that, the Cretan-Mycenaean civilization existed in the 13th century BC. She, in turn, appeared after the Minoan civilization, which lived on the island of Crete 2 -1.7 thousand years BC.

True, when Rome conquered the Greek city-states in the 2nd century BC, the Romans began to call the Greeks – Hellenes. Despite the fact that 2 thousand years have passed, the Greeks still continue to call themselves Hellenes.
