When did the Greece civilization begin and end?

The beginnings of Ancient Greece are typically located in the 12th century BC (or, BCE), although precise dates are impossible to give. The Greek Classical Age occurred between 500 and 350 BC (or, BCE), followed by the Hellenistic Period until approximately 150 BC (or, BCE) and then the period of Roman domination. The formal end of Ancient Greece is often tied to the closing of the Athenian Academy in 529 AD (or, CE).
