Greece was eventually taken over in 30 b. c. by

Rome

Explanation:

The decline of Ancient Greece began as the Romans became more powerful in the Italian peninsula. Initially, Rome declared war on Macedonia (northern Greece) and defeated them at Cynoscephalae in 197 BC and at Pydna in 168 BC. The Greeks were defeated again at Corinth in 146 BC. The last vestiges of classical Greece were conquered when Rome took control of Egypt in 31 BC.
