Achaia was a Roman province in Greece that included the Peloponnese, Attica, Boeotia, the Cyclades, and parts of Phthiotis, Aetolia, and Procis. The Romans annexed it in 146 BC following the sack of Corinth.
Achaia was originally part of the Roman province of Macedonia, but the Roman emperor Caesar Augustus made it a separate province.
