The Achaean War was an uprising by the Greek Achaean League, an alliance of Achaean and other Peloponnesian states in ancient Greece, against the Roman Republic around 146 BC, just after the Fourth Macedonian War. Rome defeated the League swiftly, and as a lesson, they destroyed the ancient city of Corinth. The war ended with Greece's independence taken away, and Greece became the Roman provinces of Achaea and Epirus.
