A brief overview of the fall of the Greeks
The Greeks had founded a colony at Cumae in the C8th BC which established another at nearby Neapolis (New City, which is now Naples) but during the Macedonian domination of the Greek world under Alexander the Great, the Romans began to emerge as one of the stronger peoples of Italy.
Their second war with Macedonia (200-197 BC) led to a recognition of the rise of Rome throughout the Mediterranean. Philip V of Macedon made an alliance with Hannibal in 205 which produced Roman intervention in Greece and a treaty of co-existence, the Peace of Phoenice and after Greek defeat by Flaminius in 197 BC, Rome was the main power in the Aegean.
