The Battle of Corinth was a battle fought between the Roman Republic and the Greek city-state of Corinth and its allies in the Achaean League in 146 BC, which resulted in the complete and total destruction of Corinth. This battle marked the beginning of the period of Roman domination in Greek history.
In 146 BC, the Romans finally defeated and destroyed their main rival in the Mediterranean, Carthage, and spent the following months in provoking the Greeks, aiming to a final battle that would also strengthen their hold in this area. Cassius Dio reported that it was the Achaeans (Greeks) who began the quarrel. In the winter of that year the Achaean League rebelled against Roman predominance in Greece. Marching from Macedonia, the Romans defeated the first Achaean army under Critolaos of Megalopolis at the Battle of Scarpheia, and advanced unhindered onto Corinth.
The Roman consul Mummius, with 23,000 infantry and 3,500 cavalry (probably two legions plus Italian allies) with Cretans and Pergamese, advanced into the Peloponnese against the revolutionary Achaean government. The Achaean general Diaeus camped at Corinth with 14,000 infantry and 600 cavalry (plus possibly some survivors of another army that had been defeated earlier). The Achaeans made a successful night attack on the camp of the Roman advance guard, inflicting heavy casualties.
Encouraged by this success they offered battle the next day but their cavalry, heavily outnumbered, did not wait to receive the Roman cavalry charge and instead rapidly dispersed. The Achaean infantry, however, held the legions until a picked force of 1,000 Roman infantry charged their flank and broke them and the Achaeans retreated with order in the city walls. Some Achaeans took refuge in Corinth but no defense was organized because Diaeus fled to Arcadia.
Corinth was utterly destroyed in this year by the victorious Roman army and all of her treasures and art plundered. The entire adult male population was put to the sword and the female population and children sold into slavery. The annihilation of Corinth, the same fate met by Carthage the same year, marked a severe departure from previous Roman policy in Greece.
While there is archaeological evidence of some minimal habitation in the years afterwards, Julius Caesar refounded the city as Colonia Laus Iulia Corinthiensis in 44 BC, shortly before his assassination.
