The Roman–Latin wars were a series of wars fought between ancient Rome (including both the Roman Kingdom and the Roman Republic) and the Latins, from the earliest stages of the history of Rome until the final subjugation of the Latins to Rome in the aftermath of the Latin War.
The Latins first went to war with Rome in the 7th century BC during the reign of the Roman king Ancus Marcius.
According to Livy the war was commenced by the Latins who anticipated Ancus would follow the pious pursuit of peace adopted by his grandfather, Numa Pompilius. The Latins initially made an incursion on Roman lands. When a Roman embassy sought restitution for the damage, the Latins gave a contemptuous reply. Ancus accordingly declared war on the Latins. The declaration is notable since, according to Livy, it was the first time that the Romans had declared war by means of the rites of the fetials.
Ancus Marcius marched from Rome with a newly levied army and took the Latin town of Politorium by storm. Its residents were removed to settle on the Aventine Hill in Rome as new citizens, following the Roman traditions from wars with the Sabines and Albans. When the other Latins subsequently occupied the empty town of Politorium, Ancus took the town again and demolished it. Further citizens were removed to Rome when Ancus conquered the Latin towns of Telleni and Ficana.
The war then focused on the Latin town of Medullia. The town had a strong garrison and was well fortified. Several engagements took place outside the town and the Romans were eventually victorious. Ancus returned to Rome with much loot. More Latins were brought to Rome as citizens and were settled at the foot of the Aventine near the Palatine Hill, by the temple of Murcia.
