These were disasters no less than the defeat on the Allia, and the Roman senate seems to have felt them as such and to have made use of the favourable turn, which the Italian relations assumed soon after the conclusion of the humiliating treaties with Carthage and Tarentum, with all energy to improve its depressed maritime position. The most important of the coast towns were furnished with Roman colonies: Pyrgi the seaport of Caere, the colonization of which probably falls within this period; along the west coast, Antium in 415,(11) Tarracina in 425,(12) the island of Pontia in 441,(13) so that, as Ardea and Circeii had previously received colonists, all the Latin seaports of consequence in the territory of the Rutuli and Volsci had now become Latin or burgess colonies; further, in the territory of the Aurunci, Minturnae and Sinuessa in 459;(14) in that of the Lucanians, Paestum and Cosa in 481;(15) and, on the coast of the Adriatic, Sena Gallica and Castrum Novum about 471,(16) and Ariminum in 486;(17) to which falls to be added the occupation of Brundisium, which took place immediately after the close of the Pyrrhic war. In the greater part of these places--the burgess or maritime colonies(18)--the young men were exempted from serving in the legions and destined solely for the watching of the coasts. The well judged preference given at the same time to the Greeks of Lower Italy over their Sabellian neighbours, particularly to the considerable communities of Neapolis, Rhegium, Locri, Thurii, and Heraclea, and their similar exemption under the like conditions from furnishing contingents to the land army, completed the network drawn by Rome around the coasts of Italy.
