From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Samnium had recovered from the severe wars of the fifth century: according to the census of 529 it was in a position to furnish half as many men capable of arms as all the Latin towns, and it was probably at that time, next to the -ager Romanus-, the most flourishing region of the peninsula. But the Hannibalic war had desolated the land afresh, and the assignations of land in that quarter to the soldiers of Scipio's army, although considerable, probably did not cover the loss. Campania and Apulia, both hitherto well-peopled regions, were still worse treated in the same war by friend and foe. In Apulia, no doubt, assignations of land took place afterwards, but the colonies instituted there were not successful.
The beautiful plain of Campania remained more populous; but the territory of Capua and of the other communities broken up in the Hannibalic war became state-property, and the occupants of it were uniformly not proprietors, but petty temporary lessees. Lastly, in the wide Lucanian and Bruttian territories the population, which was already very thin before the Hannibalic war, was visited by the whole severity of the war itself and of the penal executions that followed in its train; nor was much done on the part of Rome to revive the agriculture there--with the exception perhaps of Valentia (Vibo, now Monteleone), none of the colonies established there attained real prosperity.
