Influence of the Extension of the Roman Dominion in Elevating the Farmer-Class
A more effectual relief than any which the government was willing or able to give was derived by the middle classes from the political successes of the Roman community and the gradual consolidation of the Roman sovereignty over Italy. The numerous and large colonies which it was necessary to found for the securing of that sovereignty, the greater part of which were sent forth in the fifth century, furnished a portion of the agricultural proletariate with farms of their own, while the efflux gave relief to such as remained at home.
The increase of the indirect and extraordinary sources of revenue, and the flourishing condition of the Roman finances in general, rendered it but seldom necessary to levy any contribution from the farmers in the form of a forced loan. While the earlier small holdings were probably lost beyond recovery, the rising average of Roman prosperity must have converted the former larger landholders into farmers, and in so far added new members to the middle class.
People of rank sought principally to secure the large newly-acquired districts for occupation; the mass of wealth which flowed to Rome through war and commerce must have reduced the rate of interest; the increase in the population of the capital benefited the farmer throughout Latium; a wise system of incorporation united a number of neighbouring and formerly subject communities with the Roman state, and thereby strengthened especially the middle class; finally, the glorious victories and their mighty results silenced faction.
If the distress of the farmers was by no means removed and still less were its sources stopped, it yet admits of no doubt that at the close of this period the Roman middle class was on the whole in a far less oppressed condition than in the first century after the expulsion of the kings.
