The Domain Question under the Restoration
All those measures which were devised by Gaius Gracchus for the promotion of the public welfare--the best but, as may readily be conceived, also the most unpopular part of his legislation--were allowed by the aristocracy to drop. Nothing was so speedily and so successfully assailed as the noblest of his projects, the scheme of introducing a legal equality first between the Roman burgesses and Italy, and thereafter between Italy and the provinces, and--inasmuch as the distinction between the merely ruling and consuming and the merely serving and working members of the state was thus done away-- at the same time solving the social question by the most comprehensive and systematic emigration known in history.
With all the determination and all the peevish obstinacy of dotage the restored oligarchy obtruded the principle of deceased generations--that Italy must remain the ruling land and Rome the ruling city in Italy--afresh on the present. Even in the lifetime of Gracchus the claims of the Italian allies had been decidedly rejected, and the great idea of transmarine colonization had been subjected to a very serious attack, which became the immediate cause of Gracchus' fall. After his death the scheme of restoring Carthage was set aside with little difficulty by the government party, although the individual allotments already distributed there were left to the recipients.
