taxable curiales: they became bondmen of the state or of their own municipality; they could not change their residence, and suffered innumerable annoyances. The curiales, thus goaded, often preferred even the hateful military service on the utmost frontiers of the empire: they voluntarily entered the legions, in order to be exempted from taxation and the grip of the imperial and municipal tax-gatherer. More of them, however, chose rather to seek patrons, and became bondmen to the rich, the slaveholders, and exempted persons, giving both themselves and their property to their protectors. Thus frequently the impoverished descendants of former _honoratiores_ became first bondmen and then slaves. During that long epoch of grinding oppression and taxation, the division and subdivision of the community into classes and grades originated. This classification was based on pursuits and occupations, and also according to the imposts levied on each class, from the magnate--as the rich social successors of the oligarchs were now called--down to the lowest laborer and chattel. Finally, the whole property in the Roman world--the country, the city, the lands, houses, and slaves--was centred in the hands of a few magnates, who owned incalculable numbers of colonists, bondmen, serfs, and chattels. The famous Roman legions were recruited from yeomen, plebeians, workmen and colonists; in one word, from the free population. When freemen diminished, foreigners and barbarians were hired and enrolled. Sylla's military murderers were in great part Spanish Celts; and after Sylla and Marius, foreigners entered more and more into the composition of the Roman armies. Caligula had a kind of body-guard composed of Germans; and soon all the nations conquered by Rome were represented, not only in the armies, but even under the imperial canopy. Then arose the intestine wars for imperial power carried on by pretenders, each _proclaimed_ by some province or legion. These wars resulted in slaughter, devastation, ruin and universal misery; and thus enlarged the number of slaves, and powerfully revived the slave traffic, which survived the downfall of heathenism and the Roman world.
