These facilities for emancipation operated principally in favor of the urban chattels, or those of the household proper, and also rural overseers, but were rarely applied to the rural slaves; consequently, during the most brilliant period of the existence of the empire, the cities were filled with enfranchised slaves of various kinds and various nations. The country, too, was altogether abandoned by the slaveholders, who lived and rioted in the imperial city. Most of these emancipated slaves, as also, indeed, many of the free-born citizens, finally lost their liberty by the operation of those causes which, notwithstanding emancipations and state colonizations, continually increased the _latifundia_ or large estates, and transformed into bondmen the freeholders as well as those who rented land from the state or from private individuals. The civil administration of the Roman empire, heathen and Christian, down to its last agonies in Constantinople, may be very briefly summed up: it was _fiscality_. Every administrative measure aimed at replenishing the imperial exchequer. The imperial treasury was bottomless, and its owners cold, rapacious, cruel and insatiable. All the colonizations of free laborers had for their single aim but to increase the income of the state; and tributes and taxations of every conceivable kind were imposed, first upon the provinces, and in course of time, on Italy itself. These, of course, were principally supplied by the laboring classes in the cities and on the lands. The rapacity of the state was heightened also by the individual greed of the magistrates, from the prefects down to the meanest military or political official or tax-gatherer; indeed, locusts more destructive than the Roman officials never devoured the fruits of toil or the accumulations of industry. These fiscal measures and lawless extortions, fostered chattelhood almost as much as wars and conquests had formerly done.
