These latter were the plebeians. This class was made up of the descendants of the ancient people who of old had inhabited the country, ordinary foreigners who were attracted to the city, and the children of captives who had been given their liberty. At first, the plebeians enjoyed no rights whatever. They lived, it is true, under the shelter of the walls of the city, but on the outside. They possessed no right of suffrage, and were not allowed to interfere in any public affair. But they were free. They held property and engaged in handicrafts and in commerce. It soon came to pass that the increase of their number and their importance rendered their repression by the nobles more and more difficult. Under King Servius the plebeians became citizens; and, as is the case in every land, the internal history of Rome contains nothing more interesting than the indomitable and successful struggle of this lower class to wrest ever larger privileges from the tenacious rulers. It was not, however, until B.C. 444 that equality of rights had made sufficient progress for matrimonial alliances to be countenanced between patricians and plebeians. By the commencement of the Christian era all practical distinction between these two classes had vanished. In addition to the two principal orders, there was that of the clients. These were in reality vassals, who preferred dependence on the great and wealthy to living independently in a precarious liberty. They were called by the names of their patrons and were numbered in the latter's tribe. By enactments of law, the patron was made responsible for the support and protection of his clients. In return, the patrician could depend upon his clients to fight his battles, support his cause, and prove themselves loyal retainers of his house in both good fortune and evil. The subservience of these clients, and the conscienceless zeal with which they furthered the designs, even the most wicked, of their masters, are well illustrated in the part which Marcus Claudius played in the persecution of Virginia by the decemvir Appius. Another dependent class was that of the slaves. At first the number of these was comparatively small; but as the conquering arms of Rome spread over the world her avaricious sway, the captives dragged in barbarous triumph to the city grew out of all proportion to the population. They enjoyed fewer rights and suffered under a regime more inhuman than in any other slaveholding nation in history.
