=15.= Tullus Hostil´ius, the third king of Rome, is the first of whose deeds we have any trustworthy account. He conquered Alba Longa, and transferred its citizens to the Cæ´lian Hill in Rome. This new city then became the protectress of the Latin League, with the right of presiding at the annual festival, though it was never, like Alba, a member of the League, but a distinct power in alliance with it. The federal army was commanded alternately by a Roman and a Latin general; and the lands acquired in the wars of the League were equally divided between the two contracting parties, thus giving to Rome, it is evident, a far greater share than to any other city. =16.= The citizens of consolidated Rome now constituted three tribes: the _Ram´nes_, or original Romans, on the Palatine; the _Tit´ies_, or Sabines, on the Capitoline and Quirinal; and the _Lu´ceres_, on the Cælian. Each tribe consisted of ten _cu´riæ_, or wards, and each _curia_ of ten _houses_, or clans (_gentes_). The patrician, or noble, houses, which alone enjoyed the rights of citizenship, thus numbered three hundred. The heads of all the houses constituted the Senate, while the _Comit´ia Curia´ta_, or public assembly, included all citizens of full age. Rome, at this period, contained only two classes beside the Patricians. These were the _clients_ and _slaves_. The former were the poorer people who belonged to no _gens_, and therefore, though free, had no civil rights. They were permitted to choose a patron in the person of some noble, who was bound to protect their interests, if need were, in courts of law. The client, on the other hand, followed his patron to war as a vassal; contributed to his ransom, or that of his children, if taken prisoners; and paid part of the costs of any lawsuit in which the patron might be engaged, or of his expenses in discharging honorable offices in the state. The relation on either side descended from father to son. It was esteemed a glory to a noble family to have a numerous clientage, and to increase that which it had inherited from its ancestors. The clients bore the clan-name[63] of their patron. Slaves were not numerous in the days of the kings. During the Republic, multitudes of captives were brought into the market by foreign wars; and at the close of that period, at least half the inhabitants of Roman territory were bondsmen.
