The increasing numbers of the plebs, the result of fresh wars, and the value of their services to the community, entitled them to possess, and emboldened them to claim, some political consideration. Accordingly, in the reign of Tarquinius Priscus, the fifth of the legendary kings, and in whose reputed Etruscan lineage historians fancy that they can discern a time when Etruscan influence, if not Etruscan arms, reigned paramount in Rome, a modification of the original constitution took place. A number of the richest plebeian families were drafted into the populus, to supply the blanks caused by the dying out of many of the ancient gentes of the Ramnes, Tities, and Luceres; and at the same time the number of senators was increased to 300, by the admission of the Luceres to the same rights as the other two tribes. Even this modification was insufficient; and in order to do justice to the claims of the plebs, Servius Tullius, the successor of Tarquinius, and who is gratefully celebrated in Roman history as ‘the King of the Commons,’ proposed and effected an entire renovation of the political system of the state. His first reform consisted in giving the plebs a regular internal organization for its own purposes, by dividing it into thirty tribes or parishes――four for the town, and twenty-six for the country――each provided with an officer or tribe convener called the Tribune, as well as with a detailed machinery of local government; and all permitted to assemble in a general meeting called the _Comitia Tributa_, to discuss matters purely affecting the plebs. But this was not all. To admit the plebs to a share in the general legislative power of the community, he instituted a third legislative body, called the _Comitia Centuriata_, in addition to the two――the senate and the comitia curiata――already existing. The comitia centuriata was an assembly of the whole free population of the Roman territory――patricians, plebeians, and clients――arranged, according to the amount of their taxable property, in five classes, which again were subdivided into 195 bodies, called _Centuries_, each century possessing a vote, but the centuries of the rich being much smaller than those of the poor, so as to secure a preponderance to wealth. The powers of the comitia centuriata were similar to those of the comitia curiata under the former system. They had the right to elect supreme magistrates, and to accept or reject a measure referred to them by the king and senate. The comitia curiata, however, still continued to be held; and a measure, even after it had passed the comitia centuriata, had still to be approved by the curies ere it could become a law. Notwithstanding this restriction, the constitution of Servius Tullius was a great concession to the popular spirit, as it virtually admitted every free individual within the Roman territory to a share in the government.
