Tarquin had a favorite, Servius Tullius, said to have been the son of a female slave taken at the capture of the Latin town Corniculum. His infancy was marked by prodigies which foreshadowed his future greatness. On one occasion a flame played around his head, as he was asleep, without harming him. Tanaquil foresaw the greatness of the boy, and from this time he was brought up as the king's child. Tarquin afterward gave him his daughter in marriage, and left the government in his hands. But the sons of Ancus Marcius, fearing lest Tarquin should transmit the crown to his son-in-law, hired two countrymen to assassinate the king. These men, feigning to have a quarrel, came before the king to have their dispute decided, and while he was listening to the complaint of one, the other gave him a deadly wound with his axe. But the sons of Ancus did not reap the fruit of their crime; for Tanaquil, pretending that the king's wound was not mortal, told them that he would soon return, and that he had, meantime, appointed Servius to act in his stead. Servius forthwith proceeded to discharge the duties of king, greatly to the satisfaction of the people; and when the death of Tarquin could no longer be concealed, he was already in firm possession of the regal power. Tarquin had reigned thirty-eight years. 6. SERVIUS TULLIUS, B.C. 578-534.--Servius thus succeeded to the throne without being elected by the Senate and the Assembly of the Curiae. The reign of this king is almost as barren of military exploits as that of Numa. His great deeds were those of peace; and he was regarded by posterity as the author of the later Roman constitution, just as Romulus was of the earlier. Three important acts are assigned to Servius by universal tradition. Of these the greatest was: I. The reform of the Roman Constitution. In this reform his two main objects were to give the Plebeians political rights, and to assign to property that influence in the state which had previously belonged exclusively to birth. To carry his purpose into effect he made a twofold division of the Roman people, one territorial and the other according to property. _a._ It must be recollected that the only existing political organization was that of the Patricians into 3 tribes, 30 curiae, and 300 gentes; but Servius now divided the whole Roman territory into _Thirty Tribes_, and, as this division was simply local, these tribes contained Plebeians as well as Patricians. But, though the institution of the Thirty Tribes gave the Plebeians a political organization, it conferred upon them no political power, nor any right to take part in the elections, or in the management of public affairs. At a later time the tribes assembled in the forum for the transaction of business, and were hence called _Comitia Tributa_. The Patricians were then excluded from this assembly, which was summoned by the Tribunes of the Plebs, and was entirely Plebeian.
