consolidated his power quite as much by his private as by his public measures. To guard against the children of Tarquin treating him as those of Ancus had treated Tarquin, he married his two daughters to the scions of the royal house, Lucius
and Arruns Tarquin.
Human counsels could not arrest the inevitable course of destiny, nor could Servius prevent the jealousy aroused by his ascending the throne from making his family the scene of disloyalty and hatred.
The truce with the Veientines had now expired, and the resumption of war with them and other Etruscan cities came most opportunely to help in maintaining tranquillity at home.
In this war the courage and good fortune of Tullius were conspicuous, and he returned to Rome
, after defeating an immense force of the enemy, feeling quite secure on the throne, and assured of the goodwill of both patricians and commons.
Then he set himself to by far the greatest of all works in times of peace. Just as Numa
had been the author of religious laws and institutions, so posterity extols Servius as the founder of those divisions and classes in the State by which a clear distinction is drawn between the various grades of dignity and fortune.
He instituted the census, a most beneficial institution in what was to be a great empire, in order that by its means the various duties of peace and war might be assigned, not as heretofore, indiscriminately, but in proportion to the amount of property each man possessed. From it he drew up the classes and centuries and the following distribution of them, adapted for either peace or war.
