Only the original Roman citizen of the three old tribes, that is to say, the patrician, could, according to the earliest law, be admitted to the _possessio_. He got from the prætor as much as he thought he could cultivate, no limits whatever being fixed; and for this he had nothing to pay, but only to invest his capital in making the land productive. The _Plebes_ now grew up at the side of this order. These were the real strength of Rome: they furnished the whole of the infantry; their blood was shed in the wars; and they achieved the conquests. It was therefore undoubtedly also the right of the _Plebes_ to have their share in these conquests: the _Populus_, however, continued to look upon these as their own property. Servius Tullius had already ordered that no more unlimited grants should be made, but that a part of the conquered land should remain with the state, and that the rest should be divided among the _Plebes_ as their freeholds. According to the rules of the augural system, squares were made, and then lots were numbered, and tickets issued to all those who were to have a share: each of these tickets represented a square (_centuria_). This is called _assignatio_. Such is the law of Servius Tullius, which is inseparably connected with the constitution of the _Plebes_. From Sallust’s expressions, we are to suppose that after the expulsion of the kings the Servian institutions were restored. Yet they were again done away by the patricians. Only the _ager regius_ was as yet divided; afterwards every thing remained with the patricians, who likewise dispensed themselves from paying the tithes. The tribunes were anything but mutinous; they only wished as the natural advocates of their order to make good its right. Perhaps the plebeians felt particularly aggrieved by the Etruscan war, as they had to sustain the deficiency of the lost third.
