[As this chapter is principally designed for advanced students, it has not been thought necessary to add questions for examination.] The contests respecting agrarian laws occupy so large a space in Roman history, and are so liable to be misunderstood, that it is necessary to explain their origin at some length. According to an almost universal custom, the right of conquest was supposed to involve the property of the land. Thus the Normans who assisted William I. were supposed to have obtained a right to the possessions of the Saxons; and in a later age, the Irish princes, whose estates were not confirmed by a direct grant from the English crown, were exposed to forfeiture when legally summoned to prove their titles. The extensive acquisitions made by the Romans, were either formed into extensive national domains, or divided into small lots among the poorer classes. The usufruct of the domains was monopolized by the patricians who rented them from the state; the smaller lots were assigned to the plebeians, subject to a tax called tribute, but not to rent. An agrarian law was a proposal to make an assignment of portions of the public lands to the people, and to limit the quantity of national land that could be farmed by any particular patrician.[1] Such a law may have been frequently impolitic, because it may have disturbed ancient possessions, but it could never have been unjust; for the property of the land was absolutely fixed in the state. The lands held by the patricians, being divided into extensive tracts, were principally used for pasturage; the small lots assigned to the plebeians were, of necessity, devoted to agriculture. Hence arose the first great cause of hostility between the two orders; the patricians were naturally eager to extend their possessions in the public domains, which enabled them to provide for their numerous clients, and in remote districts they frequently wrested the estates from the free proprietors in their neighbourhood; the plebeians, on the other hand, deemed that they had the best right to the land purchased by their blood, and saw with just indignation, the fruits of victory monopolized by a single order in the state. The tribute paid by the plebeians increased this hardship, for it was a land-tax levied on estates, and consequently fell most heavily on the smaller proprietors; indeed, in many cases, the possessors of the national domains paid nothing. From all this it is evident that an agrarian law only removed tenants who held from the state at will, and did not in any case interfere with the sacred right of property; but it is also plain that such a change must have been frequently inconvenient to the individual in possession. It also appears, that had not agrarian laws been introduced, the great body of the plebeians would have become the clients of the patricians, and the form of government would have been a complete oligarchy.
