This kind of property existed in Gaul before the invasion of the Franks. The conquest that resulted from this invasion contributed in various ways to augment their number. First, wherever a Barbarian possessed of some amount of power established himself, he did not take possession of all the lands, but he most probably exacted certain fees, or services equivalent to them, from almost all whose lands bordered on his own. This is certain from à priori considerations, and is proved as a fact by the example of the Lombards, who invariably contented themselves at first with rendering all the lands of the conquered country tributary to themselves. They demanded a third of the revenue, and afterwards took the property itself. This fact shows clearly the mode of procedure that was adopted by the Barbarians. Almost all the lands possessed by Roman or Gallic chiefs, who did not possess sufficient power to rank with the Barbarians, were obliged to submit to a tributary condition.

Secondly, conquest was not the work of a single day; it continued to be carried on after the establishment of the invaders. All the documents of the period indicate that the principal officers and large proprietors continually exerted themselves, either to usurp the possessions of their less powerful neighbours, or to impose upon them rentals or other charges. These usurpations are proved by the multitude of laws that were enacted to prevent it. In the unsettled state of society that then existed, the feeble were entirely placed at the disposal of the strong; public authority had become incompetent for their protection; many lands which were at first free, and belonged either to their ancient owners, or to Barbarians of slender resources, fell into a tributary state; many of the smaller proprietors purchased for themselves the protection of the strong, by voluntarily placing their lands in this condition. The most common method of rendering lands tributary, was to give them either to churches or to powerful proprietors, and then to receive them again, on the tenure of usufruct, to be enjoyed during life, on the payment of fixed fees. This kind of contract is to be met with again and again, during this period. The same causes which tended to destroy allods, or to convert them into benefices, acted with even more energy in augmenting the number of tributary lands.

Thirdly, many large proprietors, whether of allodial lands or of benefices, were unable themselves to cultivate the whole of their lands, and gave them up by small portions to simple cultivators, on the payment of certain fees and services. This alienation took place under a multitude of forms and a variety of circumstances; it certainly occasioned many lands to become tributary. The large number and endless variety of rentals and rights, known in a later time by the name of feudal, arose probably either from similar contracts, or from usurpations committed by the powerful proprietors. The constant recurrence in writers and laws of the period of the terms census and tributum; the multitude of arrangements which relate to them; the general course of events; lastly, the state in which most landed property was found when order began to reappear,—all these circumstances render it probable that at the end of the period we are considering, the greater number of lands had fallen into a tributary condition. Property and liberty were alike devoted to be plundered. Individuals were so isolated, and their forces so unequal, that nothing could prevent the results of such a position.

Waste Lands.

The large number of waste lands, attested by the facility with which any one who was willing to cultivate them might obtain them, bears witness in its turn also to the depopulation of the country, and the deplorable condition in which property existed. The concentration of landed property is a decisive proof of this state of things. When this kind of property is safe and prosperous, it tends to become divided, because every one desires to possess it. When, on the other hand, we see it accumulated more and more in the same hands, we may almost certainly conclude that it is in an unsound condition, that the feeble cannot sustain themselves upon it, and that the strong alone can defend it. Landed property, like moveable property, is only to be found where it can continue to exist in safety.

There is reason to believe that most tributary lands, even those which were not originally the property of the cultivators who laboured on them, became at length by a right of occupancy in reality their possessions, though burdened by rentals and exactions of service. This is the natural course of things: it is very difficult to remove a cultivator who has with his family for a long time tilled the same soil.

Different Kinds Of Landed Property.

Such were the vicissitudes of landed property, from the sixth to the eleventh century. I will now give a summary view of the general characteristics of this state of things, and endeavour to estimate their influence on the progress of general civilization, and more particularly of political institutions.
