The counts and other magistrates, whose power was merely official, were tempted, in imitation of the feudal lords, whom they resembled in so many particulars, to render their dignity perpetual and hereditary; and in the decline of the regal power, they found no difficulty in making good their pretentions.

After this manner the vast fabric of feudal subordination became quite solid and comprehensive; it formed every where an essential part of the political constitution; and the Norman and other barons, who followed the fortunes of William, were so accustomed to it, that they could scarcely form an idea of any other species of civil government.[*] The Saxons who conquered England, as they exterminated the ancient inhabitants, and thought themselves secured by the sea against new invaders, found it less requisite to maintain themselves in a military posture: the quantity of land which they annexed to offices seems to have been of small value; and for that reason continued the longer in its original situation, and was always possessed during pleasure by those who were intrusted with the command.

These conditions were too precarious to satisfy the Norman barons, who enjoyed more independent possessions and jurisdictions in their own country; and William was obliged, in the new distribution of land, to copy the tenures which were now become universal on the continent.

England of a sudden became a feudal kingdom,[**] and received all the advantages, and was exposed to all the inconveniences, incident to that species of civil polity.
According to the principles of the feudal law, the king wa the supreme lord of the landed property: all possessors, who enjoyed the fruits or revenue of any part of it, held those privileges, either mediately or immediately, of him; and their property was conceived to be, in some degree, conditional.[***] The land was still apprehended to be a species of benefice, which was the original conception of a feudal property; and the vassal owed, in return for it, stated services to his baron, as the baron himself did for his land to the crown.

The vassal was obliged to defend his baron in war; and the baron, at the head of his vassal, was bound to fight in defence of the king and kingdom.
