The limited authority of the prince in the feudal constitutions prevented the King of England from employing with advantage the force of so many states, which were subjected to his government; and these different members, disjoined in situation, and disagreeing in laws, language, and manners, were never thoroughly cemented into one monarchy. He soon became, both from his distant place of residence, and from the incompatibility of interests, a kind of foreigner to his French dominions; and his subjects on the continent considered their allegiance as more naturally due to their superior lord, who lived in their neighbourhood, and who was acknowledged to be the supreme head of their nation. He was always at hand to invade them; their immediate lord was often at too great a distance to protect them; and any disorder in any part of his dispersed dominions gave advantages against him. The other powerful vassals of the French crown were rather pleased to see the expulsion of the English, and were not affected with that jealousy, which would have arisen from the oppression of a co-vassal, who was of the same rank with themselves. By this means, the King of France found it more easy to conquer those numerous provinces from England, than to subdue a Duke of Normandy or Guienne, a Count of Anjou, Maine, or Poictou. And after reducing such extensive territories, which immediately incorporated with the body of the monarchy, he found greater facility in uniting to the crown the other great fiefs which still remained separate and independent.
