The reasoning on this head has been abundantly exemplified by the experience of all federal constitutions with which we are acquainted, and of all others which have borne the least analogy to them.

Though the ancient feudal systems were not, strictly speaking, confederacies, yet they partook of the nature of that species of association. There was a common head, chieftain, or sovereign, whose authority extended over the whole nation; and a number of subordinate vassals, or feudatories, who had large portions of land allotted to them, and numerous trains of inferior vassals or retainers, who occupied and cultivated that land upon the tenure of fealty or obedience to the persons of whom they held it. Each principal vassal was a kind of sovereign, within his particular demesnes. The consequences of this situation were a continual opposition to authority of the sovereign, and frequent wars between the great barons or chief feudatories themselves. The power of the head of the nation was commonly too weak, either to preserve the public peace, or to protect the people against the oppressions of their immediate lords. This period of European affairs is emphatically styled by historians, the times of feudal anarchy.

When the sovereign happened to be a man of vigorous and warlike temper and of superior abilities, he would acquire a personal weight and influence, which answered, for the time, the purpose of a more regular authority. But in general, the power of the barons triumphed over that of the prince; and in many instances his dominion was entirely thrown off, and the great fiefs were erected into independent principalities or states. In those instances in which the monarch finally prevailed over his vassals, his success was chiefly owing to the tyranny of those vassals over their dependents. The barons, or nobles, equally the enemies of the sovereign and the oppressors of the common people, were dreaded and detested by both; till mutual danger and mutual interest effected a union between them fatal to the power of the aristocracy. Had the nobles, by a conduct of clemency and justice, preserved the fidelity and devotion of their retainers and followers, the contests between them and the prince must almost always have ended in their favor, and in the abridgment or subversion of the royal authority.

This is not an assertion founded merely in speculation or conjecture. Among other illustrations of its truth which might be cited, Scotland will furnish a cogent example. The spirit of clanship which was, at an early day, introduced into that kingdom, uniting the nobles and their dependants by ties equivalent to those of kindred, rendered the aristocracy a constant overmatch for the power of the monarch, till the incorporation with England subdued its fierce and ungovernable spirit, and reduced it within those rules of subordination which a more rational and more energetic system of civil polity had previously established in the latter kingdom.
