The history of the Middle Ages, though exhibiting constant resistance on the part of powerful subjects, frequent deposition of individual kings, and occasional changes of dynasty, contains few instances of any attempt to maintain a large political aggregate united without a king, either hereditary or elective. Even towards the close of the last century, at the period when the federal constitution of the United States of America was first formed, many reasoners regarded[9] as an impossibility the application of any other system than the monarchical to a territory of large size and population, so as to combine union of the whole with equal privileges and securities to each of the parts. And it might, perhaps, be a real impossibility among any rude people, with strong local peculiarities, difficult means of communication, and habits of representative government not yet acquired. Hence, throughout all the larger nations of mediæval and modern Europe, with few exceptions, the prevailing sentiment has been favorable to monarchy; but wherever any single city, or district, or cluster of villages, whether in the plains of Lombardy, or in the mountains of Switzerland, has acquired independence,—wherever any small fraction has severed itself from the aggregate,—the opposite sentiment has been found, and the natural tendency has been towards some modification of republican government;[10] out of which, indeed, as in Greece, a despot has often been engendered, but always through some unnatural mixture of force and fraud. The feudal system, evolved out of the disordered state of Europe between the eleventh and thirteenth centuries, always presumed a permanent suzerain, vested with large rights of a mixed personal and proprietary character over his vassals, though subject, also, to certain obligations towards them the immediate vassals of the king had subordinate vassals of their own, to whom they stood in the same relation: and in this hierarchy[11] of power, property, and territory blended together, the rights of the chief, whether king, duke, or baron, were always conceived as constituting a status apart, and neither conferred originally by the grant, nor revocable at the pleasure, of those over whom they were exercised. This view of the essential nature of political authority was a point in which the three great elements of modern European society,—the Teutonic, the Roman, and the Christian,—all concurred, though each in a different way and with different modifications; and the result was, a variety of attempts on the part of subjects to compromise with their chief, without any idea of substituting a delegated executive in his place. On particular points of these feudal monarchies there grew up, gradually, towns with a concentrated population, among whom was seen the remarkable combination of a republican feeling, demanding collective and responsible management in their own local affairs, with a necessity of union and subordination towards the
