It would be an important confirmation of my assertion as to the diverse character of our civilisation if we should find in its very cradle the causes and the elements of that diversity. And indeed, at the fall of the Roman empire, we do so find it. Three forms of society, each entirely different from the other, are visible at this time of chaos. The municipalities survived, the last remnant of the Imperial system. The Christian Church survived. And in the third place there were the Barbarians, who brought with them a military organisation, and a hardy individual independence, that were wholly new to the peoples who had dwelt under the shelter of the empire. The Barbarian epoch was the chaos of all the elements, the infancy of all the systems, a universal hubbub in which even conflict itself had no definite or permanent effects. Europe laboured to escape from this confusion; at some times, and in some places, it was temporarily checked--in particular by the great Charlemagne in his revival of the imperial power; but the confusion did not cease until its causes no longer acted. These causes were two--one material, one moral. The material cause was the irruption of fresh Barbarian hordes. The moral cause was the lack of any ideas in common among men as to the structure of society. The old imperial fabric had disappeared; Charlemagne's restoration of it depended wholly on his own personality, and did not survive him; men had no ideas of any new structure--their intellectual horizon was limited to their own affairs. By the beginning of the tenth century the Barbarian invasions ended, and as the populations settled down a new system appeared, based partly on the Barbarians' love of independence, partly on their plans of military gradation--the system of feudalism. A sound proof that in the tenth century the feudal system was necessary, and the only social state possible, lies in the universality of its establishment. Everywhere society was dismembered; everywhere there was formed a multitude of small, obscure, isolated societies, consisting of the chief, his family, his retainers, and the wretched serfs over whom he ruled without restraint, and who had no appeal against his whim. The power he exercised was the power of individual over individual, the domination of personal will and caprice; and this is perhaps the only kind of tyranny that man, to his eternal honour, is never willing to endure. Hence the prodigious and invincible hatred that the people have at all times entertained for feudal rule, for the memories of it, for its very name.
