In very many cases we are actually enabled to see how freedom and legal security gradually emerge from subjection. One of the great movements in the social life of the thirteenth and fourteenth centuries is the movement towards the commutation of services for money rents. In every survey we find a certain number of persons who now pay money, whereas they used to do work, and who have thus emancipated themselves from the most onerous form of subjection[369]. In the older documents it is commonly specified that the lord may revert to the old system, give up the rents, and enforce the services[370]. In later documents this provision disappears, having become obsolete, and there is only a mention of certain sums of money. The whole process, which has left such distinct traces in the authorities, is easily explained by England's economic condition at that time. Two important factors co-operated to give the country an exceptionally privileged position. England was the only country in Europe with a firmly constituted government. The Norman Conquest had powerfully worked in the sense of social feudalism, but it had arrested the disruptive tendencies of political feudalism. The opposition between the two races, the necessity for both to keep together, the complexity of political questions which arose from conquest and settlement on the one hand, from the intercourse with Normandy and France on the other,--all these agencies working together account for a remarkable intensity of action on the part of the centripetal forces of society, if I may use the expression: there was in England a constant tendency towards the concentration and organisation of political power in sharp contrast with the rest of Europe where the state had fallen a prey to local and private interests. One of the external results of such a condition was the growth of a royal power supported by the sympathy of the lower English-born classes, but arranging society by the help of Norman principles of fiscal administration. Not less momentous was the formation of an aristocracy which was compelled to act as a class instead of acting as a mere collection of individuals each striving for his own particular advantage; as a class it had to reckon with, and sometimes represent, the interests and requirements of other classes. In all these respects England was much ahead of Germany, where tribal divisions were more powerful than national unity, and the state had to form itself on feudal foundations in opposition to a cosmopolitan Imperial power; it was not less in advance of France, where the work of unification, egotistically undertaken by the king, had hardly begun to get the upper hand in its conflict with local dynasties; not less in advance of Italy, so well situated for economic progress, but politically wrecked by its unhappy connexion with Germany, the anti-national influence of the Papacy, and the one-sided development of municipal institutions. By reason of its
