"The rise of the craft gilds is, roughly speaking, a century later [than the rise of the merchant gilds]; isolated examples occur early in the twelfth century, they become more numerous as the century advances, and in the thirteenth century they appear in all branches of manufacture and in every industrial centre. Craft gilds were associations of all the artisans engaged in a particular industry in a particular town, for certain common purposes. … Their appearance marks the second stage in the history of industry, the transition from the family system to the artisan (or gild) system. In the former there was no class of artisans properly so called; no class, that is to say, of men whose time was entirely or chiefly devoted to a particular manufacture; and this because all the needs of a family or other domestic group, whether of monastery or manor-house, were satisfied by the labours of the members of the group itself. The latter, on the contrary, is marked by the presence of a body of men each of whom was occupied more or less completely in one particular manufacture. The very growth from the one to the other system, therefore, is an example of 'division of labour,' or, to use a better phrase, of 'division of employments.' … When the place of the young manufactures of the twelfth century in the development of mediæval society is thus conceived, the discussion as to a possible Roman 'origin' of the gilds loses much of its interest. No doubt modern historians have exaggerated the breach in continuity between the Roman and the barbarian world; no doubt the artisans in the later Roman Empire had an organization somewhat like that of the later gilds. Moreover, it is possible that in one or two places in Gaul certain artisan corporations may have had a continuous existence from the fifth to the twelfth century. It is even possible that Roman regulations may have served as models for the organization of servile artisans on the lands of monasteries and great nobles,—from which, on the continent, some of the later craft gilds doubtless sprang. But when we see that the growth of an artisan class, as distinguished from isolated artisans here and there, was impossible till the twelfth century, because society had not yet reached the stage in which it was profitable or safe for a considerable number of men to confine themselves to any occupation except agriculture; and that the ideas which governed the craft gilds were not peculiar to themselves but common to the whole society of the time; then the elements of organization which may conceivably have been derived from or suggested by the Roman artisan corporations become of quite secondary importance. There is, as we have said, little doubt that some of the craft gilds of France and Germany were originally organizations of artisan serfs on the manors of great lay or
