But it is not solely the municipal authority which attacks the speculations born of the capitalistic spirit. The Church steps forward, and under the name of usury forbids indiscriminately the lending of money at interest, sales on credit, monopolies, and in general all profits exceeding the _justum pretium_. No doubt these prohibitions themselves attest the existence of the abuses which they endeavor to oppose, and their frequency proves that they did not always succeed. It is none the less true that they were very burdensome and that the pursuit of business on a large scale found itself much embarrassed by them.
The increasing specialization of commerce embarrassed it much more. At the beginning the merchants had devoted themselves to the most various operations at once. Wandering from market to market, they bought and sold without feeling in need of centring their activity on this or that kind of products or commodities, but from about 1250 this is no longer the case. The progress of economic evolution has resulted in localizing certain industries and in restraining certain branches of commerce to the groups of merchants best suited to their promotion. Thus, for example, in the course of the thirteenth century the trade in fine cloth became a monopoly of the towns of Flanders, and banking a monopoly of certain merchant companies of Lombardy, Provence, or Tuscany. Thenceforward commercial life ceases to overflow at random, so to speak. It has a less arbitrary, a more deliberate, and consequently a more embarrassed quality.
These limitations resting upon commerce have resulted in turning away from it the patricians, who moreover have become, as has been said above, a class of landed proprietors. The place which they left vacant is filled by new men, among whom, as among their predecessors, intelligence is the essential instrument of fortune. The intellectual faculties which the first developed in wandering commerce are used by these later men to overcome the obstacles raised in their pathway by municipal regulations of commerce and ecclesiastical regulations in respect to money affairs.[22] Many of them find a rich source of profit by devoting themselves to brokerage. Others in the industrial cities exploit shamelessly and in defiance of the statutes the artisans whom they employ. At Douai, for example, Jehan Boinebroke (1280-1310) succeeds in reducing to serfdom a number of workers (and characteristically, they are chiefly women) by advancing wool or money which they are unable to repay, and which therefore place them at his mercy.[23] The richest or the boldest profit by the constantly increasing need of money on the part of territorial princes and kings, to become their bankers. It will be remembered that it was Lombard capitalists who furnished Edward III. with money to prepare his campaigns against France,[24] and, quite recently, the history of Guillaume Servat of Cahors (1280-1320) has shown us a man who, setting out with nothing, like Godric in the eleventh century, accumulates in a few years a considerable fortune, supplies the King of England with a dowry for one of his daughters, lends money to the King of Norway, farms the wool duties at London, and, unscrupulous as he is shrewd, does not hesitate to engage in shady speculations upon the coinage.[25] And how many other financiers do we not know whose career is wholly similar: Thomas Fin at the court of the counts of Flanders,[26] the Berniers at that of the counts of Hainaut, the Tote Guis, the Vane Guis, at that of the kings of France, not to name the numberless Italians entrusted by the popes with the various operations of pontifical finance, those _mercatores Romanam curiam sequentes_ among whom are found the ancestors of the great Medici of the fifteenth century.[27]
