During the fourteenth and fifteenth centuries, however, another class rose into prominence and, perhaps because it was originally drawn to a great extent from the younger sons of the country gentry, found amalgamation with the gentry easy. The development of trade and the new openings for the employment of capital had brought about the rise of the English merchant class. Hitherto foreigners had financed the English crown, but during the first four years of the Hundred Years' War it became clear that English merchants were now rich and powerful enough to take their place; and the triumph of the native was complete when, in 1345, Edward III repudiated his debts to the Italian merchants and the Bardi and Peruzzi failed. Henceforth the English merchants were supreme; on the one hand their trading ventures enriched them; on the other they made vast sums out of farming the customs and the war subsidies in return for loans of ready money, and out of all sorts of government contracts. The successful campaigns of Crecy and Poitiers were entirely financed by these English capitalists. Not only trade but industry swelled the ranks of the _nouveaux riches_ and the clothiers of the fourteenth and fifteenth centuries grew rich and prospered. Evidences of the wealth and importance of this middle class are to be found on all sides. The taxation of movables, which from 1334 became an important and in time the main source of national revenue, indicates the discovery on the part of the government that the wealth of the nation no longer lay in land, but in trade. The frequent sumptuary acts, the luxury of daily life, bear witness to the wealth of the _nouveaux riches_; and so also do their philanthropic enterprises, the beautiful churches which they built, the bridges which they repaired, the gifts which they gave to religious and to civic corporations. And it was in the fourteenth century that there began that steady fusion between the country gentry and the rich burgesses, which was accomplished before the end of the middle ages and which resulted in the formation of a solid and powerful middle class. The political amalgamation of the two classes in the lower house of Parliament corresponded to a social amalgamation in the world outside. The country knights and squires saw in business a career for their younger sons; they saw in marriage with the daughters of the mercantile class a way to mend their fortunes; the city merchants, on the other hand, saw in such alliances a road to the attainment of that social prestige which went with land and blood, and were not loath to pay the price. "Merchants or new gentlemen I deem will proffer large," wrote Edmund Paston, concerning the marriage of one of his family. "Well I wot if ye depart to London ye shall have proffers large"[25].
