The cities, also, whose extensive privileges had constituted one of the most striking features of the political system of mediæval Europe, had been shorn of their exorbitant claims founded upon royal charters or prescriptive usage. The kings of France, in particular, had favored the growth of the municipalities, in order to secure their assistance in the reduction of refractory vassals. Flourishing trading communities had sprung up on the coasts of the Mediterranean Sea and of the ocean, and on the banks of the navigable rivers emptying into them. These corporations had secured a degree of independence proportioned, for the most part, to the weakness of their neighbors. The policy of the crown had been, while generously conferring privileges of great importance upon the cities lying within the royal domain, to make still more lavish concessions in favor of the municipalities upon or contiguous to the lands of the great feudatories.[13] [Sidenote: The capital.] No sooner, however, did the humiliation of the landed nobility render it superfluous to conciliate the good-will of the proud and opulent citizens, than the readiest means were sought for reducing them to the level of ordinary subjects. Paris especially, once almost a republic, had of late learned submission and docility.[14] By the change, however, the capital had lost neither wealth nor inhabitants, being described as very rich and populous, covering a vast area, and wholly given up to trade.[15] In the absence of an accurate census, the number of its inhabitants was variously stated at from 300,000 souls to nearly thrice as many; but all accounts agreed in placing Paris among the foremost cities of the civilized world.[16] [Sidenote: Military resources.]
