The township in Germany was of two kinds--first of all, there was the township that was "free of the Empire," that is, that held nominally from the Emperor himself (_Reichstadt_), and secondly, there was the township that was under the domination of an intermediate lord. The economic basis of the whole was still land; the status of a man or of a corporation was determined by the mode in which they held their land. "No land without a lord" was the principle of mediaeval polity; just as "money has no master" is the basis of the modern world with its self-made men. Every distinction of rank in the feudal system was still denoted for the most part by a special costume. It was a world of knights in armour, of ecclesiastics in vestments and stoles, of lawyers in robes, of princes in silk and velvet and cloth of gold, and of peasants in laced shoe, brown cloak, and cloth hat. But although the whole feudal organization was outwardly intact, the thinker who was watching the signs of the times would not have been long in arriving at the conclusion that feudalism was "played out," that the whole fabric of mediaeval civilization was becoming dry and withered, and had either already begun to disintegrate or was on the eve of doing so. Causes of change had within the past half-century been working underneath the surface of social life, and were rapidly undermining the whole structure. The growing use of firearms in war; the rapid multiplication of printed books; the spread of the new learning after the taking of Constantinople in 1453, and the subsequent diffusion of Greek teachers throughout Europe; the surely and steadily increasing communication with the new world, and the consequent increase of the precious metals; and, last but not least, Vasco da Gama's discovery of the new trade route from the East by way of the Cape--all these were indications of the fact that the death-knell of the old order of things had struck. Notwithstanding the apparent outward integrity of the system based on land tenures, land was ceasing to be the only form of productive wealth. Hence it was losing the exclusive importance attaching to it in the earlier period of the Middle Ages. The first form of modern capitalism had already arisen. Large aggregations of capital in the hands of trading companies were becoming common. The Roman law was establishing itself in the place of the old customary tribal law which had hitherto prevailed in the manorial courts, serving in some sort as a bulwark against the caprice of the territorial lord; and this change facilitated the development of the bourgeois principle of private, as opposed to communal, property. In intellectual matters, though theology still maintained its supremacy as the chief subject of human interest, other interests were rapidly growing up alongside of it, the most prominent being the study of classical literature.
