The notion of compacts with the devil was a familiar one, and that it should be resorted to for the purpose of acquiring an acquaintance with hidden lore and magical powers seemed quite natural. It will have already been seen from what we have said that the religious revolt was largely economical in its causes. The intense hatred, common alike to the smaller nobility, the burghers and the peasants, of the ecclesiastical hierarchy, was obviously due to its ever-increasing exactions. The sudden increase in the sale of indulgences, like the proverbial last straw, broke down the whole system; but any other incident might have served the purpose equally well. The prince-prelates were, in some instances, at the outset, not averse to the movement; they would not have been indisposed to have converted their territories into secular fiefs of the Empire. It was only after this hope had been abandoned that they definitely took sides with the Papal authority. The opening of the sixteenth century thus presents to us mediæval society, social, political and religious, "run to seed". The feudal organisation was outwardly intact; the peasant, free and bond, formed the foundation; above him came the knighthood or inferior nobility; parallel with them was the _Ehrbarkeit_ of the less important towns, holding from mediate lordship; above these towns came the free cities, which held immediately from the Empire, organised into three bodies, a governing Council in which the _Ehrbarkeit_ usually predominated, where they did not entirely compose it, a Common Council composed of the masters of the various guilds, and the General Council of the free citizens. Those journeymen, whose condition was fixed from their being outside the guild-organisations, usually had guilds of their own. Above the free cities in the social pyramid stood the Princes of the Empire, lay and ecclesiastic, with the Electoral College, or the seven Electoral Princes, forming their head. These constituted the feudal "estates" of the Empire. Then came the King of the Romans; and, as the apex of the whole, the Pope in one function and the Emperor in another crowned the edifice. The supremacy, not merely of the Pope, but of the complementary temporal head of the mediæval polity, the Emperor, was acknowledged in a shadowy way, even in countries such as France and England, which had no direct connection with the Empire. For, as the spiritual power was also temporal, so the temporal political power had, like everything else in the Middle Ages, a quasi-religious significance.
