As despotic monarchs claiming the world for their realm, the Teutonic Emperors strove from the first against three principles, over all of which their forerunners of the elder Rome had triumphed,--those of Nationality, Aristocracy, and Popular Freedom. Their early struggles were against the first of these, and ended with its victory in the emancipation, one after another, of England, France, Poland, Hungary, Denmark, Burgundy, and Italy. The second, in the form of feudalism, menaced even when seeming to embrace and obey them, and succeeded, after the Great Interregnum, in destroying their effective strength in Germany. Aggression and inheritance turned the numerous independent principalities thus formed out of the greater fiefs, into a few military monarchies, resting neither on a rude loyalty, like feudal kingdoms, nor on religious duty and tradition, like the Empire, but on physical force, more or less disguised by legal forms. That the hostility to the Empire of the third was accidental rather than necessary is seen by this, that the very same monarchs who strove to crush the Lombard and Tuscan cities favoured the growth of the free towns of Germany. Asserting the rights of the individual in the sphere of religion, the Reformation weakened the Empire by denying the necessity of external unity in matters spiritual: the extension of the same principle to the secular world, whose fulness is still withheld from the Germans, would have struck at the doctrine of imperial absolutism had it not found a nearer and deadlier foe in the actual tyranny of the princes. It is more than a coincidence, that as the proclamation of the liberty of thought had shaken it, so that of the liberty of action made by the revolutionary movement, whose beginning the world saw and understood not in 1789, whose end we see not yet, should have indirectly become the cause which overthrew the Empire.
