The greater feudal States, Electoral and Ducal Saxony, Brandenburg, Bavaria, the Palatinate, Hesse, and many others, had meetings of their own Estates,—Councils of subservient nobles and lawyers,—their own Supreme Courts of Justice, from which there was no appeal, their own fiscal system, their own finance and coinage, and largely controlled their clergy and their relations to powers outside Germany. Their princes, hampered as they were by the great Churchmen, thwarted continually by the town republics, defied by the free nobles, were nevertheless actual kings, and profited by the centralising tendencies of the times. They alone in Germany represented settled central government, and attracted to themselves the smaller units lying outside and around them. Yet with all these divisions, having their roots deep down in the past, there was pervading all classes of society, from princes to peasants, the sentiment of a united Germany, and no lack of schemes to convert the feeling into fact. The earliest practical attempts began with the union of German Churchmen at Constance and the scheme for a National Church of Germany; and the dream of ecclesiastical unity brought in its train the aspiration after political oneness. The practical means proposed to create a German national unity over lands which stretched from the Straits of Dover to the Vistula, and from the Baltic to the Adriatic, were the proclamation of a universal Land’s Peace, forbidding all internecine war between Germans; the establishment of a Supreme Court of Justice to decide quarrels within the Empire; a common coinage, and a common Customs Union. To bind all more firmly together there was needed a Common Council or governing body, which, under the Emperor, should determine the Home and Foreign Policy of the Empire. The only authorities which could create a governmental unity of this kind were the Emperor on the one hand and the great princes on the other, and the two needed to be one in mutual confidence and in intention. But that is what never happened, and all through the reign of Maximilian and in the early years of Charles we find two different conceptions of what the central government ought to be—the one oligarchic and the other autocratic. The princes were resolved to keep their independence, and their plans for unity always implied a governing oligarchy with serious restraint placed on the power of the Emperor; while the Emperors, who would never submit to be controlled by an oligarchy of German princes, and who found that they could not carry out their schemes for an autocratic unity, were at least able to wreck any other.
