It was under this Frederick that the Palatine Court exerted itself so vigorously to unite the Protestant states of Germany in joint measures against the House of Austria, and, if possible, bring about the formation of a general confederacy. Besides that this court had always been guided by the counsels of France, with whom hatred of the House of Austria was the ruling principle, a regard for his own safety urged him to secure in time the doubtful assistance of the Lutherans against a near and overwhelming enemy. Great difficulties, however, opposed this union, because the Lutherans' dislike of the Reformed was scarcely less than the common aversion of both to the Romanists. An attempt was first made to reconcile the two professions, in order to facilitate a political union; but all these attempts failed, and generally ended in both parties adhering the more strongly to their respective opinions. Nothing then remained but to increase the fear and the distrust of the Evangelicals, and in this way to impress upon them the necessity of this alliance. The power of the Roman Catholics and the magnitude of the danger were exaggerated, accidental incidents were ascribed to deliberate plans, innocent actions misrepresented by invidious constructions, and the whole conduct of the professors of the olden religion was interpreted as the result of a well-weighed and systematic plan, which, in all probability, they were very far from having concerted. The Diet of Ratisbon, to which the Protestants had looked forward with the hope of obtaining a renewal of the Religious Peace, had broken up without coming to a decision, and to the former grievances of the Protestant party was now added the late oppression of Donauwerth. With incredible speed, the union, so long attempted, was now brought to bear. A conference took place at Anhausen, in Franconia, at which were present the Elector Frederick IV., from the Palatinate, the Palsgrave of Neuburg, two Margraves of Brandenburg, the Margrave of Baden, and the Duke John Frederick of Wirtemburg, -- Lutherans as well as Calvinists, -- who for themselves and their heirs entered into a close confederacy under the title of the Evangelical Union. The purport of this union was, that the allied princes should, in all matters relating to religion and their civil rights, support each other with arms and counsel against every aggressor, and should all stand as one man; that in case any member of the alliance should be attacked, he should be assisted by the rest with an armed force; that, if necessary, the territories, towns, and castles of the allied states should be open to his troops; and that, whatever conquests were made, should be divided among all the confederates, in proportion to the contingent furnished by each.
