Ferdinand had it now in his power, for the second time, to secure the tranquillity of Germany; and it depended solely on his will whether the treaty with Denmark should or should not be the basis of a general peace. From every quarter arose the cry of the unfortunate, petitioning for an end of their sufferings; the cruelties of his soldiers, and the rapacity of his generals, had exceeded all bounds. Germany, laid waste by the desolating bands of Mansfeld and the Duke of Brunswick, and by the still more terrible hordes of Tilly and Wallenstein, lay exhausted, bleeding, wasted, and sighing for repose. An anxious desire for peace was felt by all conditions, and by the Emperor himself; involved as he was in a war with France in Upper Italy, exhausted by his past warfare in Germany, and apprehensive of the day of reckoning which was approaching. But, unfortunately, the conditions on which alone the two religious parties were willing respectively to sheath the sword, were irreconcileable. The Roman Catholics wished to terminate the war to their own advantage; the Protestants advanced equal pretensions. The Emperor, instead of uniting both parties by a prudent moderation, sided with one; and thus Germany was again plunged in the horrors of a bloody war. From the very close of the Bohemian troubles, Ferdinand had carried on a counter reformation in his hereditary dominions, in which, however, from regard to some of the Protestant Estates, he proceeded, at first, with moderation. But the victories of his generals in Lower Germany encouraged him to throw off all reserve. Accordingly he had it intimated to all the Protestants in these dominions, that they must either abandon their religion, or their native country, -- a bitter and dreadful alternative, which excited the most violent commotions among his Austrian subjects. In the Palatinate, immediately after the expulsion of Frederick, the Protestant religion had been suppressed, and its professors expelled from the University of Heidelberg.
