between him and Zwingli, and persuaded the Lutheran Princes to admit no one to their alliance who would not subscribe to every single dogma in this formulary. As a natural result Strassburg and Ulm refused to sign the articles at Schwabach, and in this refusal they were joined by the other south German cities at a further conference held at Schmal-kalden in December. Luther even managed to shake the defensive understanding between Hesse and Saxony by persuading the Elector of the unlawfulness of any resistance to the Emperor. The Reformer was fortified in this attitude by a child-like faith-which Ferdinand was sagacious enough to encourage-in Charles' pacific designs, although the Emperor had denounced the Protest from Spain, was pledged by his treaty with the Pope to the extirpation of heresy, and arrested the Protestant envoys who appeared before him in Italy. So the far-reaching designs of Philip of Hesse and Zwingli for the defence of the Reformation were brought to naught at the moment when the horizon was clouding in every quarter.
In May, 1530, having in conjunction with Clement VII regulated the affairs of Italy and discussed schemes for regulating those of the world, Charles V crossed the Alps on his second visit to his German dominions. The auspices in 1530 were very different from those of 1521, Then he had left Spain in open rebellion, he was threatened with war by the most powerful State in Europe, and the attitude of the Papacy was still doubtful. Now Spain was reduced to obedience and the Pope to impotence; France had suffered the greatest defeat of the century; Italy lay at his feet; and Ferdinand had added two kingdoms to the family estate. Over every obstacle Charles seemed to have triumphed. But in Germany the universal agitation against Rome had resolved itself into two organised parties which threatened to plunge the nation into civil war. Here indeed was the scene of the last of Hercules' labours; would his good fortune or skill yield him a final triumph?
It is doubtful whether Charles had formed any clear idea of the policy he must adopt, and it is certain that his ignorance of German methods of thought and character and his incapacity to understand religious enthusiasm led him to underrate the stubbornness of the forces with which he had to deal. But his inveterate habit of silence stood him in good stead; Luther regarded with awe the monarch who said less in a year than he himself said in a day. Campeggi, who accompanied Charles on his march, daily instilled in his ear the counsels of prompt coercion; and the death of the politic Gattinara at Innsbruck was so opportune a removal of a restraining influence that Lutherans ascribed his end to Italian poison. It was, however, inconsistent with the Emperor's nature to resort to force before every method of accommodation had been tried and failed. In 1521 he refused to act on the papal Bull against Luther without a personal attempt at mediation; in 1530 he would not proceed against the Protestants by force of arms until he
