The prolonged absence of the Emperor Charles from Germany, due to his concern in European politics, was one of the principal causes of the growing disturbances. To recall him to Germany and invite him to interfere was the object of a measure taken by certain ecclesiastics at a meeting held at Mayence on November 14, 1525. Delegates from the twelve provinces of Mayence assembled at the instance of the Chapter of Spires. It was a remarkable fact that the bishops themselves, who by the indifference they displayed had, as a body, roused the dissatisfaction of zealous Churchmen, did not attend, but only members of the Chapters. They determined to insist upon their bishops making a stand against the revolutionary Lutheran preaching, to send a deputation to the Pope and the Emperor with an account of the general mischief which had befallen Germany by reason of the apostasy, and finally to urge the Emperor to return to Germany, and meanwhile to name executors for carrying out the orders he might give for the preservation of religion according to law. George of Saxony, Archduke Ferdinand of Austria and the Bavarian Dukes were to be proposed to the Emperor as such executors. The deputation from the Chapters was, however, never sent, owing apparently to the lack of interest displayed by those Chapters which assembled, and by those which were invited but did not send the necessary funds. The zealous Dean of Mayence Cathedral, Lorenz Truchsess von Pommersfelden, found himself practically left single-handed.[593] Upon learning what resolutions had been passed, Luther wrote, in March, 1526, a tract of frightful violence against the “Mayence Proposal”; it was, however, suppressed by the Electoral Court of Saxony, owing to the intervention of Duke George.[594] The Emperor, notwithstanding his promise to arrive speedily, did not reach Germany until 1530, after having achieved great success abroad. He came with the firm intention to oppose the religious revolution with the utmost vigour, and to place the Imperial authority on a firmer footing. Meanwhile, the Courts of Saxony and Hesse, whose sympathies were with the Lutheran party, had, however, at Gotha entered into a defensive alliance which was finally concluded at Torgau on May 2, 1526. The Emperor’s threats, which had become known, did their part in bringing this about; and a further result of the Emperor’s letters against the “wicked Lutheran cause and errors” was, that the Dukes of Brunswick-Lüneburg, Philip of Brunswick-Grubenhagen, Henry of Mecklenburg, Wolfgang of Anhalt and Albert of Mansfeld also joined the league. Luther was greatly rejoiced at this proof of the favour of the Princes, but, as yet, he refused to commit himself on the question as to whether force might be used against the Emperor and the Empire. (See vol. iii., xv. 3.) As a consequence of the Peasant-War the Princes grew in power, while the people lost many rights and liberties which they had previously enjoyed.
