Leo X. died in 1521 and was succeeded by Adrian VI. (1522-3), a former tutor of the Emperor. As a Hollander it might be anticipated that his representations to the German princes would prove more effective than those of his Italian predecessor, particularly as not even his worst enemies could discover anything worthy of reproach either in his principles or personal conduct. Convinced that Luther's only chance of winning support lay in his exaggerated denunciations of real or imaginary abuses, he determined to bring about a complete reform, first in Rome itself and then throughout the entire Christian world.
Owing to his ill-disguised contempt for all that was dear to the heart of the Humanist Leo X., and to the severe measures taken by him to reduce expenses at the Roman Court, he encountered great opposition in Rome, and incurred the dislike both of officials and people.
When he learned that a Diet was to be held at Nurnberg (1522) to consider plans for the defence of the Empire against the Turks who had conquered Belgrade, he despatched Chieregati as his nuncio to invite the princes to enforce the decree of Worms, and to restore peace to the Church by putting down the Lutheran movement. In his letters to individual members of the Diet and in his instructions to the nuncio, which were read publicly to the assembled representatives, Adrian VI.
admitted the existence of grave abuses both in Rome itself and in nearly every part of the church.[26] He promised, however, to do everything that in him lay to bring about a complete and thorough reform.
These admissions served only to strengthen the hands of Luther and his supporters, who pointed to them as a justification for the whole movement, and to provide the princes with a plausible explanation of their inactivity in giving effect to the decree of Worms. The princes refused to carry out the decree of Worms, alleging as an excuse the danger of popular commotion. They brought forward once more the grievances of the German nation against Rome (/Centum Gravamina/), insisted on a General Council being called to restore peace to the Church, and held out a vague hope that an effort would be made to prevent the spread of the new doctrine till the Council should be convoked.
The papal nuncio, dissatisfied with the attitude of the representatives, withdrew from the Diet before the formal reply was delivered to him. Adrian VI., cognisant of the failure of his efforts and wearied by the opposition of the Romans to whom his reforms were displeasing, made a last fruitless effort to win over Frederick of Saxony to his side. The news that the island of Rhodes, for the defence of which he had laboured and prayed so strenuously, had fallen into the hands of the Turks, served to complete his affliction and to bring him to a premature grave. He died in September 1523 to the great delight of the Romans, who could barely conceal their rejoicing even when he lay on his bed of death. He was an excellent Pope, though perhaps not sufficiently circumspect for the critical times in which he lived. Had he been elected a century earlier, and had he been given an opportunity of carrying out reforms, as had been given to some of his predecessors, the Lutheran movement would have been an impossibility.
He was succeeded by Clement VII. (1523-34). The new Pope was a relative of Leo X., and, like him, a patron of literature and art. He was a man of blameless life and liberal views, and endowed with great prudence and tact, but his excessive caution and want of firmness led to the ruin of his best-conceived plans and to the failure of his general policy. He despatched Cardinal Campeggio as his legate to the Diet of Nurnberg (1524). Once again the princes of Germany closed their ears to the appeal of the Pope, refused to take energetic measures to enforce the decree of Worms, and talked of establishing a commission to consider the grievances of their nation against Rome, and to inquire into the religious issues that had been raised.
Campeggio, feeling that it was hopeless to expect assistance from the Diet, turned to the individual princes. He succeeded in bringing about an alliance at Ratisbon (1524) between the rulers of Austria, Bavaria, and several of the ecclesiastical princes of Southern Germany for the purpose of opposing the new teaching and safeguarding the interests of the Catholic Church. A similar alliance of the Catholic princes of Northern Germany was concluded at Dessau in 1526. At the same time the princes who were favourable to Lutheran views, notably Philip of Hesse, John, Elector of Saxony, the rulers of Brandenburg, Prussia, Mecklenburg and Mansfeld, together with the representatives of the cities of Brunswick and Mecklenburg, met and pledged themselves to make common cause, were any attempt made by the Emperor or the Catholic princes to suppress Luther's doctrine by force. In this way Germany was being divided gradually into two hostile camps.
