Lutheran church was organised on a similar plan in Hesse and Brandenburg and in many of the free cities such as Nurnberg, Magdeburg, Bremen, Frankfurt, Ulm, etc. By these measures the separation was completed definitely, and a certain amount of unity was ensured for the new religion. Meanwhile, how fared it with the Emperor and the Pope? Shortly after the Diet of Nurnberg (1522) Charles V. left Germany for the Netherlands. Owing to the troubles in Spain and the long drawn out war with France he was unable to give any attention to the progress of affairs in Germany. The administration of the Empire was committed to three representatives, the ablest of whom was the Elector Frederick of Saxony, the friend and patron of Luther. The result was that Luther had a free hand to spread his views notwithstanding the decree of Worms. 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.
