The Renaissance movement in Germany is due largely to the influence of Italian scholars and to the teaching of the Brothers of the Common Life in their school at Deventer.[11] The close political relations existing between the German States and the cities of Northern Italy, the mission of Petrarch to the court of Charles IV., the intermingling of German and Italian scholars at the councils of Constance, Florence, and Basle, and the exertions of Aeneas Sylvius, afterwards Pius II., during his term of office as Chancellor of Frederick III., helped largely to promote the study of the classics in Germany, especially when the invention and development of the art of printing had solved the difficulty of procuring manuscripts. As in Italy, Humanism owes much of its success to the generosity of powerful patrons such as the Emperor Maximilian I., Frederick Elector of Saxony and his kinsman, Duke George, Joachim I. of Brandenburg, and Philip of the Palatinate, Bishop John von Dalberg of Worms, and Archbishop Albrecht of Mainz; and as in Italy the academies were the most powerful means of disseminating classical culture, so also in Germany learned societies like the /Rhenana/, founded by Bishop Dalberg, and the /Danubiana/ in Vienna, were most successful in promoting the literary propaganda. But, unlike the Italian, the German revival was assisted largely by the universities. Basle, Erfurt, Heidelburg, and Leipzig showed unmistakably their sympathy towards the movement, and in a short time the programmes of university studies in nearly all the leading centres were modified in accordance with the new ideas of education. Scholasticism was obliged to make way for the classics and natural science. Cologne, alone in Germany, refused to abandon its old system, and, though not unfriendly to the classics, as is evident by the presence of Ortwin Gratius on its list of professors, still it showed itself highly distrustful of the tendencies of some of the Humanist leaders. Yet German Humanism had little, if anything, in common with the flagrant irreligion and immorality of the Italian school. With one or two exceptions German Humanists never assailed revealed religion as such, but attacked instead the prevailing educational system, which they held to be responsible for the widespread ignorance and general decline of the religious spirit. Many of the leading German scholars were exemplary in their moral character and in their loyalty to the Church, and few, even of those who were regarded as hostile, showed any sympathy with Luther once they understood that he aimed at revolt rather than reform.
