An aborted reformation: Germans and the papacy in the mid-fifteenth century

Why did the Reformation not occur in mid-fifteenth century Germany? The Germans had already become very angry with the papacy, and began a movement to force the curia to allow them to reform their own Church in their own way. The curia, which had its own plans for reform, of course refused. Each side began to develop weapons; but the struggle, which came close to a crisis, quickly fizzled. I maintain that the reason was that the Germans, who detested heresy, were unable to focus their anger against the curia sufficiently to carry out their program, chiefly because localism was so strong that no program could be agreed on for more than a few months. The event that brought about the crisis was the Turkish advance in Europe, which both the papacy and the Germans wished to use for their own purposes. Gradually the incipient revolt simmerend down, but the underlying causes remained. Fifty years later, this anger was able to achieve direction, and the stored-up feeling, now focussed, was able to explode.
