In Franconia, which was subjected to different rulers in the 16th and 17th centuries, the Christian denominations confronted each other in a number of ways. Both for political and religious reasons, it was important for the Franconian bishops to guide those who were not or no longer Catholics back to Catholicism. One particular obstacle lay in the fact that owing to the power relations and geographical circumstances isolation from Protestant ideas was not possible. The author gives a systematic analysis of the means the Bishops of Würzburg and Bamberg used to pursue their objective. She examines in detail a total of 15 localities, comparing localities within the same chapter and the localities of different chapters. In a second step, she addresses the subjects. What measures did Protestants take to delay or completely avoid a change of denominiation?
