This volume, dedicated to Hans-Jurgen Goertz (Hamburg University) on the occasion of his sixtieth birthday, brings together fourteen historical and theological essays dealing with the theme of outsiders, non-conformists, and social and religious movements in the German-speaking world between the Late Middle Ages and the Early Modern era. Taking the concept of 'border' as its departure point, the volume offers a kaleidoscope of theoretical and historical analysis, including such topics as the Anabaptist rule in Munster, a civil revolt against the Jews in Worms, and the limits of tolerance in the thinking of Martin Luther. The essays are preceded by an interview with Hans-Jurgen Goertz.
