We all live in a community, and it was no different for the Jews and Christians of medieval Germany—or was it? This book draws together disparate threads of Christian and Jewish communal development in an effort to give a deeper understanding to the complex tapestry of Jewish and Christian interaction. In the broad examination presented herein, it is possible to compare the general transformations that affected Jews and Christians both as residents of a shared German society and as residents of their own separate communities. Jews and Christians interacted in a variety of ways, in numerous settings, and at a multitude of levels that defy simple categorization. To label late medieval Germany a period of crisis is too simplisitc, the “Reformation” should not categorically be viewed as the central development in the shift between medieval and early modern times. This book seeks to recontextualize the world of Jewish and Christian relations by bringing together divergent sources not often taken together, but equally important, to inform one another and offer a fuller picture of Jewish and Christian notions of each other and themselves than has been possible up to this point.
