Spanning over two centuries of protestant missionary activity, this book examines the ways in which theological, social, and racial themes intertwined in the relationship between the Christian majority in Prussia and the Jewish minority in its midst. Making comprehensive use of the archives and publications of the various Prussian institutions and societies which set out to convert Jews to Christianity, this study sheds light on a facet of Jewish-German history which has been overshadowed by the ultimate tragedy of the Holocaust.
