German Catholicism at War explores the mentalities and experiences of German Catholics during the Second World War. Taking the German Home Front, and most specifically, the Rhineland and Westphalia, as its core focus German Catholicism at War examines Catholics' responses to developments in the war, their complex relationships with the Nazi regime, and their religious practices. Drawing on a wide range of source materials stretching from personal letters and diaries to pastoral letters and Gestapo reports, Thomas Brodie breaks new ground in our understanding of the Catholic community in Germany during the Second World War.
