The history of Upper Silesia is intertwined with the activities of Silesian priest Konrad Szweda, a victim of persecutions by German Nazism and Soviet communism. This book contains previously unknown letters and secret correspondence of Fr. Konrad Szweda, enriching the literature of personal documents related to World War II. These egodocuments, part of an anthology of invaluable source texts on the human spirit in “inhuman times”, offer historical material for further research on the clergy. Biographical details and factual nuances reveal surprising paradoxes, forgotten contexts, and facts, challenging established stereotypes and inspiring deeper insights into the complex fabric of the past.
