Clemens August von Galen was a German cardinal and the Bishop of Münster who became a prominent figure of resistance against the Nazi regime. Born into an aristocratic family in 1878, he served as a priest in Berlin before being appointed to lead the diocese in 1933. He is most widely recognized for his courageous public denunciations of the state-sanctioned euthanasia program and the lawlessness of the Gestapo. Although he held conservative political views, his vocal defense of the Church and the sanctity of life made him a symbol of moral opposition during World War II.
