Overview of the role and celebration of Christmas in Nazi Germany
The celebration of Christmas in Nazi Germany included attempts by the regime to bring the Christian religious holiday into line with Nazi ideology. The Jewish origins of Jesus and the commemoration of his birth as the Jewish Messiah was troubling for some members of the Nazi Party and their racialist beliefs. Between 1933 and 1945, some government officials attempted to remove these aspects of Christmas from civil celebrations and concentrate on cultural pre-Christian aspects of the festival. However, church and private celebrations remained Christian in nature. Background.
