Catholic or Protestant? Most royal houses changed their confession at any given time based on what was most advantageous. The houses of Baden-Baden and Sachsen-Lauenburg converted to Catholicism in the mid-17th century. In times of religious and political conflict, this was how they demonstrated their loyalty to the imperial house. Pilgrimages and adoration of the Virgin Mary were a tradition in both families, but Sibylla Augusta's Bohemian homeland had an especially strong influence on her.
