Christiane Eberhardine of Brandenburg-Bayreuth

Christiane Eberhardine of Brandenburg-Bayreuth was Electress of Saxony from 1694 to 1727 and titular Queen of the Polish–Lithuanian Commonwealth from 1697 to 1727 by marriage to Augustus II the Strong. Not once throughout the whole of her thirty-year queenship did she set foot in Poland, instead living in Saxony in self-imposed exile. Born a German margravine, she was called Sachsens Betsäule, "Saxony's pillar of prayer", by her Protestant subjects for her refusal to convert to Catholicism and her loyalty to the Protestant faith. Despite the allegiance of Christiane Eberhardine and her mother-in-law, Anna Sophie of Denmark, to Lutheranism, her husband and son, later Augustus III, both became Catholics, ensuring Catholic succession in the Albertine lands after a century-and-a-half.
