Queen Kristina I of Sweden, Northern Norway and Mecklenburg (from where her Obodrite dynasty origined) was born in 1643 as the daughter and only child of Erik XVII of Sweden and his wife. She succeeded her father when he died in 1672. He even had changed the law of succession in Mecklenburg for her. For some time (since 1680/81), she was the effective ruler of Brandenburg-Silesia and Franconia-Pomerania (which had no capable native prince). In this position, she influenced the election of Francisco II of Sicily for Roman king, instead of François V. (She herself wasn't electable.)
