Cecilia of Sweden (Swedish: Cecilia Gustavsdotter Vasa) (16 November 1540 in Stockholm – 27 January 1627 in Brussels), was Princess of Sweden as the daughter of King Gustav I and his second wife, Margaret Leijonhufvud, and Margravine of Baden-Rodemachern as the wife of Christopher II, Margrave of Baden-Rodemachern. She is the most famous daughter of Gustav I, known for a courtship scandal in connection with a sister's wedding and for a lengthy stay in England under Elizabeth I where her first child was born. Biography Early life Cecilia was described as the most beautiful of the daughters of Gustav I, and was frequently mentioned because of her beauty. She has been referred to as somewhat of a Black Sheep of the family, because of the scandals she was involved in. During her early childhood, she, as well as her siblings in the royal nursery, were primarily under the care of her mother's trusted nurse, Brigitta Lars Anderssons, her mother's cousin Lady Margareta and the noble widow Ingrid Amundsdotter.

Ostfriesland was chosen because it was strategically placed toward Denmark, and because the Calvinistic Emden was a rival to Lubeck and a treaty could break the domination of the Hanseatic league in Sweden. In 1557, the trading treaty was completed, and in 1558, Edzard visited Sweden to meet Cecilia and her sister Catherine Vasa and chose one of them to complete the marriage treaty, and Edzard chose Catherine.
