Cine s-a căsătorit cu Elisabeth Magdalena of Pomerania?

Elisabeth Magdalena of Pomerania (14 June 1580 – 23 February 1649), was a Duchess consort of Courland by marriage to Friedrich Kettler.

Elisabeth Magdalena was the daughter of Ernst Ludwig, Duke of Pomerania and of Princess Sophie Hedwig of Brunswick-Wolfenbüttel. She married the Duke of Courland, Friedrich Kettler, on 14 March 1600.

She participated in the politics of the Duchy as the adviser to her spouse during the difficult times when Courland was at war with Sweden and Poland and when there was unrest among the nobility in Courland against the ducal reign. In 1616, her brother-in-law was deposed by the local nobility, and her husband was elected sole ruler of Courland the following year. Elisabeth Magdalena actively participated in this affair. She negotiated with her German relatives to have her brother-in-law rehabilitated, and in 1619, she visited the Sejm in Warsaw to that effect. During the war with Sweden, she became known for her charity, and protected schools and hospitals.

She was childless, and became the foster mother of her brother-in-law's son Jacob Kettler. She actively worked for Jacob to be appointed the successor and heir to the Duchy, an effort which proved to be successful when he succeeded her spouse in 1642. As a widow, she settled at Dobele Castle, where she died.

Frédéric I^er Kettler (allemand : Friedrich I. Kettler ; letton : Frīdrihs I Ketlers ; 25 novembre 1569, Mitau - 17 août 1642) est duc de Courlande-Sémigalie de 1587 à 1595 puis de 1616 à 1642 (entre ces deux règnes, il est duc de Sémigalie). Il règne plus de 55 ans.

Fils ainé de Gotthard Kettler et d'Anne de Mecklembourg-Güstrow (en), il hérite de son duché à sa mort, en 1587 à l'âge de 17 ans et demi. En 1595, il décide de le partager avec son frère Guillaume Kettler qui obtient la Courlande, mais ce dernier est déposé en 1616. Il réunifie donc le duché à cette date.

Marié à Élisabeth-Madeleine de Poméranie, il n'a pas de postérité. Son neveu Jacob Kettler, fils de Guillaume et régent depuis 1638, lui succède.
