Who married Princess Sophia Of Sweden?

Magnus II of Saxe-Lauenburg (1543 – 14 May 1603, in Ratzeburg) was the eldest surviving son of Duke Francis I of Saxe-Lauenburg and Sybille of Saxe-Freiberg, daughter of Duke Henry IV the Pious. In 1571 Magnus II ascended the throne after his father Francis I resigned due to indebtedness. Two years later Francis I, helped by his other son Francis (II), deposed Magnus II and re-ascended. Magnus' violent and judicial attempts to regain the duchy failed. In 1588 he was imprisoned for the remainder of his life.
