Biography
John the Younger (Danish: Hans den yngre; German: Johann der Jüngere; 25 March 1545 – 9 October 1622) was a Duke of Schleswig-Holstein-Sonderburg.
Biography
John was born in Haderslev as the fourth child (third son) of King Christian III of Denmark and his wife Dorothea of Saxe-Lauenburg. His elder brother king Frederick II of Denmark allotted him a portion of Schleswig, Sonderburg (today Danish Sønderborg) as his ducal seat. He acted actively in the Danish government, for example supporting his sister-in-law the queen when his nephew Christian IV of Denmark was underage. There were plans for him to marry the dowager queen in 1588 or 1589, repudiating his second, young wife. John died in Glücksburg.
