Готторп
Christian was the eldest son of future king, Frederick I of Denmark, and Anna of Brandenburg. He was born at Gottorf Castle in Schleswig which Frederick I had made as a primary residence. In 1514, when he was just ten years old, Christian's mother died. Four years later, his father remarried to Sophie of Pomerania (1498–1568). In 1523, Frederick I was elected King of Denmark in the place of his nephew, King Christian II of Denmark. The young Prince Christian's first public service after his father became king was gaining the submission of Copenhagen, which stood firm for the fugitive, King Christian II. As stadtholder of the Duchies of Holstein and Schleswig in 1526, and as viceroy of Norway in 1529, Christian III displayed considerable administrative ability.
