Frederick I was the King of Denmark and Norway. His name is also spelled Friedrich in German, Frederik in Danish and Norwegian and Fredrik in Swedish. He was the penultimate Roman Catholic monarch to reign over Denmark, when subsequent monarchs embraced Lutheranism after the Protestant Reformation. As King of Norway, Frederick is most remarkable in never having visited the country and was never being crowned King of Norway. Therefore he was styled King of Denmark, the Vends and the Goths, elected King of Norway.
During his reign, Frederick was skillful enough to prevent all-out warfare between Protestants and Roman Catholics. In 1532 he succeeded in capturing Christian II who had tried to make a political come-back in Norway. Frederick died on 10 April 1533 in Gottorp, at the age of 61, and was buried in Schleswig Cathedral.
The royal style of King Frederick I was "By the Grace of God, King of Denmark, Sweden and Norway, the Wends and the Goths, Duke of Schleswig, Holstein, Stormarn and Dithmarschen, Count of Oldenburg and Delmenhorst".
