[PAR] [TLE] Frederick I of Denmark [SEP] Frederick I (7 October 1471 – 10 April 1533) 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". [PAR] [TLE] Magnus III of Mecklenburg-Schwerin [SEP] Magnus III of Mecklenburg (July 4, 1509 in Stargard – January 28, 1550 in Bützow) was a member of the House of Mecklenburg who was the first Lutheran administrator of the Prince-Bishopric of Schwerin, nevertheless referred to as prince-bishop.  He was the son of Henry V, Duke of Mecklenburg and Ursula of Brandenburg.  He was elected bishop in 1516, but due to his minority and lack of papal confirmation, he only began ruling as an administrator in 1532.  He introduced the Reformation the next year.  He married Elizabeth daughter of Frederick I of Denmark and Sophie of Pomerania.  They had no children.
