Royal Danish Naval Academy in the context of "Frederik IX of Denmark"

Haakon VII (Norwegian pronunciation: [ˈhôːkʊn]; born Prince Carl of Denmark; 3 August 1872 – 21 September 1957) was King of Norway from 1905 until his death in 1957. Having reigned for nearly 52 years, he was the second longest-reigning monarch in Norwegian history, after Christian IV.

He was born in Copenhagen during the reign of his grandfather, King Christian IX of Denmark; he was named Carl at birth and was the second son of the Crown Prince and Crown Princess of Denmark (later King Frederick VIII and Queen Louise). Carl was educated at the Royal Danish Naval Academy and served in the Royal Danish Navy. After the 1905 dissolution of the union between Sweden and Norway, he was offered the Norwegian crown. Following a monarchy referendum, he accepted the offer and was formally elected King of Norway by the Storting and took the Old Norse name Haakon, thus ascended the throne as Haakon VII, becoming the first independent Norwegian monarch since Olav IV in 1387.

Frederik IX (Christian Frederik Franz Michael Carl Valdemar Georg; 11 March 1899 – 14 January 1972) was King of Denmark from 1947 to 1972.

Frederik was born into the House of Glücksburg during the reign of his great-grandfather King Christian IX. He was the first child of Prince Christian of Denmark and Princess Alexandrine of Mecklenburg-Schwerin (later King Christian X and Queen Alexandrine). He became crown prince when his father succeeded as king in 1912. As a young man, he was educated at the Royal Danish Naval Academy. In 1935, he married Princess Ingrid of Sweden. They had three daughters: Margrethe, Benedikte and Anne-Marie. During Nazi Germany's occupation of Denmark, Frederik acted as regent on behalf of his father from 1942 until 1943.
