Frederikke Dannemand was the royal mistress of which King?
Frederick VI of Denmark Frederick VI (Danish and Norwegian: "Frederik"; 28 January 17683 December 1839) was King of Denmark from 13 March 1808 to 3 December 1839 and King of Norway from 13 March 1808 to 7 February 1814. From 1784 until his accession, he served as regent during his father's mental illness and was referred to as the "Crown Prince Regent" ("kronprinsregent"). For his motto he chose "God and the just cause" (Danish: "Gud og den retfærdige sag" ) and since the time of his reign, succeeding Danish monarchs have also chosen mottos in the Danish language rather than the formerly customary Latin.
Steward of the Realm (Denmark) Steward of the Realm (Danish: Rigshofmester) was an office at the Royal Danish Court. With the coronation of Eric VII of Denmark it became an important office, taking over the role of the Seneschal (Danish: Drost) as the de facto prime minister of the country. Prior to that the Rigshofmester had merely been the administrative leader of the Royal Court. The office was abolished with the institution of Absolute monarchy in Denmark in 1660.
