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.
Count Christian of Rosenborg Count Christian of Rosenborg ("Christian Frederik Franz Knud Harald Carl Oluf Gustav Georg Erik"; 22 October 1942 – 21 May 2013) was a member of the Danish royal family. Born Prince Christian of Denmark, he was high in the line of succession until the constitution was changed in 1953 to allow females to inherit the crown, placing his branch of the dynasty behind that of his cousin Margrethe and her two younger sisters. He later gave up his princely rank and his rights to the throne in order to marry a commoner.
