Anne Sophie von Reventlow (; 16 April 1693 – 7 January 1743) was Queen of Denmark and Norway from 1721 to 1730 as the second wife of Frederick IV of Denmark and Norway. Early life Countess Anna Sophie von Reventlow was born in Clausholm castle as the youngest daughter of Count Conrad von Reventlow, who served Frederick IV as Grand Chancellor, and his second wife Sophie Amalie von Hahn (1664-1722). About Anna Sophie's childhood nothing is known apart from the fact that her upbringing was educationally inadequate: Answered letters show that she made clumsy use of Danish, French and German. She was described as beautiful and lively, with "black, fiery eyes." Spouse by bigamy In 1711 the King encountered Anne Sophie at a masquerade ball in Koldinghus, where the royal family resided that season. He wanted her to become his mistress, which her mother refused to allow. The king abducted her on 26 June 1712 from her parents' estate, Clausholm, with the apparent support of her half-sister Christine Sophie and her husband Count Ulrik Adolph Holstein of Holsteinborg (1664-1737). The King took her to Skanderborg castle, where they were married morganatically in a wedding ceremony conducted by Thomas Clausen. The King's wife was still alive, which made the wedding bigamy. However, he had committed bigamy once before, with Elisabeth Helene von Vieregg. The church authorities had not forbidden the king to engage in polygamy, as there were doctrines based on the biblical polygamy of Hebrew patriarchs. The king installed Reventlow in a house on Bag Børsen (present day Slotsholmsgade 8), close to Christiansborg Palace, in Copenhagen. She was given the title Duchess of Schleswig. In 1713, she was granted Vallø as a fief. Her mother, however, did not support the marriage and did not reconcile with her daughter until 1718. Anna Sophie was supported by her sister Ulrike Eleonora and her brother-in-law, Count Ferdinand Anton of Danneskjöld-Laurvigwhom, whome she often visited. As the king preferred to spent time in the house of Anna Sophie rather than with the reclusive queen, her home gradually became well frequented by the members of nobility who sought the king's favor. The king did not wish to be so public about the bigamy as such, and Anna Sophie was by many regarded as merely his official mistress.
