Catharina Ebba Horn

Catharina Ebba Horn af Åminne, (27 May 1720 – 12 September 1781 in Jakobsberg), was a Swedish noble, a German Roman Countess and the second official royal mistress of king Frederick I of Sweden from 1745 to 1748. She was one of two official royal mistresses in Sweden. She had no influence over state affairs, but she did patronise careers through her powerful connections and her position.

Catharina Ebba Horn was born as the child of the colonel Baron Krister Horn and Anna Regina Sjöblad and the sister of count Fredric Horn af Åminne and Gustaf Adolf Horn af Åminne. When the official mistress of the king, Hedvig Taube, died in 1744, the royal court was in search for a replacement. The king had at this point a bad reputation because of his open and frequent use of prostitutes from the streets and his alcoholism, but the fact that he had made Hedvig Taube an official mistress, the first one in Sweden, had set an example. Horn, who was unmarried at an age when most women of the nobility were married, and described as a handsome blonde, was suggested by Erland Broman, who was a known procurer for sexual partners to the monarch. The suggestion was supported by the mother of Horn, who was described as a plotting intriguer.

Horn and her mother placed several terms before agreeing to the position of mistress to the king for Catharina Ebba, after having first demanded that he marry her. They demanded, that if the king did not marry her, that the position of mistress should be a formal and officially recognized position in the manner of Hedvig Taube, that she would receive a title in her own right and her own income, in the French form of royal mistress and "queen to the left", which had been granted Hedvig Taube, and finally, that the relationship would not be broken. Initially, they also demanded that Horn should be received at court with rank directly after the women of the royal house, but they gave up this demand after the Crown Princess, Louisa Ulrika of Prussia, stated that if Horn was officially presented with the position as royal mistress, she would not be received at court at all. The rest of the demands were met, however, and in the autumn of 1745, Horn and her mother was given an official welcome to Stockholm by the monarch and three riksråd and given the former palace of Hedvig Taube at Riddarholmen as their residence. In 1746, the king, in his position as Landgrave of Hesse, applied for a noble title from the German Roman emperor for her in the same fashion as he had done for Hedvig Taube, and she received the title of German Roman countess.
