Catharina Ebba Horn

Catharina Ebba Horn af Åminne, (27 May 1720 – 12 September 1781 in Jakobsberg), was a Swedish noble and the second official royal mistress of King Frederick I of Sweden from 1745 to 1748.

Catharina Horn was unmarried at an age when most women of the nobility had already wed. She was described as a handsome blonde and was suggested by Erland Broman, who was a known procurer for sexual partners to the monarch.

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.

[3] Carl Johan Aminoff, who career she supported, described her as "... the mightiest in the kingdom, able to acquire what she wanted from the powerful",[4] and that she introduced him to several of her contacts, in which he included the Ambassador of France, Axel von Fersen the Elder, Riksråd Carl Otto Hamilton and General Baron Albrekt von Lantighausen, who in turn recommended him in France at her request.

In the autumn of 1748 after long negotiations, she finally agreed to leave her position as royal mistress of the monarch after having received a great fortune and three estates.
