In 1756, Queen Louisa Ulrika planned a coup d'état to depose the parliamentary system of the Age of liberty with a restoration of an absolute monarchy. To finance the coup, Louisa Ulrika removed the diamonds from the queens' crown, replaced them with crystals, and pawned the diamonds in Berlin in Prussia to finance her coup. Ulrika Strömfelt, however, was a supporter of the Hats and not in favor of a restored absolute monarchy. According to unconfirmed tradition, Ulrika Strömfelt informed the Riksdag that part of the crown jewels was missing and pawned in Germany. This information led the government to demand an inventory of the crown jewels, which initiated the exposure and failure of the Coup of 1756. A different source claims that it Ulrika Strömfelt informed the foreign office of the Riksdag of the secret correspondence between the Queen and her brother, Frederick the Great. Either way, this led to the exposure of the coup. As a recognition of the act, she was awarded a pension of 2.000 riksdaler in silver and the title "Ständernas dotter" by the Riksdag. After the failed coup, she lost the confidence of the Queen, and left court. She was, however, not dismissed, but asked herself to be relieved of her position, officially because of health reasons. That a maid of honor left her position and applied for a pension from the foreign branch office of the Riksdag was unique. Her application was granted, and the pension granted her amounted to double as much as was what usually granted the widow of a riksråd. The Queen stated that the reason Strömfelt left court was that she was a friend of Carl Gustaf Tessin and "all the notables of the Hat's Party, who, under the very eyes of the Queen, held rendez-vous at the parlor of this Chief Maid of Honor". According to Count Axel von Fersen the Elder, she "was now forced to leave court because of the plots of others", and he pointed out the Queens new favorite Ulrika Eleonora von Düben as responsible: von Düben was promoted to the post of Chief Maid of Honor after Strömfelt.
Later life
In 1756, the year she left court, Ulrika Strömfelt married the Over-Governor of Stockholm baron Carl Sparre. The marriage is described as happy despite the constant infidelity of her spouse. In 1777, she returned to court and succeeded Anna Maria Hjärne as Överhovmästarinna to the new Queen, Sophia Magdalena of Denmark with Charlotta Sparre as her deputy, a post she retained until her death. Ulrika Strömfelt has been said to have a "peculiar position" in the diaries and memoirs of the time, because there are no negative remarks about her personality and character, and she is unanimously described as respectable, sensible and as an ideal of contemporary femininity.
