Empress of Austria (1717–1780) and mother of Marie Antoinette. LS in French, one page, 7.5 x 9, March 27, 1761. Letter to her cousin. In full (translated): “It is with much regret that I must forgo the pleasure of being able to support your views with respect to the Grand Mastership of the Teutonic Order. With regard to this matter, I have taken a stand in favor of someone else in whom I have a particular interest. Consequently, I find myself unable to be of use to you on this occasion. I hope that other opportunities will arise which will allow me to follow the inclinations of my sincere friendship for you. I beg you to be assured of this and to understand that there can be no greater guarantee of the affection with which I remain, Monsieur, my cousin, your very affectionate cousin.” In very good condition, with central vertical and horizontal folds, a few mild creases, scattered foxing and soiling, and a trivial tear to the bottom edge. In 1761, upon the death of Clemens August of Bavaria, Prince Charles Alexander, Maria Theresa’s brother-in-law, was named Grand Master of the Teutonic Order. RRAuction COA.
