Francis, Duke of Saxe-Coburg-Saalfeld (in German and fully Franz Friedrich Anton, Herzog von Sachsen-Coburg-Saalfeld, 15 July 1750 – 9 December 1806), was a reigning Duke of Saxe-Coburg-Saalfeld, one of the ruling Thuringiandukes of the House of Wettin. As progenitor of a line of Coburg princes who, in the 19th and 20th centuries, ascended the thrones of several European realms, he is a patrilineal ancestor of the royal houses of Belgium and Bulgaria (and also of Portugal until the death of King Manuel II in 1932 and the United Kingdom until the death of Queen Elizabeth II in 2022), as well as of several queens consort and the empress consort of Mexico in the 1860s.
Francis received a private, careful and comprehensive education and became an art connoisseur. Francis initiated a major collection of books and illustrations for the duchy in 1775, which eventually expanded to a 300,000-picture collection of copperplate engravings currently housed in the Veste Coburg.
Francis was commissioned into the allied army in 1793 when his country was invaded by the Revolutionary armies of France. The allied forces included Hanoverians, Hessians, and the British. He fought in several actions against the French.
Francis succeeded his father as reigning Duke of Saxe-Coburg-Saalfeld in 1800.[1] In the discharge of his father's debts the Schloss Rosenau had passed out of the family but in 1805 he bought back the property as a summer residence for the ducal family.
