In early 1828, Feodora married Ernst I, Prince of Hohenlohe-Langenburg (1794–1860), at Kensington Palace. The match was arranged by Queen Adelaide of Great Britain, as Prince Ernst I was her first cousin. Prior to that, she had only met him twice. After their honeymoon, she returned to the German Confederation, where she lived until her death in 1872. The prince had no domain, however, as the principality had been mediatised to Württemberg in 1806. The couple lived in a large and uncomfortable castle, Schloss Langenburg.
