In 1799, three years after her failed betrothal with the King of Sweden, another marital project originated for Alexandra. Previously in 1798, Dukes Ferdinand Augustus and Alexander Frederick of Württemberg who were the brothers of the Empress Maria Feodorovna, arrived in St. Petersburg to serve in the Russian army. They expressed the interest of Austria to join with Russia in a coalition against the rising power of the French Republic and Napoleon, and to cement this alliance, it was decided to arrange a marriage between Alexandra and Archduke Joseph of Austria, Palatine (Governor) of Hungary and a younger brother of Francis II, Holy Roman Emperor.
