فرانسيس الثاني
Dalberg was at Vienna in the Imperial Chancellery when the stance of his uncle, who had taken the French side, ended his diplomatic career with the Austrian court. He was then named Councillor to the King of Bavaria. After the Treaty of Lunéville (9 February 1801) between the French Republic and Francis II, Holy Roman Emperor, he was accredited to Paris as minister of the Margrave of Baden. He negotiated the marriage of the young Charles, Grand Duke of Baden, with Princess Stéphanie de Beauharnais, niece of the Empress Josephine. Talleyrand befriended him and arranged for him to marry Mlle. de Brignoles, one of the ladies of the Empress.
