Confederation of the Rhine
After the dissolution of the Holy Roman Empire in 1806, Dalberg together with other princes joined the Confederation of the Rhine. He formally resigned the office of Arch-Chancellor in a letter to Emperor Francis II, and was appointed prince-primate of the Confederation of the Rhine by Napoleon. At that point, the " of Frankfurt was included among his territories. Not long after, Dalberg appointed Napoleon's uncle, Cardinal Fesch, coadjutor in his archdiocese (an action for which he had no canonical rights).
