 His two duchies became the Cispadane Republic which one year later was merged into the Cisalpine Republic and then into the Napoleonic Kingdom of Italy.Ercole was compensated in 1801 with the small principality of Breisgau in southwestern Germany, whose previous rulers, the Habsburgs, ceded it to him in anticipation of its eventual return to the Habsburgs, since Ercole's daughter Maria Beatrice Ricciarda d'Este was married to a cadet Habsburg, Archduke Ferdinand of Austria-Este.Ercole died in 1803 and Breisgau passed to his daughter and her husband, who in 1806 lost it during the Napoleonic reorganization of the western territories of the defunct Holy Roman Empire to the enlarged and elevated Grand Duchy of Baden.
