リュネヴィルの和約
In the reorganization of the Holy Roman Empire in the course of the French Revolutionary Wars, much of Further Austria, including the Breisgau, was by the 1801 Treaty of Lunéville granted as compensation to Ercole III d'Este, former duke of Modena and Reggio, who however died two years later. His heir as his son-in-law was Archduke Ferdinand of Austria-Este, the uncle of Emperor Francis II.
