Although the abbey lost its political power, it kept its possessions. Ebringen with Norsingen and Neuravensburg, located in the Holy Roman Empire, remained as the sole dominions. Prince-Abbot Vorster left St Gall and went into exile. In 1801 Ebringen's manor house became his main residence in exile. In the same year, Austria lost the Breisgau to the Duke of Modena Ercole III (Hercules III) after the Treaty of Campo Formio, so Ebringen got a new suzerain. Ercole got his new territory as compensation for the loss of his Italian possessions, but he was not willing to accept it in the first time. So the region remained Austrian until April 1803. Ercole never visited his new duchy and died already in October 1803. Heir was the husband of his daughter Maria Beatrice, Ferdinand Charles of Austria, uncle of Emperor Francis, so the region remained Habsburgian - now ruled by the cadet branch Austria-Este - and de facto Austrian, as the new ruler lived at the imperial court in Vienna. In the German mediatisation of 1803 the abbey St Gall lost Neuravensburg, so Ebringen and Norsingen were its last dominions. In Switzerland the canton of Saentis was dissolved in March 1803. Parts of it formed the new canton of St Gall. On 8 May 1805 the new canton dissolved the monastery of St Gall and confiscated its possessions. As Ebringen was situated in an Austrian controlled area, the canton wasn't able to do so in Ebringen. Vienna didn't accept St. Gall's claims for Ebringen and claimed Ebringen for itself. Only with regard to the abbot being in exile in Ebringen the direct local administration hadn't been taken over by Austria-Este, the canton was told. But in September 1805 Vorster left Ebringen when a French army threatened to invade the Breisgau. The canton of St Gall could take control over Ebringen, after a French army occupied the Breisgau in the same month. In the Peace of Pressburg of December 1805 the House of Habsburg and Austria also de jure lost control over the Breisgau. It was decided that the whole region should become part of the new Grand Duchy of Baden. Baden took over the rule on 15 April 1806. But the territorial status of some dominions in the Breisgau was disputed. Although Baden saw itself as suzerain, it respected St Gall's possession of Ebringen, while most other mediate territories were dissolved. So
