for their losses to France by distributing the Church land among them, so Dalberg lost a couple of territories there (among other things, Constance), though (due to the prominent position of the Arch-Chancellor of the Empire, and perhaps also due to his personality and skilled diplomatics), he would be the only spiritual prince to retain at least some territory for temporal government: the Mainzian lands around Aschaffenburg, the (Free Imperial City) of Wetzlar (with the rank of a Countship) and the Principality of Regensburg containing the Imperial City, the bishopric, and some independent monasteries. (Regensburg was also where the Imperial Deputation had taken place.) In addition, he was designated Archbishop of the (former Salzburg suffragan) Regensburg, to which (spiritually now) the former Mainz lands on the right bank of the Rhine, and the former Mainzian suffragans were attached. This was, of course, the decision of a state authority which, in its spiritual part, could not take effect until ratified by the Pope; in any case, Regensburg's bishop, Schroffenberg, was still alive at the time. So, Dalberg did not exercise spiritual authority in the older part of the Regensburg diocese until Bishop Schroffenberg died, at which point he made himself elected vicar capitular of the diocese; finally, on February 1, 1805, he received the papal assent and was Archbishop of Regensburg. Prince-primate of the 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). After the Treaty of Schönbrunn (1810), he was elevated by the French to the rank of Grand Duke of Frankfurt. This greatly augmented Dalberg's territories, although he had to cede Regensburg to the Kingdom of Bavaria. As Grand Duke of Frankfurt he ordered all restrictions on the Jews of Frankfurt lifted. This was opposed by the Lutheran town council, until 1811, when Dalberg issued a proclamation ending the requirement that Jews live in the ghetto or pay special taxes. In 1813 he ceded all his temporal offices to Napoleon's stepson Eugène de Beauharnais,
