帝国代表者会議主要決議
In the course of the German mediatization of 1803, the prince-bishopric was united with the Free Imperial city of Regensburg and other territories to form the Archbishopric of Regensburg, with Karl Theodor Anton Maria von Dalberg as archbishop. In 1810, the Principality of Regensburg became part of the Kingdom of Bavaria, although it retained archiepiscopal status. This was after the fall of the Holy Roman Empire in 1806 during the War of the Third Coalition.
