Prince-Archbishopric of Salzburg

The Prince-Archbishopric of Salzburg (Latin: Archiepiscopatus Salisburgensis; German: Fürsterzbistum Salzburg; Erzstift Salzburg; Erzbistum Salzburg) was an ecclesiastical principality and state of the Holy Roman Empire. It comprised the secular territory ruled by the archbishops of Salzburg, as distinguished from the much larger Catholic diocese founded in 739 by Saint Boniface in the German stem duchy of Bavaria.
