Archbishopric of Magdeburg in the context of "Primas Germaniae"

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. The capital of the archbishopric was Salzburg, the former Roman city of Iuvavum.

From the late 13th century onwards, the archbishops gradually reached the status of Imperial immediacy and independence from the Bavarian dukes. Salzburg remained an ecclesiastical principality until its secularisation to the short-lived Electorate of Salzburg (later Duchy of Salzburg) in 1803. Members of the Bavarian Circle from 1500, the prince-archbishops bore the title of Primas Germaniae, though they never obtained electoral dignity; actually of the six German prince-archbishoprics (with Mainz, Cologne and Trier), Magdeburg, Bremen and Salzburg received nothing from the Golden Bull of 1356. The last prince-archbishop exercising secular authority was Count Hieronymus von Colloredo, who was a patron of the Salzburg-native composer Wolfgang Amadeus Mozart.

Magdeburg (/ˈmæɡdəbɜːrɡ/ MAG-də-burg, German: [ˈmakdəbʊʁk] , locally [ˈmaχdəbʊɐ̯ç]; Low Saxon: Meideborg [ˈmaˑɪ̯debɔɐ̯x]) is the capital of the German state of Saxony-Anhalt. The city is on the Elbe river.

Otto I, the Holy Roman Emperor and the founder of the Archbishopric of Magdeburg, was buried in the city's cathedral after his death. Magdeburg's version of German town law, known as Magdeburg rights, spread throughout Central and Eastern Europe. In the Late Middle Ages, Magdeburg was one of the largest and most prosperous German cities and a notable member of the Hanseatic League. One of the most notable people from the city was Otto von Guericke, famous for his experiments with the Magdeburg hemispheres.

The Bishopric of Merseburg was an episcopal see on the eastern border of the medieval Duchy of Saxony with its centre in Merseburg, where Merseburg Cathedral was constructed. The see was founded in 967 by Emperor Otto I at the same time in the same manner as those of Meissen and Zeitz (from 1029: Naumburg), all suffragan dioceses of the Archbishopric of Magdeburg as part of a plan to bind the adjacent Slavic ("Wendish") lands in the Saxon Eastern March beyond the Saale River more closely to the Holy Roman Empire.

The prince-bishopric was re-established by King Henry II of Germany in 1004. It then covered a considerable small territory stretching from the Saale up to the Mulde River and the Margraviate of Meissen in the east.

The Duchy of Magdeburg (German: Herzogtum Magdeburg) was a province of the Margraviate of Brandenburg from 1680 to 1701 and a province of the German Kingdom of Prussia from 1701 to 1807. It replaced the Archbishopric of Magdeburg after its secularization by Brandenburg, giving to the Elector another influential seat to the Reichstag’s College of Princes. The duchy's capitals were Magdeburg and Halle, while Burg was another important town. Dissolved during the Napoleonic Wars in 1807, its territory was made part of the Province of Saxony in 1815.
