The most famous Archbishop was probably the last with princely authority, Hieronymus von Colloredo, who was an early patron of Salzburg native Wolfgang Amadeus Mozart.
In 1803, the Archbishopric was secularized and made an Electorate for the former Grand Duke Ferdinand III of Tuscany (brother of Emperor Francis II), who had lost his throne. The territory was annexed to Austria in 1806, then to Bavaria in 1809, and finally returned to Austria at the Congress of Vienna in 1815.
