Reichsdeputationshauptschluss
On 12 December 1801, as French troops under Napoleon drew near to occupying the city, Archbishop Colloredo fled Salzburg, never to return. In 1803, in the course of the German mediatization, the prince-arcbishopric was secularized, ending the secular rule of Colloredo. Salzburg was awarded instead to the Grand Duke of Tuscany, who had lost his own state in the Napoleonic upheavals. Later, Salzburg was incorporated into Austria (1805), then Bavaria (1809), then finally into Austria again (1816).
