As a consequence of the 1801 Treaty of Lunéville, the Bishopric of Würzburg was secularized in 1803 and granted to the Electorate of Bavaria. In the same year Ferdinand III, former Grand Duke of Tuscany, was compensated with the Electorate of Salzburg. In the Peace of Pressburg of 26 December 1805, Ferdinand lost Salzburg to the Austrian Empire, but was compensated with the Würzburg territory, Bavaria having relinquished it in return for Tyrol.
