The Duchy of Salzburg was a historical territory in Central Europe, primarily located in what is now Austria. It was established in the early Middle Ages and became a significant ecclesiastical principality, ruled by the Archbishops of Salzburg. The duchy was known for its rich cultural heritage and played a vital role in the spread of Christianity in the region. In 1803, the Duchy of Salzburg was secularized and incorporated into the Austrian Empire. Its capital, the city of Salzburg, is famous for its baroque architecture and as the birthplace of the composer Wolfgang Amadeus Mozart. Today, the region is a popular tourist destination, attracting visitors with its historical sites and stunning landscapes.
