The Duchy of Austria was a historical territory in Central Europe that emerged in the late 12th century. It became a significant part of the Holy Roman Empire and was ruled by the House of Habsburg, which played a crucial role in European politics for centuries. The duchy was known for its economic development and strategic location along trade routes. In 1453, the Duchy of Austria was elevated to an archduchy, becoming the Archduchy of Austria. This change marked its importance in the region, as it served as the core of the Habsburg lands. The archduchy later expanded to include various territories, influencing the political landscape of Europe.
