The Dukes of Austria were noble rulers who governed the region of Austria during the Middle Ages. They emerged in the 10th century and played a significant role in the development of the area. The title of Duke was often held by members of the Babenberg dynasty, who expanded their influence and territory through strategic marriages and military conquests. In 1282, the Dukes of Austria became part of the Habsburg dynasty, which would later dominate European politics for centuries. The Habsburgs transformed Austria into a powerful state, leading to the establishment of the Austrian Empire in the 19th century. The legacy of the dukes is still evident in Austria's rich cultural and historical heritage.
