Babenberger
The Babenbergs were a noble dynasty who ruled the Margraviate of Austria from the 10th century until their extinction in 1246. Their origins trace back to the Franconian Babenberger family, who were prominent in the Holy Roman Empire. Leopold I of Babenberg, appointed Margrave of Austria in 976, is considered the founder of the Austrian branch. Under their rule, Austria gradually transitioned from a frontier territory to a more settled and prosperous duchy. The Babenbergs consolidated their power, expanded their territories, and fostered cultural development. Notable rulers include Henry II Jasomirgott, who elevated Austria to a duchy in 1156, and Frederick II, the last Babenberg duke. Their reign saw the construction of many churches and monasteries, contributing to the architectural landscape of medieval Austria. The dynasty's male line ended with Frederick II's death without heirs on June 15, 1246, at the Battle of the Leitha River. This event marked the end of their rule and led to a period of dynastic struggle for control of Austria, eventually resulting in the rise of the House of Habsburg.
