Leopold VI (German: Luitpold VI. von Österreich), known as Leopold the Glorious (German: Luitpold der Glorreiche), was the Duke of Styria from 1194 and the Duke of Austria from 1198 to his death in 1230. He was a member of the House of Babenberg. He was also a member of the Chapter of the Cistercian Order. Like his predecessors, he attempted to develop the land by founding monasteries. His most important foundation is Lilienfeld in the Lower Austrian valley of the Traisen river, where he was buried after his death. Besides that, he supported the then highly modern Mendicant Orders of the Franciscans and Dominicans. He is arguably one of the greatest of the Babenbergs.
