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.
