The new duke fought in the crusades in Spain, Egypt, and Palestine, but is more celebrated as a lawgiver, a patron of letters, and a founder of many towns. Under him Vienna became the centre of culture in Germany and the great school of Minnesingers. His later years were spent in strife with his son Frederick, and he died in 1230 at San Germano, now renamed Cassino, whither he had gone to arrange the peace between Emperor Frederick II and Pope Gregory IX.
