Rudolf IV der Stifter ("the Founder") (November 1, 1339 – July 27, 1365) is a scion of the House of Habsburg and Duke (self-proclaimed Archduke) of Austria and Duke of Styria and Carinthia from 1358, as well as Count of Tyrol from 1363 and first Duke of Carniola from 1364 until his death.
After the Habsburgs get nothing from the decree of the Golden Bull in 1356, he gives order to draw up the "Privilegium Maius", a fake document to empower the Austrian rulers.
