Origins

archi- (“arch-, highest”) + dux (“duke”). First attested in the 10th century in reference to Bruno the Great, who ruled simultaneously as an archbishop and a duke, but only current after revival by Rudolf IV of Austria in a forged document, the Privilegium Maius (1358–1359), to justify claims of precedence over other princes of the Holy Roman Empire.
