(Erzherzog), in Austria and later in Austria-Hungary, a title held by princes of the royal house of Hapsburg, officially conferred in 1453. It stems from a privilege extended to Austrian dukes in the 12th century, by which they were granted rights equal to those of electors, who were also called Erzkurfürsten.
