The history of the Kriegsarchiv, which today constitutes the fourth section of the Austrian State Archives, began in 1711, when, on the initiative of Prince Eugene of Savoy, then president of the aulic war council, the Hofkriegsrätliches Kanzleiarchiv (the aulic war council chancellery archive), or, to use the full title, the Archivum bellicum, Hofkriegsrätliches Archiv, was established. In line with practices in the other court offices, this archive was to preserve all the documents accumulated by the aulic war council since its founding in 1556. In instructions dated April 4, 1711, Bernhard Rosenbaum, the first archivist of the newly-founded repository, was charged with arranging all documentary materials at hand in an orderly manner. At the same time, he was instructed to make lists of the important documents in the archive so that he could readily give out information about military events and organizational matters. Thus, from the very outset, the personnel of the archive was assigned the very important duty of collecting and making available for the army information about past military experiences.
