Ulrich III von Graben

He was an important member of the court of Frederick III, Holy Roman Emperor, considered as an unswervingly loyal supporter of the Emperor[2] and fulfilled for him various high political and responsible functions in the Duchy of Styria,[3] such as that of imperial Burggraf of Graz and Marburg (Maribor) and Landeshauptmann of Styria.

The genealogist Gabriel Bucelin entitled Ulrich von Graben in his work Germania topo-chrono-stemmato-graphica sacra et prophana as a baron.

[11] In 1462 he succeeded Lord Eberhard VIII von Walsee as Landeshauptmann (state captain / governor) of the Duchy of Styria.

[12] In 1469 Ulrich was enfeoffed as imperial steward with Marburg Castle, which his father had obtained in the trial against the Lords of Walsee.

As such, he was appointed by the Emperor to be the protector of his daughter Kunigunde of Austria, who was staying in Styria, and whose safety was threatened by the Hungarian incursions under Matthias Corvinus.
