Andreas von Graben

In 1423 he was Burgrave of Landskron, and in a military conflict between Count Hermann III von Cilli with the Burgamt, the city of Villach, he also led the Cillian forces against the surrounding area, which was in fiefdom of the bishops of Bamberg.

[10] In 1433, Von Graben served as a captain (Hauptmann, a sort of stadtholder) of the former Ortenburg Estate which belonged to the Counts of Celje.

[11][12][13] In 1436, Count Frederick II of Celje gave Andreas von Graben the burgraviate (a sort of viscount)[14] and rulership of Sommeregg as a pledge.

In 1442 the Cillier gave him and his legitimate sons Sommeregg with the usual castle hat for life, which he chose as his new family residence [15][16] In 1445 he was involved in the fierce feud between Count Henry VI of Gorizia and his wife Catherine von Gara and later supported the military campaigns of his bellicose liege lord Count Ulrich II of Celje.

He enforced a settlement with the Counts of Gorizia, whereupon Andreas von Graben had to renounce his conquests and also lost his office as stadtholder of the Ortenburg estates.
