The Abensberg und Traun family was first mentioned with
Pernhart de Trune in 1114.
Traun Castle is still today owned by the family. The Trauns are one of the 12 so-called "Apostle Houses", i.e. the families which had already played a historical role during the period of
Babenberg rule of Austria (976 to 1246). They were elevated to
Imperial Counts in 1653, receiving the name
Counts of Abensperg and Traun, after a Bavarian family, the counts of Abensperg, who had a similar coat of arms, and had ruled the county of
Abensberg (Bavaria) from the 12th century until they extinguished with
Niclas, Graf von Abensberg in 1485. Only count Ernst von Abensperg und Traun (1608–1668) was very shortly granted the fief of Abensberg when the Habsburg emperor
Leopold I occupied Bavaria during the
War of the Spanish Succession. From 1656 the Abensperg and Traun family held a seat on the "Swabian counts' bench" of the
Imperial Diet and in 1662 purchased the
Lordship of Eglofs, a lordship with
Imperial immediacy. It was sold to the
Windisch-Graetz family in 1804. To this day, the Abensperg und Traun family owns large estates in Austria, as well as a number of castles and fortresses. == Notable family members ==
