$Hohenberg$

The counts of Hohenberg were a Swabian comital house seated at Oberhohenberg Castle. They split from the counts of Zollern, ancestors of the Hohenzollerns, in the mid-twelfth century under their founder Burkhard II. Marriages and inheritances carried the house north, and in 1260 the county was split into Rottenburg and Nagold-Wildberg lines.

The family's greatest match was Gertrude, who around 1245 married Count Rudolf of Habsburg and became Queen Anna when he was elected German king in 1273. Her brother Albert II, Rudolf's councillor, founded Rottenburg about 1280 and was a Minnesinger in the Manesse manuscript before falling in battle in 1298.

Repeated partitions drove the counts into debt: from 1363 shares went to Württemberg and the Rhenish Palatinate, and in 1381 Rudolf III sold the whole county to Duke Leopold III of Austria. Rudolf III died in 1389, and the last sideline ended with Count Sigmund in 1486.
