Counts of Dillingen

The family originate in Wittislingen, with archaeological evidence of grave goods suggesting the presence of Alamannic nobility from at least the 7th century.

In 954 Arnulf II, Count Palatine of Bavaria, laid siege to Augsburg, damaging the walls such that Bishop Ulrich retired to the fortress of Mantahinga.

Arnulf then laid siege to Mantahinga, but was surprised by a dawn attack by Count Dietpald's relief force.

Ulrich and his forces put up a staunch resistance, providing King Otto time to make his defense.

As the Hungarians departed, Ulrich's brother, Count Dietpald I used the opportunity to lead soldiers to Otto's camp during the night.

[2] Dietpald's son Richwin was given the inheritance of his father as comitatus (i.e. with the rank of comes "count") by Otto the Great.

[3] Hartmann I, son of Hupald IV (d. 1074) was born c. 1040 and in 1065 married Adelheid, daughter of the count of Winterthur.

Many nobles found it difficult to maintain bare essentials at so great a distance from their home territories.

Upon his death in 1286, he likewise bequeathed to the Church of Augsburg his paternal inheritance, including the town and castle of Dillingen, which served as a refuge for future bishops.
