Isengau (historical)

The title of this article is ambiguous. For further meanings see Isengau

The Isengau is one of the medieval districts often found in historical texts . It extends on the Isen in southeast Bavaria from the Rott to the Alz .

The Isengau drew down on the Isen river. The Isen and Dorfen markets as well as the surrounding villages of the small Vils belonged to him. Most of the southwest, southern and eastern parts of the district court district of Erding also belonged to the Isengau according to the old division.

The first Gaugraf appears in 790–820 Graf Job (Jakob), who comes across in many Freising documents as being wealthy on the Isen. After Graf Job followed Heimo, Tunipald and Erenbert. The western part of the Isengau did not have a count for long. While the lower Gau district came to the Counts of Kraiburg and Ortenburg , the Freising bishops and some noble families came into possession of many estates on the Isen.
