Suilbergau

Suilbergau, also known as Suilbergi,[1] and Sülberggau, was an early medieval county in the province of Eastphalia, in the Duchy of Saxony.

In the west, Suilbergau bordered the diocese of Paderborn, which also had an interest in the area.

Its thingstead was on a hill between what is now Strodthagen and Sülbeck, two villages that now belong to Einbeck.

[3] Suilbergau is mentioned in an early document as "pagus sulbergowe", when it was bestowed on Corvey Abbey, and witnessed by Reinold I of Dassel.

Several men are mentioned in a cartulary written by the monks of Corvey Abbey, on the western border of Suilbergau.
