Nordthüringgau

Neighboring Saxon counties were Osterwalde and Balsamgau in the north, Derlingau in the west, as well as Harzgau and Schwabengau in the south.Beyond Elbe and Saale it bordered on the Morazena, Ciervisti and Serimunt counties, administrative parts of the vast marca Geronis from 937.Count Christian' s grandson Gero II (d. 1015) was not able to retain Meissen, but in 993 succeeded his uncle Odo as margrave of the Saxon Eastern March.Upon his death, Schwabengau, Harzgau and Nordthüringgau as well as Serimunt were enfeoffed to Esico of Ballenstedt, a maternal grandson of Margrave Odo.After the deposition of the Saxon duke Henry the Lion in 1180, the lands of the former Nordthüringgau were replaced by the Archbishopric of Magdeburg, the Bishopric of Halberstadt and the Altmark territory of Brandenburg.
