Northeim County

The county Northeim was a medieval county near Rittigau on the southwestern foothills of the Harz Mountains with the main town Northeim .

history

Around 950 a family of counts appeared in Northeim for the first time, whose power reached its first high point with Count Otto I, when he was Otto II Duke of Bavaria from 1061-1070 . His son Heinrich the Fette became Margrave in Friesland , his daughter Richenza von Northeim German Empress as the wife of Lothar von Supplinburg .

The property of the Northeimer was on the upper Leine , the Werra and the Weser , the Diemel and the Nethe ( Boyneburg ) and the lower Elbe ; In addition, the Counts of Northeim were bailiffs of Corvey , Gandersheim , Helmarshausen , the St. Blasien family monastery in Northeim, Bursfelde , Amelungsborn and Oldisleben .

After the death of Richenza († 1141), her cousin Siegfried IV. Von Boyneburg († 1144) and the former Margrave of Meißen Hermann II. Von Winzenburg († 1152), this family property became the wife of Richenza's daughter Gertrud von Sachsen († 1143) of Duke Henry the Proud and mother Henry the Lion , and thus inherited to the Guelphs .

Family origin

The origin of the Counts of Northeim is disputed in research. While Reinhard Wenskus has shown family ties to the family of Margrave Gero and the Immedingern , Erich von Brandenburg sees Siegfried (I.) von Northeim as the son of Count Siegfried I of Luxemburg , a thesis that was taken up and worked out by Armin Wolf in 1997. The opposing position is represented in particular by Eduard Hlawitschka .
