Henry_of_Schweinfurt
Henry of Schweinfurt (de Suinvorde; c. 970 – 18 September 1017) was the Margrave of the Nordgau from 994 until 1004. He was called the "glory of eastern Franconia" by his own cousin, the chronicler Thietmar of Merseburg.
Henry was the son of Berthold[1] and Eilika (Eiliswintha or Eila) of Walbeck. His father's parentage is not known with certainty, but he may have been a son of Arnulf, Duke of Bavaria. Henry was Bavarian, whoever his grandfather.
Henry held a succession of countships after his father's death in 980. He was appointed marchio, like his father, of the Bavarian Nordgau in 994. In 1003, he revolted against Henry II of Germany claiming that he had been promised the Duchy of Bavaria in return for his support. The king said that the Bavarians had a right to elect their own duke. Henry allied with Boleslaus I of Poland and Boleslaus III of Bohemia. Nevertheless, his rebellion was quashed and he himself was briefly captive. The king established the Diocese of Bamberg to prevent any further uprisings in the region. The new diocese took over the secular authority of the margrave in the region of the Bavarian Nordgau.
Finally, it was only the joint persuasion of both his saecular and ecclesiastical overlords, Bernard I, Duke of Saxony, and Tagino, Archbishop of Magdeburg, that reconciled him to Henry in 1004. Henry of Schweinfurt did subsequently gain new and old countships before his death in 1017. He was buried at Schweinfurt.
