Henry the Fat[1] (c. 1055 – 1101),[2] also known as Henry of Nordheim or Northeim, was Count in Rittigau (part of Liesgau) and Eichsfeld from 1083 onwards, and was the Margrave of Frisia from 14 April 1099 until he was murdered in 1101. He was the father of Empress Richenza.
Henry's wife, Gertrude, was the only sister of Egbert II, Margrave of Meissen, whose own marriage remained childless. By the right of inheritance Henry stood to receive Egbert's counties in Frisia on the margrave's death in 1090, though Meissen was granted by the Emperor to another Henry. These Frisian counties, however, had been annexed from Egbert during the latter's rebellion in 1089 and were being administered by Conrad, Bishop of Utrecht. When Conrad was assassinated on 14 April 1099, the Emperor finally bestowed the counties on Henry.[8] Henry immediately tried to regulate Frisian shipping and ignored the privileges granted to the town of Staveren. The Church, feeling threatened by Henry, allied with the merchant class and the townsmen. Though they received him on seeming friendly terms, he perceived their threat and tried to flee by boat.[9] His ship was attacked at sea and sunk, Henry was killed, but his wife escaped the assault.[10] The day of his death is not known precisely, but he was buried in Bursfelde on 10 April 1101.
