Henry, Margrave of the Franks

Henry^[a] (died 28 August 886) was the leading military commander of the last years of the Carolingian Empire. He was commander-in-chief under Kings Louis the Younger and Charles the Fat. His early career was mostly restricted to East Francia, his homeland, but after Charles inherited West Francia in 884 he was increasingly active there. During his time, raids by the Vikings (mainly Danes) peaked in Francia. The sources describe at least eight separate campaigns waged by Henry against the Vikings, most of them successful.

Henry is described in the sources as a Saxon, Frank or Thuringian. His title is given variously as count (Latin comes), margrave (marchensis) or duke (dux). The territory he governed is described variously in the sources as Francia, Neustria or Austrasia, perhaps indicating that his military command covered most of the north of the empire from the Breton March in the west to Frisia and Saxony in the east.
