King Charles sent Baldwin to the northern regions of his kingdom, where
Vikings were making repeated incursions. The Annales Bertiniani mention how the Vikings were driven away in 864 from the
Scheldt estuary and instead sailed further North to the
Rhine. He was oppointed
Margrave of
Flanders. By 870, Baldwin was appointed
lay abbot of
Saint Peter's Abbey in
Ghent and is assumed to have also acquired the county of
Waasland, or parts thereof by this time. Baldwin developed himself as a very faithful and stout supporter of Charles and played an important role in the continuing wars against the
Vikings. He is named in 877 as one of those willing to support the emperor's son,
Louis the Stammerer. During his life, Baldwin expanded his territory into one of the major principalities of
Western Francia. Baldwin died in 879 and was buried in the
Abbey of St-Bertin, near
Saint-Omer. As the monks of Saint-Bertin did not allow women to enter the abbey, not even for burial,
Ælfthryth, his daughter-in-law, decided to bury her husband Baldwin II at the abbey of Saint-Pieter in Ghent. All next four successive counts of Flanders were buried with their spouses at this abbey, making it the
necropolis of the counts of Flanders. In an apparent attempt to give their own abbey more importance, the monks of Saint-Pieter claimed in their eleventh-century
Annales Blandiniensis, that Baldwin was also buried at their abbey. As a result, some confusion rose since over the exact place of his burial. In 1380 the abbot John of Ypres of Sain-Bertain added to the confusion by stating that Baldwin was buried in Saint-Bertain but his heart was interred in Saint-Pieter, which was clearly false since
heart-burial was not yet practised at the time. In the
Annales Blandiniensis Baldwin appeared for the first time with his later nickname "The Iron" ( "ferreus"). The Annales Blandiniensis also mentioned twice that Bladwin was the son of Audacer, and Audacer himself appeared with the title of count and lay abbot in an entry of the year 856. == Issue ==
