There are no contemporary sources about Widukind's life or death after his baptism. Historian Gerd Althoff assumed that he was imprisoned at a monastery—a fate that happened to other rulers deposed by Charlemagne. He tried to identify Reichenau Island as a likely location where Widukind may have spent the rest of his life but his results are inconclusive and widely rejected.
