Fulk Fitz Warin
Fulk FitzWarin (also called Fulke or Fouke FitzWaryn or FitzWarren, etc.) (c. 1160–1258) was an English nobleman turned outlaw from Whittington Castle in Shropshire. The historical Fulk, or Fulk III FitzWarin, was a Marcher Lord who rebelled against King John from 1200 to 1203 over his familial right to the estate of Whittington. After his death he was the subject of an "ancestral romance", Fouke le Fitz Waryn, which contains a highly embellished account of his life and family history. The bulk of the narrative is concerned with his period as an outlaw, which has various similarities to the later legends of Robin Hood.
