Guy IV of Saint-Pol

Guy IV of Châtillon-Saint-Pol (born after 1254, died 1317), second son of Count Guy III and Matilda of Brabant, received the County of Saint-Pol from his brother Hugh II in 1292. Philip the Fair made him grand butler of France in 1296, and as governor of Flanders he commanded the rearguard at Courtrai in 1302.

At Mons-en-Pévèle in 1304 he shared in the victory and was credited with saving the king's life; both Philip IV and Louis X made him a testamentary executor. He married Marie of Brittany in 1292 and was buried at Cercamp Abbey in 1317.
