Guy of Ibelin, Constable of Cyprus
Guy of Ibelin (1215/1218 – after 1255) was the fifth son of John of Ibelin and Melisende of Arsuf. He served King Henry I as marshal and then constable of Cyprus.
With his brother Baldwin he led Cypriot knights at the 1249 siege of Damietta on Louis IX’s crusade; Joinville called him one of the finest knights of his age and recounted their capture alongside him.
He married Philippa Barlais; their daughter Isabella married King Hugh III, while their sons Balian and Philip each became seneschal of Cyprus. He founded the Ibelins’ Cypriot branch and died after May 1255.
