James II of Avesnes

James II of Avesnes was a knight of the Fourth Crusade. He was probably the son of James of Avesnes of Hainaut, who was a leading protagonist of the Third Crusade.
After the Siege of [Constantinople (1204)|conquest of Constantinople] James was one of the followers of Boniface I, [Marquis of Montferrat|Boniface of Montferrat], who had become king of Thessalonica. As part of the forces of Boniface in Greece he fought against Leo Sgouros, a Greek local ruler who had become independent. James received of Boniface in the spring of 1205 the island of Euboea as a fief. James died around 1205 and Euboea was divided into three fiefs for Boniface.
