The battle of Mons-en-Pévèle is part of the affairs of Flanders which had a considerable role during the reign of Philip IV the Fair. Relations between the county and the kingdom were often conflicting. On the one hand, the King of France continued the work of Philippe Auguste and Louis IX, forging a state whose authority suffered no challenge from his vassals; on the other hand, the wealthy county of Flanders cherished the hope of loosening the grip of royal power. Political and military conflicts followed one another. The county was invaded, occupied, then revolts put the king of France in difficulty until the battle of Kortrijk (1302) which was a real disaster for the royal army. Philippe le Bel decided to end it. The year 1304 marked the year of revenge: he won the Battle of Zierikzée at Sea on August 10 and 11, then the Battle of Mons-en-Pévèle on August 18. This victory resulted in a treaty in 1305.
