Treaty of Athis-sur-Orge

The Treaty of Athis-sur-Orge was a peace treaty signed on 23 June 1305 between King Philip IV of France and Robert III of Flanders. The treaty was signed at Athis-sur-Orge after the Battle of Mons-en-Pévèle and concluded the Franco-Flemish War (1297–1305).

Despite winning the battle at Mons-en-Pévèle, Philip's kingdom was too financially and militarily drained to take advantage of it. The treaty instead imposed a heavy price.
