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.[1] 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.[2] The treaty instead imposed a heavy price.[2]
Treaty terms
Based on the terms of the treaty, the cities of Lille, Douai, and Orchies, were allocated to the French crown.[3] In return, Flanders was allowed to preserve its independence with the Count of Flanders but as a Fiefdom of France. At the same time, the treaty provided a yearly penalty of 20,000 pond and reparations of 400,000 pond paid by the Flemish.[2] They also were required to furnish Philip with 600 knights, while tearing down the fortresses around large cities.[2] Bruges was mandated to send 3,000 individuals on pilgrimage while 1,000 of them were required to travel overseas.[2]
Robert III of Flanders faced an impossible task of placating the French monarchy while trying to keep the Flemish cities from revolting.[2] It was not until after 1309, that any of the monetary reparations were paid.[4]
Uprisings following the treaty
Because the financial terms of the treaty were so hard, it was met with wide disapproval in Flanders.[2] In June 1310, Pope Clement V, under pressure from Philip, stated those that failed to fulfill the terms of the treaty would be excommunicated.[5] Aardenburg and Ghent suffered riots in 1311, due to tax collection.[4] Flemish farmers and middle class were hit the hardest that the Peasant Revolt in Flanders broke out in 1323.[6] The peasant revolt turned into a popular uprising that dominated politics for 5 years in the county of Flanders. It was crushed in 1328 with the Battle of Cassel.
