For Coullemelle and the nearby villages, the most important event is the Great Peasant Jacquerie in 1358, soon after the defeat of Poitiers and the capture of John the Good by the English. Among the victims of the peasants are the brothers Raoul and Jean de Clermont-Nesle, lords of Coullemelle. On May the 28th, a convoy from the Montdidier region wants to cross the bridge of Saint-Leu-d'Esserent to deliver grains to the Parisians. The Clermont, who are on their land, opposed. Raoul was killed and his brother managed to escape. This is the beginning of an uprising against the nobility which extends in Beauvaisis, especially in the area of Montdidier. The Jacques loot and burn houses of Raoul and his mother in Fontaine and a mansion belonging to Jean in Courtemanche. Many other castles were destroyed by the Jacques, including those of Cardonnois, Mesnil St Firmin, the Herelle, Breteuil, Folleville, La Faloise, Lawarde-Mauger, Fransures, Louvrechy, Mailly-Raineval, Pierrepont and Moreuil, all less than fifteen kilometers from Coullemelle. The revolt was quickly suppressed. June the 10th, everything is over.
