Treaty of Melun

The Treaty of Melun was signed in April 1226 between Louis VIII of France and Jeanne of Constantinople. Jeanne was forced into accepting the accord since her husband, Ferrand of Portugal, was captured by the French at Bouvines on 27 July 1214. Based on the terms of the treaty, the Counts of Flanders were forced to subordinate themselves to the French crown. Moreover, no new castles were to be erected below the Scheldt. Ultimately, Jeanne was forced to pay 50,000 livres in order to have her husband released from prison.
