Marie of Brabant, Queen of France

Marie of Brabant (1254–1322), a daughter of Duke Henry III of Brabant, married Philip III of France in 1274 and was crowned queen in 1275. After the heir Louis died in 1276, she and the chamberlain Pierre de La Brosse accused each other in the ensuing court conflict; at her request Philip had him condemned and executed without trial.

After the Sicilian Vespers of 1282 she pushed Philip to intervene for Charles I of Anjou, helping launch the Aragón Crusade. Widowed in 1285, she lived retired at Les Mureaux until her death. Her children included Louis, Count of Évreux, and Margaret, who married Edward I of England.
