the Black Prince in 1343, the alliance with England unravelled as Edward's coffers emptied and his attentions turned elsewhere. In September 1345 representative of France and Brabant met at the Château de Saint-Germain-en-Laye to sign preliminary agreements, and by a treaty signed at Saint-Quentin, June 1347, Brabant was retained as an ally by France. Margaret was now to marry Louis of Male, who had inherited the title of count of Flanders, but whose power against the Flemish communes was virtually nil. A point of dispute with the count of Flanders had been the Lordship of Mechelen, a strategic enclave within Brabant: it was agreed that it would now come under full Brabançon control. Despite the diplomacy of Edward, John remained true to his French commitments until his death in December 1355. In 1350, Jews were persecuted in Brabant. Family In 1311, as his father's gesture of rapprochement with France, John married Marie d'Évreux (1303–1335), the daughter of Count Louis d'Évreux and Margaret of Artois. They had six children: Joanna, Duchess of Brabant (24 June 1322 – 1406). Married first to William IV, Count of Holland and second to Wenceslaus I, Duke of Luxembourg. Margaret of Brabant (9 February 1323 – 1368), married at Saint-Quentin on 6 June 1347 Louis II, Count of Flanders Marie of Brabant (1325 – 1 March 1399), Lady of Turnhout, married at Tervuren on 1 July 1347 to Reginald III of Guelders. John of Brabant (1327–1335/36), married Marie of France (1326–1333), daughter of King Philip VI of France, but died soon after with no issue, buried in Tervueren. Henri of Brabant (d. 29 October 1349), Duke of Limburg and Lord of Mechelen in 1347. Died young and buried in Tervuren in 1349. Godfrey of Brabant (d. aft. 3 February 1352), Lord of Aarschot in 1346. Also died young and buried in Tervuren. John also had a son born from Maria van Huldenberg, who founded the House of Brant: John I Brant, 1st Lord of Ayseau. In 1355, after all of his three legitimate sons had died, John was forced to declare his eldest daughter Joanna his heiress, which provoked a succession crisis after his death. John III was buried in the Cistercian Abbey of Villers, Belgium. The standard history is Piet Avonds, Brabant tijdens de regering van Hertog Jan III (1312–1356) (Koninglijke Academie, Brussels) 1991.
