After his initial period of maintaining independent neutrality from both France and England failed, neighbouring sovereigns in the Low Countries, stimulated as a matter of policy by
Philip VI of France, became John's enemies; among the adversaries of John were the
Count of Flanders, the
prince-bishop of Liège, and counts of
Holland and
Guelders. In 1332, a crisis with the king of France arose over John's hospitality to
Robert, count of Artois, during his journey to eventual asylum at the English court. In response to French pressure John reminded Philip that he did not hold Brabant from him but from God alone. A brief campaign of a coalition of Philip's friends came to a truce, followed by a pact at Compiègne by which John received a fief from Philip worth 2000
livres and declared himself a vassal of France. His oldest son, Jean, was betrothed to Philip's niece,
Princess Marie, and it was agreed that the Brabantian heir would complete his education at the French court in Paris and that Robert of Artois would be expelled from Brabant. The support of France strengthened John's hand with his feudal suzerain, the
Holy Roman Emperor. Though he was technically the Emperor's feudal
vassal, John had been able to ignore
Emperor Louis IV's summons to join him in his intended invasion of Lombardy (1327). The separation of Brabant from the Empire was completed by the Burgundian dukes of Brabant in the fifteenth century. Meanwhile, the princes of the Low Countries settled their differences and formed a coalition against Brabant with a defensive alliance in June 1333. War was briefly brought to the Duchy of Brabant in the summer of 1334, but resolved by a peace brokered by Philip at
Amiens. The French king declared that John had to hand over the town of
Tiel and its neighbouring villages
Heerewaarden and
Zandwijk to the count of Guelders and to betroth his daughter Marie to the count's son, Reinoud. ==The English alliance, 1337–1345==
