There was a war of succession between John III and Jacqueline. This war was finally won by Philip of Burgundy in 1432, who, in the meantime had inherited John's claims on the county. Philip was a nephew of William VI, who had married a daughter of Philip the Bold of Burgundy. In 1432 he forced Jacqueline to abdicate from Hainaut and Holland on his behalf.
