Jacqueline also remarried, but her selection of husband was unfortunate. John IV, Duke of Brabant, stepson of Elisabeth of Görlitz, who succeeded his father Anthony as Duke of Brabant, was chosen to be her second husband; modern historians believed that this decision was widely influenced by Jacqueline's mother and uncle John the Fearless, Duke of Burgundy. On 31 July 1417, two months after William II's death, the betrothal between Jacqueline and John IV took place, and the wedding was celebrated in The Hague on 10 March 1418. However, the union proved to be a failure. The close relationship between the spouses required a papal dispensation, which, although granted in December 1417, was revoked in January 1418 in the Council of Constance due to the intrigues of Jacqueline's opponents, including King Sigismund of Luxembourg. In addition to this, the considerable financial problems of the young Duke John IV and his weak political leadership increased the conflicts inside the marriage.
