of Guinegate, in modern Enguinegatte, on 7 August 1479. Despite winning, Maximilian had to abandon the siege of Thérouanne and disband his army, either because the Netherlanders did not want him to become too strong or because his treasury was empty. The battle was an important mark in military history though: the Burgundian pikemen were the precursors of the Landsknechte, while the French side derived the momentum for military reform from their loss. According to some, Maximilian and Mary's wedding contract stipulated that their children would succeed them but that the couple could not be each other's heirs. Mary tried to bypass this rule with a promise to transfer territories as a gift in case of her death, but her plans were confounded. After Mary's death in a riding accident on 27 March 1482 near the Wijnendale Castle, Maximilian's aim was now to secure the inheritance to his and Mary's son, Philip the Handsome.

The Belgian historian Eugène Duchesne comments that these years were among the saddest and most turbulent in the history of the country, and despite his later great imperial career, Maximilian unfortunately could never compensate for the mistakes he made as regent in this period. Some of the Netherlander provinces were hostile to Maximilian, and, in 1482, they signed a treaty with Louis XI in Arras that forced Maximilian to give up Franche-Comté and Artois to the French crown. They openly rebelled twice in the period 1482–1492, attempting to regain the autonomy they had enjoyed under Mary. Flemish rebels managed to capture Philip and even Maximilian himself, but they released Maximilian when Frederick III intervened. In 1489, as he turned his attention to his hereditary lands, he left the Low Countries in the hands of Albert of Saxony, who proved to be an excellent choice, as he was less emotionally committed to the Low Countries and more flexible as a politician than Maximilian, while also being a capable general. By 1492, rebellions were completely suppressed. Maximilian revoked the Great Privilege and established a strong ducal monarchy undisturbed by particularism. But he would not reintroduce Charles the
