Battle of Guinegate: French troops of King Louis XI were defeated by the Burgundians led by Archduke Maximilian of Habsburg.

The First Battle of Guinegate took place on 7 August 1479. King Louis XI's French troops, led by Philippe de Crèvecœur d'Esquerdes, were defeated by the Burgundians, led by Archduke Maximilian of Habsburg. The battle was the first in which the innovative Swiss pike square formation was used by a power that was not natively Swiss.

Louis XI, called "Louis the Prudent", was King of France from 1461 to 1483. He succeeded his father, Charles VII. Louis entered into open rebellion against his father in a short-lived revolt known as the Praguerie in 1440. The king forgave his rebellious vassals, including Louis, to whom he entrusted the management of the Dauphiné, then a province in southeastern France. Louis's ceaseless intrigues, however, led his father to banish him from court. From the Dauphiné, Louis led his own political establishment and married Charlotte of Savoy, daughter of Louis, Duke of Savoy, against the will of his father. Charles VII sent an army to compel his son to his will, but Louis fled to Burgundy, where he was hosted by Philip the Good, the Duke of Burgundy, Charles's greatest enemy.

Maximilian I was King of the Romans from 1486 and Holy Roman Emperor from 1508 until his death in 1519. He was never crowned by the Pope, as the journey to Rome was blocked by the Venetians. He proclaimed himself elected emperor in 1508 at Trent, with Pope Julius II later recognizing it. This broke the tradition of requiring a papal coronation for the adoption of the Imperial title. Maximilian was the only surviving son of Frederick III, Holy Roman Emperor, and Eleanor of Portugal. From his coronation as King of the Romans in 1486, he ran a double government, or Doppelregierung with his father until Frederick's death in 1493.
