Anne of Brittany
However, Charles and his sister wanted her inheritance for France. So, when the former came of age in 1491, and taking advantage of Maximilian and his father's interest in the succession of their adversary Mathias Corvinus, King of Hungary, Charles repudiated his betrothal to Margaret, invaded Brittany, forced Anne of Brittany to repudiate her unconsummated marriage to Maximilian, and married Anne of Brittany himself.
