In 1487, his daughter Kunigunde married Albert IV, Duke of Bavaria. Albert illegally took control of some imperial fiefs and then asked to marry Kunigunde (who lived in Innsbruck, far from her father), offering to give her the fiefs as a dower. Frederick agreed at first, but after Albert took over yet another fief, Regensburg, Frederick withdrew his consent. On 2 January 1487, however, before Frederick's change of heart could be communicated to his daughter, Kunigunde married Albert. A war was prevented only through the mediation of the Emperor's son, Maximilian.
