Although their union was political, the young Margaret developed a genuine affection for Charles. However, he renounced the treaty in the autumn of 1491 and married her former stepmother Anne, Duchess of Brittany, for political reasons. The French court had ceased treating Margaret as their future queen but she could not return to her stepgrandmother's court until June 1493 after the Treaty of Senlis had been signed in May that year. She was hurt by Charles' actions and was left with a feeling of enduring resentment towards the House of Valois.
