The daughter of Count Otto IV of Burgundy and Countess Mahaut of Artois, she was led to a disastrous marriage by her mother's ambition.

The date and place of her death are unknown; the mere fact that she died was simply mentioned on the occasion of her husband's third marriage in April 1326.

The Countess of Artois was proud of this achievement and quickly started negotiating her younger daughter's marriage to Charles, King Philip's third son, offering a huge dowry.

Their heads were shaven and both were sentenced to life imprisonment underground in Château Gaillard, while the d'Aunays were condemned to death and duly executed.

[10] Blanche thus became queen of France and Navarre, but she remained imprisoned and not crowned; at Charles' request, Pope John XXII declared their marriage null and void on 19 May 1322.

The date of her eventual death is unknown; the Pope mentioned her as dead in a document of 5 April 1326 issuing a dispensation for the marriage of her former husband and Jeanne d'Évreux.

[9] Blanche is a character in Les Rois maudits (The Accursed Kings), a series of French historical novels by Maurice Druon.
