Tour de Nesle Affair

Margaret and Blanche of Burgundy were accused of adultery with the brothers Philip and Walter of Aunay. Joan of Burgundy was accused of knowing about the relationships and failing to reveal them.

The men were executed and the royal women imprisoned or placed under confinement. The scandal cast doubt on the legitimacy of possible heirs and shaped later arguments about succession.

The Iron King and The Strangled Queen make the affair central to the collapse of Philip IV's household and to Louis X's attempt to escape his marriage to Margaret.
