The Tour de Nesle affair was a scandal amongst the French royal family in 1314, during which Margaret, Blanche, and Joan, the daughters-in-law of King Philip IV, were accused of adultery. The accusations were by Philip's daughter, Isabella. The Tour de Nesle was a tower in Paris where much of the adultery was said to have occurred. The scandal led to torture, executions and imprisonments for the princesses' lovers (knights Gautier and Philippe) and the imprisonment of the princesses, with lasting consequences for the final years of the House of Capet.
