Tour de Nesle affair

Some of the principal actors in the Tour de Nesle Affair, depicted in 1315, the year after the scandal broke: Philip IV of France (centre) and his family: l–r: his sons, Charles and Philip, his daughter Isabella, himself, his eldest son and heir Louis, and his brother, Charles of Valois.

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 apparently started 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 imprisonments, torture and executions for the princesses' lovers and the imprisonment of the princesses, with lasting consequences for the final years of the House of Capet.
