The King's Daughters (French: Saint-Cyr) is a 2000 period drama film directed by Patricia Mazuy.

In March 1685, Louis XIV’s final wife Madame de Maintenon wishes to set up a boarding school for young daughters of noble families that have fallen on hard times, the Maison royale de Saint-Louis, a school where girls receive a pious but liberal education.

This provokes too much passion among the actors and so Madame de Maintenon asks Racine to write her a play for her students that praises virtue – this proves to be Esther.

Madame de Maintenon decides to impose stricter rules and plunges into religion in an attempt to expiate her past.

She asks an abbot to help her keep students on the right Christian moral path and keep them safe from the world.
