Étampes
The County of Étampes was a French royal appanage south of Paris. In 1337 its count was the infant Louis I, whose father Charles d'Évreux had died in 1336.
Louis was captured at Poitiers in 1356 and later became a hostage for the Treaty of Brétigny. He died childless in 1400, leaving Étampes to John, Duke of Berry. Francis I made it a duchy for Anne de Pisseleu in 1536; royal troops badly damaged the town during the Fronde in 1652.
