Marie of Valois

Marie of Valois (1309–1331) was the eldest daughter of Charles of Valois. In 1323 she married Charles, Duke of Calabria, heir of Robert the Wise of Naples, whose first wife had died childless. In Florence she persuaded the duke to let gentlewomen dress as their means allowed.

Her children included Joanna I of Naples and Maria, Countess of Alba. Her husband died in 1328; she never remarried and died in 1331 during a pilgrimage to Bari.
