Margaret, Countess of Anjou
Margaret of Anjou (1273–1299) was countess of Anjou and Maine in her own right. A daughter of Charles II of Naples, she married Charles of Valois, son of King Philip III of France, at Corbeil in August 1290; her father ceded Anjou and Maine to Charles as her dowry.
Her children included Philip VI, the first Valois king of France, and Charles II of Alençon, killed at Crécy in 1346, long after her death on 31 December 1299.
