Mathieu de Foix-Comminges

Mathieu de Grailly or Mathieu de Foix (died 1453) was Count of Comminges between 1419 and 1443. He was the fourth son of Archambaud de Grailly, captal de Buch and Isabella, Countess of Foix. Biography He was knighted in 1413 and became a member of the entourage of John the Fearless, Duke of Burgundy. For his loyalty, King Charles VI of France, allied with Philip the Good Duke of Burgundy, gave him Narbonne, of which he couldn't take possession, because it was under control of Dauphin Charles, then at war with his father and Burgundy. At that time, he married Marguerite de Comminges, twenty years older than him, an authoritarian woman who allegedly had her second husband killed in prison. Fearing a similar fate, Mathieu had his wife locked up a few months later in the castle of Bramevaque and governed Comminges alone. Following his brother, he defected from the Burgundian camp to King Charles VII of France, who rewarded him by making him governor of the Dauphiné between 1426 and 1428.
