Catherine of Valois or Catherine of France was Queen of England from 1420 until 1422. A daughter of King Charles VI of France, she married King Henry V of England and was the mother of King Henry VI. Catherine's marriage was part of a plan to eventually place Henry V on the throne of France, and perhaps end what is now known as the Hundred Years' War. But, although her son Henry VI was later crowned in Paris, the war continued.
