A French princess whose secret second marriage, after a brief reign as England's queen, founded the Tudor dynasty.
Catherine of Valois entered history as a political pawn, a daughter of the mad French king Charles VI married to the victorious English warrior-king Henry V to seal a treaty. She was crowned Queen of England in 1421, but her husband's sudden death from dysentery the following year left her a widow with an infant son, Henry VI, in a foreign and fractious court. As a young dowager queen with royal blood from both sides of the Hundred Years' War, she became a problem for the English nobility, who feared her potential remarriage. Defying them, she formed a relationship with a Welsh courtier, Owen Tudor. Their secret marriage, which produced several children, was a stunning act of personal agency. Though she died at just 35, this union planted the seed for the House of Tudor; her grandson would become Henry VII, the first Tudor king, forever altering England's monarchy.
