Spouse: Philippe IV, king of France
Predecessor: Henri I
Reign: 1285 – 1305
Summary: At the age of one, she became the countess regnant of the large County of Champagne and also the queen regnant of the small Kingdom of Navarre straddling the Pyrenees Mountains between France and Spain. Since she was young and unmarried, many local powers attempted to take advantage of her and claim her throne for themselves through marriage. Jeanne and her mother, Blanche, sought refuge in one of those powers: France. At 10 years of age, Jeanne was married to Philippe, the future king of France. All three of her sons—Louis, Philippe, and Charles—would rule France and Navarre in turn while her granddaughter, Jeanne II, would inherit the Kingdom of Navarre a century later when the French line split to the Valois branch of the House of Capet. Her daughter, Isabella, became queen consort of England and her descendants later prompted the Hundred Years' War. Isabella was a bold monarch, but bowed to her husband in the administration of her realms. Still, she was said to have led an army against the Count of Bar when the small county attacked Champagne. She died of a stillbirth in 1305.
