Jeanne d'Albret, 1528-72, queen of Navarre (1555-72), daughter of Henri d'Albret and Margaret of Navarre, and mother of King Henry IV of France (Henry III of Navarre). She became queen of Navarre on her father's death. Unlike her consort, Antoine de Bourbon, whom she married in 1548, she remained one of the staunchest leaders of the French Protestants and one of the bitterest foes of the house of Guise.
