María de Molina
María de Molina (märē´ä dā mōlē´nä), d. 1321, queen of Castile, consort of Sancho IV. As regent (1295–1301) for her son, Ferdinand IV, she defended his throne against several pretenders, who were at various times supported by France, Aragón, Portugal, Navarre, and Granada. After Ferdinand's death (1312), she acted as a guardian to her grandson Alfonso XI, while the regency was contested among his other relatives.
