Maria Francisca of Savoy

Dona Maria Francisca of Savoy was twice queen consort of Portugal as the spouse of two Portuguese kings: Afonso VI and Peter II of Portugal. She first became queen of Portugal at the age of 20 on the day of her marriage to Afonso VI; because the marriage was never consummated, she was able to obtain an annulment. On 28 March 1668, she married Afonso's brother, the Infante Peter, Duke of Beja, who was appointed prince regent the same year due to Afonso's perceived incompetence. Maria Francisca became queen of Portugal for the second time when Peter succeeded his brother as Peter II in 1683 but died herself later that year.
