Maria Francisca of Savoy

Dona Maria Francisca Isabel of Savoy (French: Marie Françoise Élisabeth; 21 June 1646 – 27 December 1683) was Queen of Portugal during her marriage to King Dom Afonso VI from 2 August 1666 to 24 March 1668 and, as the wife of Afonso's brother King Dom Peter II, from 12 September 1683 until her death in December that year. She married Afonso VI at the age of 20; because the marriage was never consummated, she was able to obtain an annulment. On 28 March 1668, she married the King's brother Infante Dom Peter, Duke of Beja, who was appointed prince regent the same year due to Afonso's perceived incompetence. She became queen a second time when Afonso died and Peter succeeded his brother, but she herself died three months later.
