About Maria Pia of Savoy
Dona Maria Pia was by birth an Italian princess of the House of Savoy and by marriage Queen of Portugal as the wife of King Luís I of Portugal. On the day of her baptism, Pope Pius IX, her godfather, gave her a Golden Rose. Maria Pia was married to Luís on 6 October 1862 in Lisbon. She was the grand mistress of the Order of Saint Isabel. She was the third queen of the House of Savoy on the Portuguese throne after Mafalda and Marie-Françoise of Savoy-Nemours. Obviously Maria was smitten with Luís, as she later wrote "I like him more than his picture." One year after the wedding, at age 15, Maria Pia gave birth to her first son and heir, Carlos, Duke of Braganza. She expressed her sympathy, describing her lost granddaughter as "Very small, but perfect and beautiful, with well-defined features." King Luís died on 19 October 1889 and Maria Pia became queen dowager.
