Beatrice of Savoy
Beatrice of Savoy (born before 4 March 1223) was the elder daughter of Count Amadeus IV of Savoy. In March 1233 she married Manfred III, marquess of Saluzzo, and on his death in 1244 she held the regency for their young son Thomas, until Boniface II of Montferrat forced her aside.
In March 1247 she married by proxy Manfred, son of Emperor Frederick II, sealing the Savoy-Hohenstaufen alliance. Their daughter Constance married Peter III of Aragon. Beatrice died in 1258 or 1259, just as her husband seized the crown of Sicily.
