Individual Details

Birth

After his father's death (1209), Ramon was imprisoned in the castle of Monzón, in Aragon until he was able to escape in 1219 and claim his inheritance. He was a powerful and energetic ruler who added Forcalquier to his domain. Giovanni Villani in his Nuova Cronica had this to say about Raymond:
Count Raymond was a lord of gentle lineage, and kin to them of the house of Aragon, and to the family of the count of Toulouse, By inheritance Provence, this side of the Rhone, was his; a wise and courteous lord was he, and of noble state and virtuous, and in his time did honourable deeds, and to his court came all gentle persons of Provence and of France and of Catalonia, by reason of his courtesy and noble estate, and he made many Provençal coblas and canzoni of great worth

Marriage

Marriage and issue
Beatrice betrothed on 5 June 1219 to Ramon Berenguer IV, Count of Provence; they married in December 1220. She was a shrewd and politically astute woman, whose beauty was likened to that of a second Niobe by Matthew Paris. Ramon and Beatrice of Savoy had four daughters, who all lived to adulthood, and married kings. Their only son, Raymond died in early infancy.[2]
Margaret, Queen of France (1221–1295), wife of Louis IX of France
Eleanor, Queen of England (1223–1291), wife of Henry III of England
Sanchia, Queen of Germany (1228–1261), wife of Richard, Earl of Cornwall
Beatrice, Queen of Sicily (1234–1267), wife of Charles I of Sicily
Raymond of Provence, died young
Beatrice came to England to see her third daughter Sanchia wedded to Richard, 1st Earl of Cornwall, brother-in-law of Eleanor. Beatrice's husband Ramon Berenguer IV was detained by state difficulties which his wife solved by getting a loan from her son-in-law Henry III of four thousand marks.

Widowhood
When Ramon Berenguer had died on 19 August 1245, he left Provence to his youngest daughter. Beatrice's daughter and namesake then became one of the most attractive heiresses in medieval Europe. Various suitors had tried to seize her, so Beatrice of Savoy placed the younger Beatrice in a safe fortress, secured the trust of its people then went to the Pope for his protection. In Cluny during December 1245, a secret discussion, between Pope Innocent IV, Louis IX of France, his mother Blanche of Castile and his brother Charles of Anjou, took place. It was decided that in return for Louis IX supporting the Pope militarily, the Pope would allow Charles of Anjou, youngest brother to the French King, to marry Beatrice of Provence. But Provence was to never go to France outright through Charles. It was agreed that if Charles and Beatrice had children, the county would go to them; if there was no issue, then the county would go to Sanchia of Provence. If Sanchia died without an heir, Provence would go to the King of Aragon.
The generally good relationship between the four sisters also did much to improve the relationship of the French and English kings. It brought about the Treaty of Paris, where differences were resolved. Beatrice and all her four daughters participated in the talks.
Beatrice of Savoy was granted the usufruct of the county of Provence for her lifetime, according to her husband's will. Beatrice outlived her third daughter Sanchia and came close to outliving her youngest daughter Beatrice, who died months after her mother (Beatrice the elder died in January, Beatrice the younger died in September). Beatrice of Savoy died on 4 January 1267.
