Richard had threatened potential rebellion a couple of time during Henry III's rule, and on this occasion he was particularly unhappy with the Savoyard influence in the English Court, particularly Peter of Savoy, feeling that he was being pushed to the side.

In January 1244, Beatrice negotiated a loan for her husband from Henry of four thousand marks, offering the king five Provençal castles as collateral.

Frederick II, Holy Roman Emperor sent a fleet and James I of Aragon sent an army to seize her, so Beatrice placed herself and her daughter in a safe fortress in Aix, secured the trust of its people then sent 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.

[9] In 1254, as Louis was returning from his crusade by way of Provence, Beatrice petitioned him for a more permanent resolution of the dispute with Charles.

As the year progressed, Henry and his wife were invited to travel to Paris, and eventually all four daughters joined their mother there for Christmas.

[12] While the family was still gathered, Louis IX finally persuaded Beatrice to surrender her claims and control in Provence in exchange for a sizeable pension to be paid to her.

Charles also paid back the loan henry had made to the previous count, clearing his claims in the county.

[13] In 1262, Beatrice was part of the family discussion to try again to bring peace between Henry and Simon de Montfort.

[14] When Henry was captured in 1264, Beatrice's brother Peter II, Count of Savoy took his army to join the efforts to free the king.
