The generally good relationship among the four sisters did much to improve the relationship of the French and English kings. It brought about the Treaty of Paris in 1259, where differences were resolved. Beatrice and all her four daughters participated in the talks.

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