In 1140, Constance married Eustace IV, Count of Boulogne, son of Stephen, King of England.
The marriage was arranged by her brother, who was in need of allies against Henry II of England, particularly after the latter bolstered his presence in France by marrying Louis's former wife, Eleanor, Duchess of Aquitaine.
After a decade of marriage, Raymond broke from Louis and moved towards a partnership with Frederick Barbarossa.
Constance wrote to Louis, complaining that she was isolated in Toulouse; the courtiers ignored her and her servants did not obey her orders.
[7] Having lost the favour of Louis, Raymond was forced to perform homage to Henry for Toulouse at Limoges in 1173.
