House of Barcelona
In reality the marriage gave the House of Barcelona extensive interests in Occitania and put it in conflict with the Counts of Toulouse, with whom a partition of Provence was signed in 1125, shortly before Douce's death. Her death inaugurated a period of instability in Provence. A cadet branch of the House of Barcelona was set up to rule, but a disputed succession opened up the Baussenque Wars (1144–1162), which terminated in Provençal victory.
