Aimery II was killed at the
Battle of Fraga on July 17, 1134, fighting against the
Almoravids along with
Alfonso I of Aragon. Aimery left only two underaged daughters as his heirs, Ermengarde and her half-sister Ermessinde (daughter of Aimery's second wife, also named Ermessinde). Aimery had at least one son, also called Aimery, attested in numerous
charters, but this son predeceased him (c. 1130). Thus, the approximately five-year-old Ermengarde inherited the viscounty of
Narbonne upon her father's death, which occupied a strategic place in the politics of
Languedoc: it was desired by the
counts of Toulouse, the
counts of Barcelona, the
Trencavel viscounts of
Carcassonne, and the
lords of Montpellier. '' minted by Alphonse at Narbonne during the minority of Ermengarde (1134–1143) bearing the obverse inscription DUX ANFOS and on the reverse CIVI NARBON In 1142,
Alfonso Jordan, Count of Toulouse, whose wife Faydid of Uzes had either recently died or been repudiated, attempted to marry the now-adolescent Ermengarde. In reaction to this prospect, which overturned the balance of power in the region by adding Narbonne to the direct control of Toulouse, a coalition of Occitan lords led by
Roger II of Béziers, viscount of
Carcassonne,
Béziers,
Albi and
Razès, formed to oppose Toulouse, and arranged the marriage of Ermengarde with a vassal of Roger II,
Bernard IV of Anduze. Alfonso was defeated by the coalition and taken prisoner, and was forced to make peace with Narbonne and restore Ermengarde and her new husband to the viscounty before being released. ==Political activity==
