Trencavel

The Trencavel were an important noble family in Languedoc during the 10th through 13th centuries. The name "Trencavel," originally a nickname and later a family name, may derive from the Occitan words for "nutcracker" (trenca avelana). The name was traditionally restricted in actual use only to those family members named Raymond, but the last Trencavel viscount, Raymond II, preferred the surname over his given name and adopted it for his charters.

The first well-known member of the family was Ato I, viscount of Albi in the early 10th century. He was followed by five generations of viscounts of Albi in direct father-to-son descent. During this same period the family came to dominate the episcopacy of Languedoc. Each of the viscounts from Ato II on had a younger brother named Frotarius (or Frothaire) who was a bishop, be it of Albi, Cahors, or Nîmes.

In 1069 the three daughters of Peter II of Carcassonne sold their rights to the Counties of Carcassonne and Razès and the Béziers and Agde to Raymond Berengar I of Barcelona for 4,000 mancusos. By marriage to Ermengard, daughter of Peter II, Raymond Bernard, son of Bernard Ato III, became viscount of Carcassonne, having already acquired Nîmes. By 1070 he was viscount of Béziers. His son Bernard Ato IV was viscount of Albi, Béziers, Carcassonne, Nîmes, and Razès. He thus held all the lands of the counts of Carcassonne, but never assumed the comital title. Bernard Ato was formally proclaimed viscount after the death of his mother in 1101.

The sons of Bernard Ato IV divided their inheritance. The eldest, Roger I, took Albi, Carcassonne, and Razès, but had no children. The second, Raymond I took Béziers and Agde. The youngest, Bernard Ato V, inherited Nîmes and married Guilhelma, daughter of William VI of Montpellier. In 1132 Roger and Raymond agreed that on the event of Roger's death without heirs, Carcassonne would pass to Raymond. In 1150 Roger died and his three viscounties all passed to Raymond. After a series of disputes, the viscounty of Agde was divided between Raymond and Bernard Ato, with the latter holding the title. The elder branch of Béziers-Albi-Carcassonne-Razès and the younger of Nîmes-Agde were to remain separate for the remainder of the family's existence. The practical capital of the elder branch was Béziers.
