James I renounced claims to Fenouillet-du-Razès and Peyrepertuse, with the castle of Puilaurens, the castle of Fenouillet, the Castellfisel, the castle of Peyrepertuse and the castle of Quéribus; moreover he renounced his feudal overlordship over Toulouse, Saint Gilles, Quercy, Narbonne, Albi, Carcassonne (part of the County of Toulouse since 1213), Razès, Béziers, Lauragais, Termes and Ménerbes (enfeoffed in 1179 to Roger III of Béziers); to Agde and Nîmes (their viscount was recognized as the feudatory of the counts of Barcelona from 1112), and Rouergue, Millau and Gévaudan (derived from the inheritance of Douce I of Provence).
James I refused to renounce feudal rights over the County of Foix, initially included in the treaty, when he ratified the document on 16 July 1258, on the grounds that it was not under the overlordship of the king of France.
According to this treaty the daughter of James I, Isabella, would marry Philip, son of Louis IX.
On 17 July, the Aragonese king renounced his hereditary rights to the County of Provence (then an imperial fief) in favor of Margaret, daughter of his uncle Ramon Berenguer IV, Count of Provence (died in 1245) and wife of the French king.
The direct consequence of the treaty was to definitively separate the House of Barcelona from the politics of today's southern France and so, causing the strong cultural and economic ties of the region that became Catalonia with Languedoc to fade progressively.
