Notes :

⁽¹⁾In 1153, after conquering numerous important cities and fortresses south of his domains, Ramon Berenguer IV of Barcelona had to ensure not only their defence, but also their repopulation by Christians. He therefore entrusted the Knights Templar with these two missions in a large part of these regions. This mission was sealed in one of the most important donations that the Knights Templar would ever receive, namely the donation of Miravet Castle and numerous other estates located along the Ebro Valley. The Order of the Temple was then put in charge of the security of this entire area against incursions by the Almohads. This donation was undoubtedly also compensation for the "Testament of Alfonso I "the Battler", who had bequeathed his kingdom to the Orders of the Temple, the Hospital and the Holy Sepulchre in 1134. This bequest was rejected by the Aragonese nobility, who had propelled Ramon Berenguer IV to the throne. With this donation, known as the "Miravet", the count obtained the assurance that the Order of the Temple would officially and definitively renounce all claims to the crown of Aragon.

⁽²⁾Raimond-Bérenger (Ramon-Berenguer) IV of Barcelona, known as "the Saint". He was born in Barcelona in 1113 and died in Borgo San Dalmazzo, Italy, in 1162. He was Count of Barcelona, Girona, Cerdanya and Osona, Ribagorce and Prince of Aragon. He was the son of Raimond-Bérenger III, Count of Barcelona, and Dolça, daughter of Gilbert I, Viscount of Gévaudan, and Gerberge d'Arles, Countess of Provence. He inherited his various counties upon his father's death in 1131. In 1137, he signed a marriage agreement with Ramire II, King of Aragon, who promised the hand of Petronilla (born the previous year) to the Count of Barcelona as soon as she reached the legal age of 14. The marriage took place in 1150. The signing of this agreement allowed him to unite his own domains with those of the Crown of Aragon and to bear the titles of Prince of Aragon and Count of Ribagorza. Taking advantage of the weakening of the Almoravids, he conquered several large cities in the south of his territory, including Almería, Tortosa and Lleida. His reign was also affected by the war he waged against his Christian neighbours to the north, the Counts of Toulouse and Provence, in what history calls "The Great Southern War". While crossing the Alps to meet Emperor Frederick I "Barbarossa" in Turin, he fell ill and died in early August 1162.

⁽³⁾Artal d'Artusella or Artal de Artusela was a knight from the minor nobility of Aragon, often referred to as "Mesnaderos" or "Infanzones". Virtually nothing is known about his origins or his life. The archives only mention him in connection with the conflict with the Knights Templar after he took their domain of Algars in 1216.
