Who dated James I of Aragon?

James I the Conqueror (Catalan: Jaume Icode: cat promoted to code: ca or Jaume el Conqueridorcode: cat promoted to code: ca ; Aragonese: Chaime I o Conqueridorcode: arg promoted to code: an ; 2 February 1208 – 27 July 1276) was King of Aragon, Count of Barcelona, and Lord of Montpellier from 1213 to 1276; King of Majorca from 1231 to 1276; and King of Valencia from 1238 to 1276. His long reign of 62 years is not only the longest of any Iberian monarch, but one of the longest monarchical reigns in history, ahead of Hirohito but remaining behind Queen Elizabeth II, Queen Victoria, Ferdinand I of the Two Sicilies, Bhumibol Adulyadej and King Louis XIV.

King James I saw the expansion of the Crown of Aragon in three directions: Languedoc to the north, the Balearic Islands to the southeast, and Valencia to the south. By a treaty with Louis IX of France, he achieved the renunciation of any possible claim of French suzerainty over the County of Barcelona and the other Catalan counties, while he renounced northward expansion and taking back the once Catalan territories in Occitania and vassal counties loyal to the County of Barcelona, lands that were lost by his father Peter II of Aragon in the Battle of Muret during the Albigensian Crusade and annexed by the Kingdom of France, and then decided to turn south. His great part in the Reconquista was similar in Mediterranean Spain to that of his contemporary Ferdinand III of Castile in Andalusia. One of the main reasons for this formal renunciation of most of the once Catalan territories in Languedoc and Occitania, and any expansion into them, is that he was raised by the Knights Templar Crusaders, who had defeated his father, who was fighting for the Pope alongside the French. It was thus effectively forbidden for him to try to maintain the traditional influence of the Count of Barcelona that previously existed in Occitania and Languedoc.

As a legislator and organiser, he occupies a high place among the European kings. King James I compiled the Llibre del Consolat de Mar, which governed maritime trade and helped establish Aragonese supremacy in the western Mediterranean. He was an important figure in the development of the Catalan language, sponsoring Catalan literature and writing a quasi-autobiographical chronicle of his reign: the Llibre dels fets.

Guillema de Cabrera (?-1277) fue concubina de Jaime I de Aragón y esposa de Bernat de Cabrera (llamado también Berenguer) -muerto el 1248-, castellano de los castillos de Cabrera y señor de Voltregà. Considerada hija del conde Hugo IV de Ampurias.​

Fruto de su relación con el rey en 1250 recibió el Castillo de Eramprunyá, y dos años después le fue otorgado el contrato de concubinaje y el castillo y la villa de Tarrasa, propiedades que después en el 1274 permutó con el rey por el castillo y la villa de Gurb, a la vez que le era confirmada la consigna sobre el castillo de Tarrasa que había hecho a favor de su hijo Arnau de Cabrera y de la mujer de este, Sibila de Saga -la cual fue la última concubina de Jaime I-.​
