James I of Aragon
James I the Conqueror (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 Valencia from 1238 to 1276.
His long reign—the longest of any Iberian monarch—saw the expansion of the House of Aragon and House of Barcelona 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 wrested the County of Barcelona from nominal French suzerainty and integrated it into his crown.
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 the fact that he was raised by the Knights Templar crusaders, who had defeated his father fighting for the Pope alongside the French, so it was 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.
James 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".
