El imperio hispano que dominó el Mediterráneo/Corona de Aragón 1137-1479

The Crown of Aragon,[note 2] also known by other alternative names, encompassed all the territories that, through conquests and marriages, were under the jurisdiction of the King of Aragon and Count of Barcelona between 1137 and 1707–1716.[1][12][13][2] In August 1137, Ramiro II the Monk, King of Aragon, negotiated a marriage agreement with Ramon Berenguer IV, Count of Barcelona, ​​for the latter's future marriage to his newborn daughter, Petronila.[note 3] In this agreement, Ramon Berenguer received the Kingdom of Aragon, henceforth holding the title of Princeps of Aragon. In 1162, Alfonso II of Aragon, the son of Petronila and Ramon Berenguer, inherited the combined patrimony, becoming the first sovereign to hold the titles of King of Aragon and Count of Barcelona. Later, through the conquest of new territories and marriages, this dynastic union under a single crown expanded its territories to include other domains: primarily the kingdoms of Majorca, Valencia, Sicily, Corsica, Sardinia, and Naples, and the duchies of Athens (from 1311 to 1388) and Neopatria (between 1319 and 1393). With the marriage of the Catholic Monarchs in 1469, the process of convergence with the Crown of Castile began, forming the basis of what would later become the Hispanic Monarchy, although the different kingdoms retained their legal systems and characteristics. With the Nueva Planta Decrees, promulgated between 1705 and 1716, Philip V finally eliminated most of these privileges and fueros (charters of rights), assimilating the institutional system of the Crown of Aragon to that of Castile. Some historians refer to the Aragonese monarchs by their aliases rather than their regnal number, as some of them had different numbering depending on the territory being referred to. For example, Peter the Catholic instead of Peter II of Aragon.
