James II agreed to become a vassal of Aragon by treaty.

In 1279, Spain witnessed a pivotal moment when James II, the King of Mallorca, agreed by treaty to become a vassal of Aragon. This treaty marked a crucial turning point in the political landscape of Spain, as it solidified Aragon's dominance over the region and initiated a period of close cooperation between the two kingdoms. As a vassal, James II pledged his loyalty and recognized the authority of the Aragonese kings, thus ensuring their control over Mallorca and effectively integrating it into the broader Aragonese realm. This agreement not only secured Aragon's influence in Spain but also established a stronger foundation for future unity and cooperation among the various kingdoms of the Iberian Peninsula. It laid the groundwork for the later unification of Spain under the Catholic Monarchs and set in motion the consolidation of power that would ultimately shape the country's history. #Spain #JamesII #Aragon #treaty #politicalunification
