The Aragonese dynasty refers to the royal family that ruled the Kingdom of Aragon, a significant medieval kingdom in northeastern Spain. This dynasty played a crucial role in the political landscape of the Iberian Peninsula, especially during the 12th to 15th centuries. The Aragonese monarchs were known for their military conquests and alliances, which expanded their territory and influence. One of the most notable figures of the Aragonese dynasty was Ferdinand II of Aragon, who, along with his wife Isabella I of Castile, unified Spain through their marriage. Their reign marked the beginning of the Spanish Empire, leading to the exploration of the New World and the establishment of Spanish dominance in global affairs.
