Castilian Empire

The Castilian Empire refers to the vast territories ruled by the Kingdom of Castile, one of the most significant kingdoms of medieval Spain. Emerging in the 11th century, it played a crucial role in the Reconquista, the effort to reclaim Iberian land from Muslim rule. By the late 15th century, the union of Castile and Aragon under Ferdinand and Isabella led to the establishment of a unified Spanish state. The empire expanded overseas with discoveries in the Americas, establishing Spain as a dominant world power during the Age of Exploration, impacting global trade and culture significantly.
