How did Spain unify its country?

Answer 1

Spain unified primarily through the dynastic marriage of Ferdinand II of Aragon and Isabella I of Castile in 1469, which brought together two of the largest kingdoms on the Iberian Peninsula. Their subsequent efforts to consolidate power included the completion of the Reconquista in 1492, the establishment of a centralized monarchy, and the promotion of a common Spanish identity. The unification process continued through the integration of various regions and the imposition of a standardized language and culture. Over time, these efforts laid the foundation for modern Spain's territorial and political unity.
