The marriage of King Ferdinand and Queen Isabella in 1469 primarily united Christian kingdoms to form the country of Spain. Their union brought together the kingdoms of Aragon and Castile, which laid the groundwork for the political unification of Spain. This also helped strengthen the Christian presence in the Iberian Peninsula and ultimately played a significant role in the completion of the Reconquista, culminating in the capture of Granada in 1492.
