Two achievements made by the Los Reyes Católicos was the unification of Spain and the retaking of Granada from Moorish occupation. The Los Reyes Católicos, meaning the Catholic Monarchs in English, is a title shared between Ferdinand II of Aragon and Isabella I of Castile.
The two Spanish monarchs married in 1469, uniting the kingdoms of Aragon and Castile under one marriage, if not one unified kingdom. The Catholic Monarchs are also credited for funding Christopher Columbus' journey that eventually led to the discovery of the New World in 1492. They were granted the appellation "Catholic" or "Católicos" by Pope Alexander VI in 1494.
