Profession: King of Aragon
Why Famous: One of the so-called Catholic Monarchs, Ferdinand married Isabella I of Castile, and their marriage began the process of Spanish unification.
Together they sponsored the voyages of Christopher Columbus to the New World where he discovered the Americas, and later completed the centuries-long process of Reconquista, the recapture of Muslim-held territories on the Iberian peninsula.
He also formed the Spanish Inquisition with his wife, initially to find and punish heretics among the Muslims and Jews who had converted to Catholicism and to maintain orthodox Catholicism within their empires.
He was also King of Naples, King of Castile through his wife's reign and King of Navarre by conquest.
