Ferdinand of Aragon Biography

Ferdinand of Aragon and his wife, Isabella of Castille, underwrote the voyages of Christopher Columbus and so established Spain as a powerful force in the New World. The marriage of Ferdinand and Isabella in 1469 was politically arranged in a successful effort to unite their two kingdoms; under their rule Spain emerged as a unified and newly powerful country. Ferdinand and Isabella moved to establish Roman Catholicism as Spain's dominant religion, expelling Jews and Muslims and creating the infamous Spanish Inquisition. (Their efforts earned them the nickname Les Rois Catholiques, or the Catholic Monarchs.) Ferdinand oversaw multiple wars, most famously with the Moors of Grenada and with France in the so-called Italian Wars. Ferdinand outlived Isabella and upon his death in 1516 power passed to his grandson, Charles, who later became the Holy Roman Emperor Charles V.
