Summarize how Spain changed in a social, economic and political sense after the Reconquista in Spain?

The Reconquista, which concluded in 1492, had far-reaching implications for the culture, economy, and government of Spain.  Socially, the expulsion of Muslims and Jews from Spain created a unified and homogeneous population under a Catholic monarchy.  With the marriage of Ferdinand and Isabella, Spain experienced political stability that allowed it to reach new heights.  The unity that was felt after the Reconquista led to unbridled expansion by Spain, beginning with the voyages of Christopher Columbus to the New World.  Within a half of a century, Spain's colonial holdings in the Americas were expansive and prosperous.  The gold and silver acquired through the Spanish colonies enriched Spain to the point that they were the wealthiest nation in Europe.  This wealth was used to build a large fleet of warships known as the Spanish Armada.  This economic and military dominance became the envy of the Western world during the 16th Century.
