During the 1500s, Spanish explorers, called conquistadors, plundered the native Indian civilizations of North and South America of their gold and silver and enslaved the inhabitants.
They were brave, hard, and ruthless men who were quick to use their swords, having honed their skills during years of fighting Muslims in Spain. The conquistadors put millions of Indians under Spanish rule.
Ships, heavily loaded with bars of gold and silver, sailed back to Spain, making it the richest nation on earth. The Spanish Empire would endure 300 years.
