Ferdinand De Soto, The Discoverer of the Mississippi: American Pioneers and Patriots

This is a biography of a man named Hernando de Soto (often known as Ferdinand de Soto in earlier records), a Spanish explorer and conquistador who was involved in expeditions in Nicaragua and the Yucatan Peninsula. He played an important role in Francisco Pizarro's conquest of the Inca Empire in Peru, but is best known for leading the first European expedition deep into the territory of the modern-day United States (through Florida, Georgia, Alabama, Mississippi, and most likely Arkansas). He is the first European documented as having crossed the Mississippi River.
