De Soto Discovering the Mississippi River.
Hernando de Soto ( c. 1500 – 21 May 1542) was 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.
