The Coosa chiefdom was a powerful Native American paramount chiefdom in what are now Gordon and Murray counties in Georgia, in the United States. It was inhabited from about 1400 until about 1600, and dominated several smaller chiefdoms. The total population of Coosa's area of influence, reaching into present-day Tennessee and Alabama, has been estimated at 50,000.

Hernando de Soto 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. He is the first European documented as having crossed the Mississippi River.
