Spanish conquistador Hernando de Soto and his forces enter Tula territory in present-day western Arkansas, encountering fierce resistance.

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.

The Tula were a Native American group that lived in what is now western Arkansas. The Tula are known to history only from the chronicles of Spanish conquistador Hernando de Soto's exploits in the interior of North America.
