Hernando de Soto was one of the first European explorers of the Mississippi River, but it was Robert Cavelier, Sieur de La Salle, who claimed the river for France in the late 17th century. La Salle established trade relations with Native Americans and founded Fort Rosalie, which facilitated further French settlement. His explorations laid the groundwork for establishing New Orleans and expanding French territories in North America.
