The first European to explore the Mississippi was Hernando De Soto who crossed it on his final expedition in 1541. The upper regions were explored by the 1673 travels of Jacques Marquette and Louis Joliet, and the entire Mississippi valley was claimed as La Louisiane following the 1682 voyage of La Salle (Rene-Robert Cavelier, Sieur de La Salle).
