  In 1519 Spanish explorer Alonso Álvarez de Pineda became the first recorded European to reach the Mississippi River, followed by Hernando de Soto who reached the river on May 8, 1541, and called it Río del Espíritu Santo ("River of the Holy Spirit"), in the area of what is now Mississippi. In Spanish, the river is called Río Mississippi.
  
  French explorers Louis Jolliet and Jacques Marquette began exploring the Mississippi in the 17th century. Marquette traveled with a Sioux Indian who named it Ne Tongo ("Big river" in Sioux language) in 1673. Marquette proposed calling it the River of the Immaculate Conception.
  
  When Louis Jolliet explored the Mississippi Valley in the 17th century, natives guided him to a quicker way to return to French Canada via the Illinois River. When he found the Chicago Portage, he remarked that a canal of "only half a league " (less than 2 miles or 3 kilometers) would join the Mississippi and the Great Lakes. In 1848, the continental divide separating the waters of the Great Lakes and the Mississippi Valley was breached by the Illinois and Michigan canal via the Chicago River. This both accelerated the development, and forever changed the ecology of the Mississippi Valley and the Great Lakes.
  
  In 1682, René-Robert Cavelier, Sieur de La Salle and Henri de Tonti claimed the entire Mississippi River valley for France, calling the river Colbert River after Jean-Baptiste Colbert and the region La Louisiane, for King Louis XIV. On March 2, 1699, Pierre Le Moyne d'Iberville rediscovered the mouth of the Mississippi, following the death of La Salle. The French built the small fort of La Balise there to control passage.
  
  In 1718, about 100 miles (160 km) upriver, New Orleans was established along the river crescent by Jean-Baptiste Le Moyne, Sieur de Bienville, with construction patterned after the 1711 resettlement on Mobile Bay of Mobile, the capital of French Louisiana at the time.
  
  In 1727, Étienne Perier begins work, using enslaved African laborers, on the first levees on the Mississippi River.
