Sieur de La Salle, a French explorer, was the first European to travel the length of the Mississippi River. He was sent by King Louis XIV. He travelled south from Canada and sailed down the Mississippi River to the Gulf of Mexico.

Pierre Le Moyne D'Iberville is known for exploring the northern coast of the Gulf of Mexico. He rediscovered the mouth of the Mississippi River and established a temporary fort, Fort Maurepas, on Biloxi Bay later.
