who established the first european base in mississippi in 1699
Mississippi In April 1699, French colonists established the first European settlement at Fort Maurepas (also known as Old Biloxi), built in the vicinity of present-day Ocean Springs on the Gulf Coast. It was settled by Pierre Le Moyne d'Iberville. In 1716, the French founded Natchez on the Mississippi River (as Fort Rosalie); it became the dominant town and trading post of the area. The French called the greater territory "New France"; the Spanish continued to claim part of the Gulf coast area (east of Mobile Bay) of present-day southern Alabama, in addition to the entire area of present-day Florida.
French colonization of Texas Spain learned of La Salle's mission in 1686. Concerned that the French colony could threaten Spain's control over the Viceroyalty of New Spain and the unsettled southeastern region of North America, the Crown funded multiple expeditions to locate and eliminate the settlement. The unsuccessful expeditions helped Spain to better understand the geography of the Gulf Coast region. When the Spanish finally discovered the remains of the French colony at the fort in 1689, they buried the cannons and burned the buildings. Years later, Spanish authorities built a presidio at the same location. When the presidio was abandoned, the site of the French settlement was lost to history.
