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.
Spanish Florida Spanish Florida was established in 1513, when Juan Ponce de León claimed peninsular Florida for Spain during the first official European expedition to North America. This claim was enlarged as several explorers (most notably Pánfilo Narváez and Hernando de Soto) landed near Tampa Bay in the mid-1500s and wandered as far north as the Appalachian Mountains and as far west as Texas in largely unsuccessful searches for gold and other riches[clarification needed]. The presidio of St. Augustine was founded on Florida's Atlantic coast in 1565; a series of missions were established across the Florida panhandle, Georgia, and South Carolina during the 1600s; and Pensacola was founded on the western Florida panhandle in 1698, strengthening Spanish claims to that section of the territory.
