<P> Mardi Gras in the United States is not observed nationally across the country, however a number of cities and regions in the U.S. have notable Carnival celebrations . Most trace their Mardi Gras celebrations to French, Spanish, and other colonial influences on the settlements over their history . The earliest Carnival celebration in North America occurred at a place on the west bank of the Mississippi river about 60 miles (96.6 kilometers) downriver from where New Orleans is today; this Mardi Gras on the 3rd of March 1699 and in honor of this holiday, Pierre Le Moyne, Sieur d'Iberville, a 38 - year - old French Canadian, named the spot Point du Mardi Gras (French: "Mardi Gras Point") near Fort Jackson . The earliest organized Carnival celebrations occurred in Mobile, Biloxi, New Orleans, and Pensacola, which have each developed separate traditions . In addition, modern activities generally vary from city to city across the U.S. </P> <P> Mardi Gras arrived in North America as a sedate French Catholic tradition with the Le Moyne brothers, Pierre Le Moyne d'Iberville and Jean - Baptiste Le Moyne de Bienville, in the late 17th century, when King Louis XIV sent the pair to defend France's claim on the territory of Louisiane, which included what are now the U.S. states of Alabama, Mississippi, and Louisiana . </P> <P> The expedition, led by Iberville, entered the mouth of the Mississippi River on the evening of March 2, 1699, Lundi Gras, not yet knowing it was the river explored and claimed for France by René - Robert Cavelier, Sieur de La Salle in 1683 . The party proceeded upstream to a place on the west bank about 60 miles downriver from where New Orleans is today, where a small tributary emptied into the great river, and made camp in what is now Plaquemines Parish, Louisiana . This was on March 3, 1699, Mardi Gras day, so in honor of this holiday, Iberville named the spot Point du Mardi Gras (French: "Mardi Gras Point") and called the small tributary Bayou Mardi Gras . Bienville went on to found Mobile, Alabama in 1702 as the first capital of French Louisiana . In 1703 French settlers in that city began to celebrate the Mardi Gras tradition . By 1720, Biloxi was made capital of Louisiana . While it had French settlers, Mardi Gras and other customs were celebrated with more fanfare given its new status . In 1723, the capital of French Louisiana was moved to New Orleans, founded in 1718 . With the growth of New Orleans as a city and the creolization of different cultures, the varied celebration of Mardi Gras became the event most strongly associated with the city . In more recent times, several U.S. cities without a French Catholic heritage have instituted the celebration of Mardi Gras, which sometimes emerged as grassroots movements to help accompany single people to celebrate something in late Winter which is often dominated by the commercialized and couple - centric Valentine's Day, and as a result it has been co-opted as the single people's late Winter holiday . </P> <P> Mardi Gras is an official state holiday in Mobile and Baldwin counties . Other counties in the state grant employees a day of personal leave in lieu of Mardi Gras . </P>
