And don't y'all forget it!
While not observed nationally throughout the United States, a number of cities and regions in the country have notable celebrations. Mardi Gras arrived in North America as a sedate French Catholic tradition with the Le Moyne brothers,<13> 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.<13>
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. 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.enlou.
Bienville went on to found the settlement of Mobile, Alabama in 1702 as the first capital of French Louisiana,<14> and in 1703 the Mardi Gras tradition began with celebrations by the French settlers in that city.http://en.wikipedia.org/wiki/Mardi_Gras#United_States
