The holiday of Mardi Gras is celebrated in southern Louisiana, including the city of New Orleans. Celebrations happen for about two weeks, culminating on Mardi Gras (French for "Fat Tuesday"), a celebratory name for Shrove Tuesday, the day before Ash Wednesday, which is the start of Lent in the Western Christian tradition. The overall season is known as Carnival and begins on 12th Night, January 6th, and extends until midnight before Ash Wednesday. Parties known as Club or Krewe balls start soon after, many of which are private, with their Kings and Queens coming from wealthy old families and their courts consisting of the season's debutantes. Most of the high society Krewes do not stage parades. As Fat Tuesday approaches, Mardi Gras parades start in earnest. Usually there is one major parade scheduled each day, while many days have several large parades. The largest and most elaborate parades take place the last five days of the Mardi Gras season. In the final week, many events occur throughout New Orleans and surrounding communities, including parades and balls (some of them masquerade balls).

The parades in New Orleans are organized by social clubs known as krewes; most follow the same parade schedule and route each year. The earliest-established krewes were the Mistick Krewe of Comus, the earliest, Rex, the Knights of Momus and the Krewe of Proteus. Several modern "super krewes" are well known for holding large parades and events (often featuring celebrity guests), such as the Krewe of Endymion, the Krewe of Bacchus, as well as the Zulu Social Aid & Pleasure Club—a predominantly African American krewe. Float riders traditionally toss throws into the crowds. The most common throws are strings of colorful plastic beads, doubloons, decorated plastic "throw cups", and small inexpensive toys. Major krewes follow the same parade schedule and route each year.

While many tourists center their Carnival season activities on Bourbon Street, major parades originate in the Uptown and Mid-City districts and follow a route along St. Charles Avenue and Canal Street, on the upriver side of the Spanish Quarter. Walking parades - most notably the Krewe du Vieux and 'tit Rex - also take place downtown in the Faubourg Marigny and Spanish Quarter in the weekends preceding Mardi Gras Day. Mardi Gras Day traditionally concludes with the "Meeting of the Courts" between Rex and Comus.

History

Early history The first record of Mardi Gras being celebrated in Louisiana was at the mouth of the Mississippi River in what is now lower Plaquemines Parish, Louisiana, on March 2, 1699. Iberville, Bienville, and their men celebrated it as part of an observance of Catholic practice. The date of the first celebration of the festivities in New Orleans is unknown. A 1730 account by Marc-Antoine Caillot celebrating with music and dance, masking and costuming (including cross-dressing).Excerpt A Company Man - The Book An account from 1743 that the custom of Carnival balls was already established. Processions and wearing of masks in the streets on Mardi Gras took place. They were sometimes prohibited by law, and were quickly renewed whenever such restrictions were lifted or enforcement waned.

In 1833, Bernard Xavier de Marigny de Mandeville, a rich plantation owner of French descent raised money to fund an official Mardi Gras celebration. James R. Creecy in his book Scenes in the South, and Other Miscellaneous Pieces describes New Orleans Mardi Gras in 1835:

Shrove Tuesday is a day to be remembered by strangers in New Orleans, for that is the day for fun, frolic, and comic masquerading. All of the mischief of the city is alive and wide awake in active operation. Men and boys, women and girls, bond and free, white and black, yellow and brown, exert themselves to invent and appear in grotesque, quizzical, diabolic, horrible, strange masks, and disguises. Human bodies are seen with heads of beasts and birds, beasts and birds with human heads; demi-beasts, demi-fishes, snakes' heads and bodies with arms of apes; man-bats from the moon; mermaids; satyrs, beggars, monks, and robbers parade and march on foot, on horseback, in wagons, carts, coaches, cars, &c., in rich confusion, up and down the streets, wildly shouting, singing, laughing, drumming, fiddling, fifeing, and all throwing flour broadcast as they wend their reckless way.

In 1856, 21 businessmen gathered at a club room in the French Quarter to organize a secret society to observe Mardi Gras with a formal parade. They founded New Orleans' first and oldest krewe, the Mistick Krewe of Comus. According to one historian, "Comus was aggressively English in its celebration of what New Orleans had always considered a French festival. It is hard to think of a clearer assertion than this parade that the lead in the holiday had passed from French-speakers to Anglo-Americans. ... To a certain extent, Americans 'Americanized' New Orleans and its Creoles. To a certain extent, New Orleans 'creolized' the Americans. Thus the wonder of Anglo-Americans boasting of how their business prowess helped them construct a more elaborate version than was traditional. The lead in organized Carnival passed from Creole to American just as political and economic power did over the course of the nineteenth century. The spectacle of Creole-American Carnival, with Americans using Carnival forms to compete with Creoles in the ballrooms and on the streets, represents the creation of a New Orleans culture neither entirely Creole nor entirely American."All on a Mardi Gras Day: Episodes in the History of New Orleans Carnival by Reid Mitchell. Harvard University Press:1995. pg 25, 26

In 1875, Louisiana declared Mardi Gras a legal state holiday. War, economic, political, and weather conditions sometimes led to cancellation of some or all major parades, especially during the American Civil War, World War I and World War II, but the city has always celebrated Carnival.Sparks, R.

The 1898, Rex parade, with the theme of "Harvest Queens", was filmed by the American Mutoscope Co. The rumored but long-lost recording was rediscovered in 2022. The two-minute film records 6 parade floats, including one transporting a live ox. In December 2022, the film was deemed "culturally, historically, or aesthetically significant" by the National Film Registry by the Library of Congress.

20th and 21st centuries

In 1979, the New Orleans police department went on strike. The official parades were canceled or moved to surrounding communities, such as Jefferson Parish, Louisiana. Significantly fewer tourists than usual came to the city. Masking, costuming, and celebrations continued anyway, with National Guard troops maintaining order. Guardsmen prevented crimes against persons or property but made no attempt to enforce laws regulating morality or drug use; for these reasons, some in the French Quarter bohemian community recall 1979 as the city's best Mardi Gras ever.

In 1991, the New Orleans City Council passed an ordinance that required social organizations, including Mardi Gras Krewes, to certify publicly that they did not discriminate on the basis of race, religion, gender or sexual orientation, to obtain parade permits and other public licenses. Shortly after the law was passed, the city demanded that these krewes provide them with membership lists, contrary to the long-standing traditions of secrecy and the distinctly private nature of these groups. In protest—and because the city claimed the parade gave it jurisdiction to demand otherwise-private membership lists—the 19th-century krewes Comus and Momus stopped parading. Proteus did parade in the 1992 Carnival season but also suspended its parade for a time, returning to the parade schedule in 2000.

Several organizations brought suit against the city, challenging the law as unconstitutional. Two federal courts later declared that the ordinance was an unconstitutional infringement on First Amendment rights of free association, and an unwarranted intrusion on the privacy of the groups subject to the ordinance.The decision of the Fifth Circuit Court of Appeals appears at volume 42, page 1483 of the Federal Reporter (3rd Series), or 42 F.3d 1483 (5th Cir. 1995). The US Supreme Court refused to hear the city's appeal from this decision.

Today, New Orleans krewes operate under a business structure; membership is open to anyone who pays dues, and any member can have a place on a parade float.

Effects of Hurricane Katrina The devastation caused by Hurricane Katrina on August 29, 2005, caused a few people to question the future of the city's Mardi Gras celebrations. Mayor Nagin, who was up for reelection in early 2006, tried to play this sentiment for electoral advantage. However, the economics of Carnival were, and are, too important to the city's revival.

The city government, essentially bankrupt after Hurricane Katrina, pushed for a scaled back celebration to limit strains on city services. However, many krewes insisted that they wanted to and would be ready to parade, so negotiations between krewe leaders and city officials resulted in a compromise schedule. It was scaled back but less severely than originally suggested.

The 2006 New Orleans Carnival schedule included the Krewe du Vieux on its traditional route through Marigny and the French Quarter on February 11, the Saturday two weekends before Mardi Gras. There were several parades on Saturday, February 18, and Sunday the 19th a week before Mardi Gras. Parades followed daily from Thursday night through Mardi Gras. Other than Krewe du Vieux and two Westbank parades going through Algiers, all New Orleans parades were restricted to the Saint Charles Avenue Uptown to Canal Street route, a section of the city which escaped significant flooding. Some krewes unsuccessfully pushed to parade on their traditional Mid-City route, despite the severe flood damage suffered by that neighborhood.

The city restricted how long parades could be on the street and how late at night they could end. National Guard troops assisted with crowd control for the first time since 1979. Louisiana State troopers also assisted, as they have many times in the past. Many floats had been partially submerged in floodwaters for weeks. While some krewes repaired and removed all traces of these effects, others incorporated flood lines and other damage into the designs of the floats.

Most of the locals who worked on the floats and rode on them were significantly affected by the storm's aftermath. Many had lost most or all of their possessions, but enthusiasm for Carnival was even more intense as an affirmation of life. The themes of many costumes and floats had more barbed satire than usual, with commentary on the trials and tribulations of living in the devastated city. References included MREs, Katrina refrigerators and FEMA trailers, along with much mocking of the Federal Emergency Management Agency (FEMA) and local and national politicians.

By the 2009 season, the Endymion parade had returned to the Mid-City route, and other Krewes expanding their parades Uptown.
