Each year, millions of tourists flock to major cities all over the world for a weekend-long celebration leading up to Fat Tuesday, or “Mardi Gras.” Donning masks, beads, and elaborate costumes, revelers have joined the festivities—and participated in the unique traditions of each country—for over 500 years. From Venice to Rio de Janeiro and, of course, New Orleans, The Daily Beast takes a look back at the history of Mardi Gras around the globe. Laissez les bons temps rouler!

It is singlehandedly responsible for the vast majority of Brazil’s annual tourism, bringing over 2 million tourists to the city of Rio de Janeiro. The festival is known for its “samba schools,” where groups of Carnival attendees from the same neighborhoods work together on floats, costumes, and dance routines to compete in Sambradrome, the climax of the festival.

The celebration begins in January and lasts until Fat Tuesday, which typically occurs in late February or early March. Just like celebrations throughout the rest of the world, the Haitian “karnaval” includes wild costumes, elaborate floats, and plenty of music and dancing. Harvey Meston/Getty Images The U.S. celebrations date back to 1699 when French-Canadian explorer Jean Baptiste Le Moyne Sieur de Bienville was sent to claim French territory in what is now Louisiana. Realizing it was the eve of the holiday, Bienville named the spot 60 miles south of what is now New Orleans “Pointe du Mardi Gras.” While the local traditions began in Mobile, Alabama, three years later—krewes were created and parades were organized—the major celebrations of Carnival today happen in New Orleans. Along with the elaborate floats, traditions also include masks, formal balls, and some pretty raunchy bead exchanges.

Particularly known for the elaborate masks attendees wear, the festival’s biggest event is the contest for la maschera più bella, or “the most beautiful mask,” which includes a judging panel of international costume and fashion designers.
