Overview 

The first Mardi Gras in America took place on Mar. 3, 1699, when French explorers landed in present day New Orleans, LA. They had a celebration and called their landing spot Point du Mardi Gras. Decades later, New Orleans still has celebrations of street parties, masked balls, and lavish dinners. When the Spanish took over New Orleans, they banned these rituals. This ban remained in place until 1812. In 1827, a group of students dressed in colorful costumes danced through the streets. Ten years later, the first Mardi Gras parade took place.

Origin  

Mardi Gras dates back to the Pagan spring and fertility rites. This includes the Roman traditions of Saturnalia and Lupercalia. When Christianity came to Rome the leaders decided to incorporate these local traditions into a new faith. This resulted in Mardi Gras becoming a prelude to Lent. It is also known as Carnival, Carnaval, or Fat Tuesday and is celebrated in many countries all around the globe. In some cultures it is a week-long celebration. 

Modern Practice

Long since Mardi Gras has been seen as a pagan spring rite, it is now a festival of colors and enjoying time with friends and family. Some current customs are throwing beads and trinkets, wearing masks, decorating floats, and eating King Cake.
