The history of Mardi Gras (Fat Tuesday)

Mardi Gras (French for "Fat Tuesday") is the last day of Carnival, the season of feasting before the 40 days of Lenten fasting. The tradition reaches back to medieval Europe, where households used up rich foods like eggs, milk and fat before the fast. French settlers brought it to New Orleans in 1699, and the city's parades date to the early 19th century. The British and Irish version is Shrove Tuesday, when pancakes use up the household's eggs and butter.

Also known as: Fat Tuesday, Shrove Tuesday, Pancake Day
