The early French in New Orleans celebrated Mardi Gras with masked balls and parties, until the Spanish government took over in the mid-1700s and banned the celebrations. The ban continued even after the U.S. government acquired the land but the celebrations resumed in 1827. The official colors of Mardi Gras, with their roots in Catholicism, were chosen 10 years later: purple, a symbol of justice; green, representing faith; and gold, to signify power.
Mardi Gras literally means "Fat Tuesday" in French. The name comes from the tradition of slaughtering and feasting upon a fattened calf on the last day of Carnival. The day is also known as Shrove Tuesday (from "to shrive," or hear confessions), Pancake Tuesday and fetter Dienstag. The custom of making pancakes comes from the need to use up fat, eggs and dairy before the fasting and abstinence of Lent begins.
