Mardi Gras is a traditional holiday celebrated in many of the southern states of the USA. The most  famous celebration takes place in New Orleans, Louisiana. The people there enjoy this celebration by going to parades where they catch "beads, doubloons, cups, and trinkets" that are all thrown from floats.
They have masquerade balls and dress up in costumes for these events. King Cakes are eaten during this holiday. Mardi Gras is known as the "biggest free show on earth."
Mardi Gras came to New Orleans through its French heritage in 1699. Early explorers celebrated this French Holiday on the banks of the Mississippi River. Throughout the years, Orleanians have added to the celebration by establishing krewes (organizations) which host parades and balls. Carnival quickly became an exciting holiday for both children and adults.
Mardi Gras means "Fat Tuesday" and of course is celebrated on that day of the week. The date can fall between February 3 and March 9 depending on the Lunar calendar, used by the Catholic Church to determine the date of Easter. Mardi Gras is always 47 days before Easter Sunday.
The official colors for Mardi Gras are purple, green, and gold. These colors where chosen in 1872 by the King of Carnival, Rex. He chose these colors to stand for the following:
Purple represents justice
green stands for faith
gold stands for power |
