Super Sunday and the Mardi Gras Indians :
Mardi Gras is full of secrets, and the Mardi Gras Indians are as much a part of that secrecy as any other carnival organization. Their parade dates, times and routes are never published in advance, although they do tend to gather in the same areas every year.
The Mardi Gras Indians are comprised, in large part, of the African-American communities of New Orleans's inner city. While these Indians have paraded for well over a century, their parade is perhaps the least recognized Mardi Gras tradition.
"Mardi Gras Indians--the parade most white people don't see. The ceremonial procession is loose, the parade is not scheduled for a particular time or route...that is up to the Big Chief." - Larry Bannock
Traditional Mardi Gras organizations form a "krewe." A krewe often names their parade after a particular Roman or Greek mythological hero or god. The ranking structure of a Mardi Gras Krewe is a parody of royalty: King, Queen, Dukes, Knights and Captains, or some variation of that theme. Many of the more established krewes allow membership by invitation only.
Few in the ghetto felt they could ever participate in the typical New Orleans parade. Historically, slavery and racism were at the root of this cultural separation. The black neighborhoods in New Orleans gradually developed their own style of celebrating Mardi Gras. Their krewes are named for imaginary Indian tribes according to the streets of their ward or gang. - Mardi Gras Indians History and Tradition
