New Orleans Social clubs play a very large part in the Mardi Gras celebration as hosts of many of the parades on or around Mardi Gras. The two main Mardi Gras parades, Zulu and Rex, are both social club parades. Zulu is a mostly African-American club and Rex is mostly Caucasian. Social clubs host Mardi Gras balls, starting in late January. At these social balls, the queen of the parade (usually a young woman between the ages of 18 and 21, not married and in high school or college) and the king (an older male member of the club) present themselves and their court of maids (young women aged 16 to 21), and different divisions of younger children with small roles in the ball and parade, such as a theme-beformal neighborhood Carnival club ball at local bar room.
