Mardi Gras got going in New Orleans soon after the city’s founding in 1718. The Spanish, who ruled the Big Easy from 1762 to 1800, apparently cracked down on certain Mardi Gras rituals (though documentation from that period is scarce). U.S. authorities did much the same after taking control in 1803, banning both masked balls and public disguises. Nonetheless, they eventually accepted the festival’s existence. The first recorded Mardi Gras street parade in New Orleans took place in 1837, by which time the city had transformed from a small backwater into a major metropolis. Twenty years later, six men organized a secret society called the Mistick Krewe of Comus. By holding a parade with the theme of “The Demon Actors in Milton’s Paradise Lost,” along with a lavish grand ball, Comus reversed the declining popularity of Mardi Gras and helped establish New Orleans as its clear epicenter in the United States. This year, more than 1 million visitors are expected to attend.
