A Brief History of Mardi Gras
Howard Tilton Memorial Library / Tulane University / AP
Origins
Literally meaning "Fat Tuesday," Mardi Gras is the culmination of a weeks-long Carnival season that ends on Ash Wednesday. While impromptu foot and horseback parades had been a regular New Orleans occurrence for decades, it was in 1857 that the first "krewe" private groups with semi-mythological namesakes that organize thematic parades was established. This 1879 picture details a parade by Rex, an all-male krewe whose leader is known as the "King of Carnival." The Krewe of Rex established the official Mardi Gras colors of green, gold, and purple.
