Mardi Gras refers to events of the Carnival celebrations that begin after Epiphany and end on the day before Ash Wednesday, known as Fat Tuesday. It originated from the French Catholic tradition of eating richer foods before the fasting season of Lent. Popular Mardi Gras traditions include wearing masks and costumes, dancing, sports, and parades. While not celebrated nationally in the US, historically French cities like New Orleans and Mobile have notable Mardi Gras celebrations that have become strongly associated with their cultures.
