The history of Mardi Gras can be tracked back thousands of years. When Christianity arrived in Rome, religious leaders decided to keep already popular traditions such as, celebrations of spring and fertility and the rowdy Roman festivals of Saturnalia and Lupercalia, in their new faith calendar. Which is why, excess and debauchery are often linked to this world famous holiday.

According to historians, those who were planning on attending the festivities would binge on foods and drinks in preparation for Lent, the season of the Christian Year where devotees focus on simple living, prayer, and fasting in order to grow closer to God. All of the sudden it makes sense that the holiday is also referred to as “Fat Tuesday,” correct?

Many connoisseurs believe that the first American Mardi Gras took place on March 3, 1966. However, in 1827, a group of students decided to dress up in colorful costumes and danced through the streets of New Orleans, a ritual they borrowed from the French. Ten years later, the first official Mardi Gras parade took place and the tradition continues to this day.

This year, Mardi Grass falls on Tuesday, February 9, and partygoers from all over the world are already heading to New Orleans, where you can catch the most popular parades, like Endymion, Bacchus, Zulu, Rex, and all of the festive celebrations the city has to offer.
