The French celebrated this holiday since the Middle Ages, the tradition took hold in New Orleans while it was ruled by France. However, when the United States bought New Orleans from Napoleon, the tradition was banned.

In 1823, a large Creole population convinced the United States government to recognized the holiday and reinstate Fat Tuesday in New Orleans. And the first document parade began in 1837 when masked party goers marched through the streets. A group of men from Mobile, Ala. formed an organization called Comus and reportedly  coined the word krewe, which became the groups that hold the Mardi Gras parades through the city streets.

Today, nearly 50 krewes hold parades and balls in various cities throughout the United States. Since the 1850s, parades have been held annually, except during World War I and World War II, when events were forced to be placed on hold for a few years.

Other cities, such as St. Louis, San Diego, Baton Rouge and Detroit also hold Fat Tuesday festivities.
