The USA is an interesting place, it's history has influenced it's Carnivals that occur annually across it's states each year. The most famous of these is the Mardis Gras in New Orleans.
The Mardis Gras made its way over to North America via the French-Canadian explorer Pierre Le Moyne, Sieur d'Iberville in 1699, when he named his campsite Point du Mardi Gras . He later held a small gala at the campsite, located about 97 kilometers downriver from present-day New Orleans.
Starting in 1703, French soldiers and settlers enjoyed Mardi Gras festivities in the newly founded city of Mobile, which served as the capital of French Louisiana territory, until the capital was moved to New Orleans. More than 100 years later, the first recorded Mardi Gras street parade in New Orleans took place in 1837. After violent acts nearly shut down the celebrations, New Orleans businessmen formed the Mistick Krewe of Comus, a secret society that showcased a themed parade with elaborate floats and performers and a lavish post-parade gala in 1857.
This evolution of Krewes and parades over the past 150 years into part-cultural tradition and part-wild party is what shapes Mardi Gras celebrations across the U.S. and In other states there are various Carnivals, that have influences from other regions, such as the Carnival of San Francisco which has South American and Spanish influences or the Carnivals in Miami, Atlanta, and Hollywood or the Labor Day Carnival of New York and more.
Other similar festivals include the Canadian Carnivals in Toronto and Montreal, and the Junkanoo of South Carolina. We would recommend North American Carnivals for spectators and for those who want to participate in the Festival.
