Years ago, the followers of the Catholic religion in Italy started the tradition of holding a wild costume festival right before the first day of Lent.
Since Catholics are prohibited from eating meat during Lent, they called their festival, carnevale — which means "to put away the meat." These carnivals in Italy became famous and spread to France, Spain, and other Catholic countries in Europe. As the French, Spanish, and Portuguese settled in the Americas and other parts of the world, their tradition of celebrating carnival and Mardi Gras expanded.
