Carnival is a big party celebrated before Lent in Catholic traditions. It originated in Italy in 1268 as a way for Catholics to enjoy meat and festivities before the fasting and prayer of the 40 days of Lent. The tradition spread to other Catholic countries in Europe and then around the world. Some of the most famous carnivals include Mardi Gras in New Orleans, Rio de Janeiro's Samba Parades, and Cádiz's celebrations featuring comedic music groups that travel through the streets.
