The Carnival of Brazil (Portuguese: Carnaval do Brasil, IPA: [kaʁnaˈvaw]) is an annual Brazilian festival held between the Friday afternoon before Ash Wednesday and Ash Wednesday at noon, which marks the beginning of Lent, the forty-day period before Easter. During Lent, Roman Catholics and some other Christians traditionally abstained from the consumption of meat and poultry, hence the term "carnival", from carnelevare, "to remove (literally, "raise") meat." Rhythm, participation, and costumes vary from one region of Brazil to another. In the southeastern cities of Rio de Janeiro, São Paulo, and Vitória, huge organized parades are led by samba schools. Those official parades are meant to be watched by the public, while minor parades ("blocos") allowing public participation can be found in other cities, like Belo Horizonte, also in the southeastern region.
The northeastern cities of Recife, Olinda, Salvador, and Porto Seguro have organized groups parading through streets, and public interacts directly with them. This carnival is also influenced by African-Brazilian culture. It is a six-day party where crowds follow the trios elétricos through the city streets, dancing and singing. Also in northeast, Olinda carnival features unique characteristics, heavily influenced by local folklore and cultural manifestations, such as Frevo and Maracatu. The typical genres of music of Brazilian carnival are, in the Southeast Region in general, mostly cities of Rio de Janeiro and São Paulo: the samba-enredo, the samba de bloco, the samba de embalo and the marchinha; and in the Northeast Region including Pernambuco (mostly cities of Olinda and Recife): frevo and maracatu, and Bahia (mostly the city of Salvador): samba-reggae, pagode (also a type of Samba) and the main genre axé music; all of which are linked back to Afro-Brazilian culture.
Carnival is the most famous holiday in Brazil and has become an event of huge proportions. Except for industrial production, retail establishments such as malls, and carnival-related businesses, the country unifies completely for almost a week and festivities are intense, day and night, mainly in coastal cities. Rio de Janeiro's carnival alone drew 4.9 million people in 2011, with 400,000 being foreigners. This cultural manifestation is generally an extension of Afro-Brazilian culture, though could also be historically traced to the Portuguese Age of Discoveries when their caravels passed regularly through Madeira, a territory which already celebrated emphatically its carnival season, and where they were loaded with goods but also people and their ludic and cultural expressions.
