Originally, Samba was the collective name for several dance styles, introduced by slaves from the Congo, western Sudan and Angola into their new homeland, Brazil, in the 19th century.
Being one of the most significant expressions of Brazilian folk culture, Samba has turned into a symbol of national identity. The Samba de Roda from Bahia, declared heritage of humanity by UNESCO in 2005, formed the basis for the development of the Samba Carioca (from Rio de Janeiro).
