The first escolas de samba or samba school to be formed was Mangueira, in 1928. Soon theme songs, elaborate costumes, and floats became the main attraction of the Rio Carnival. Many other teams from different communities in the Rio neighborhood followed Mangueira’s footsteps and formed samba schools to take part in the Carnival. The samba parade soon became the most popular event in Rio with the organizers being forced to set a time limit for each team in 1971. The streets of Rio remained the main stage for the Carnival until 1984, Some of the best-known samba schools are Unidos da Tijuca, Beija Flor, Salgueiro, Mangueira, Mocidade and Grande Rio.
