LigaSP
The Liga Independente das Escolas de Samba de São Paulo - Independent League of the Samba Schools of São Paulo - or LigaSP is an entity that administrates the Special and Access Groups of the Carnaval of São Paulo.
In 1986 directors of the principal samba schools of São Paulo and a group of samba composers and dancers gathered in an assembly decided to create an association that would administrate the Paulista carnival.
Nowadays the LigaSP manages the parades, repassing the lucres to the samba schools of the Special and Access Groups, creating a group of sporting samba schhols.
