The 2nd Congress counted with the presence of Edison de Souza Carneiro (organizer), Martiniano do Bonfim, Camargo Guarnieri and Jorge Amado. Arthur Ramos and Melville Herskovits didn't participate in person.
Carneiro had good intentions when he wrote to Arthur Ramos:
"Club Itapagipe will lend us the tennis court for capoeira games. [..] Lets establish the Union of Capoeiras of Bahia, with the best capoeiras of the land. Maybe we do the same - and you know how this is difficult - with the saints-fathers."*
However these unions were never founded.
