Cosa Nostra
Heroin trafficking between these two groups might have been discussed, but there certainly was not a general agreement on the heroin trade between "the" Sicilian Mafia and "the" American Cosa Nostra. The important result of 1957 Palermo gatherings was that the Sicilian Mafia composed its first Sicilian Mafia Commission and appointed "Little Bird" Greco as its first "primus inter pares".
