The early history of the Mafia parallels that of the Camorra in Naples in the late 1800's and is identified as a secret society composed of peasants with an Italian ancestry. In time, the Mafia grew and expanded to the United States, where it grew during the prohibition era. The Mafia recognized the potential lucrativeness of drug trafficking and established ties with traffickers in the Golden Triangle who supplied heroin to Palermo, Sicily, for transportation to the United States.
