La Cosa Nostra is an Italian-American criminal society that dominates organized crime in the United States. The Italian-American Mafia has its roots in the Sicilian mob, but has been a separate organization in the United States for years. Many of the founding members of the American mafia emigrated from Italy in the beginning of the 20th century.
