The National Crime Syndicate was a coalition of organized crime groups in the United States that emerged in the 1930s. It was formed by various criminal organizations, including the Italian Mafia, Jewish mob, and other ethnic gangs, to collaborate on illegal activities such as drug trafficking, extortion, and gambling. This alliance allowed them to expand their influence and operations across the country. The Syndicate played a significant role in shaping organized crime in America, particularly during the Prohibition era. Key figures included notorious mobsters like Lucky Luciano and Meyer Lansky, who helped establish a more structured approach to crime. The National Crime Syndicate's impact is still studied in relation to modern organized crime.
