The term "Boston Mob" typically refers to organized crime groups that operated in Boston, Massachusetts, particularly during the mid-20th century. These groups were involved in various illegal activities, including gambling, drug trafficking, and extortion. The most notorious of these was the Winter Hill Gang, which was led by figures like James "Whitey" Bulger. The Boston Mob was known for its connections to both local and national crime syndicates, including the Italian-American Mafia. Law enforcement efforts to combat organized crime in Boston intensified in the 1970s and 1980s, leading to numerous arrests and convictions. The legacy of the Boston Mob continues to influence popular culture and crime narratives today.
