Cosa Nostra (Sicilian Mafia)

Cosa Nostra, also known as the Sicilian Mafia, is an organized crime group originating in Sicily. It operates through a hierarchical structure of bosses, underbosses, and members who enforce codes of loyalty and silence, known as "omertà." They engage in illegal activities such as extortion, loan sharking, drug trafficking, and violence to maintain power and influence. While initially rooted in local crime, Cosa Nostra has historically expanded its reach internationally. Its operations rely heavily on secrecy, corruption, and intimidation, making it a significant obstacle to law enforcement efforts in combating organized crime.
