Cosa Nostra

Cosa Nostra is a powerful and secretive criminal organization that originated in Sicily, Italy, in the late 19th century. Known as the Sicilian Mafia, it is involved in various illegal activities, including drug trafficking, extortion, and money laundering. Cosa Nostra operates through a strict hierarchical structure and values loyalty and silence among its members, famously known as "omertà." It has historically exerted significant influence over local politics and economy through intimidation and corruption. Cosa Nostra's activities have drawn extensive law enforcement efforts, particularly in Italy and the United States, leading to numerous convictions and dismantling efforts.
