Who is the Sicilian mafia?

The Sicilian Mafia, also known as Cosa Nostra, is a criminal organization that originated in Sicily, Italy, in the 19th century. It is involved in various illicit activities, including drug trafficking, extortion, and money laundering, and is known for its code of silence, or "omertà." The Mafia gained significant power and influence in Italy and abroad, particularly in the United States, where it established strong connections with organized crime networks. Over the years, law enforcement efforts have targeted the Mafia, leading to numerous arrests and prosecutions of its leaders and members.
