La Cosa Nostra

La Cosa Nostra, often referred to as the Mafia, is a criminal organization that originated in Sicily, Italy, in the 19th century. It became prominent in the United States in the early 20th century, particularly in cities like New York. The group is known for its involvement in various illegal activities, including extortion, drug trafficking, and organized crime. La Cosa Nostra operates under a code of silence called "omertà," promoting loyalty among its members and discouraging cooperation with law enforcement. It has a hierarchical structure, with leaders known as "bosses" who oversee various operations and territories.
