and talk of umirtà (omertà or code of silence) and "pizzu" (a codeword for extortion money). The play had great success throughout Italy. Soon after, the use of the term "mafia" began appearing in the Italian state's early reports on the group. The word was first documented in 1865 in a report by the prefect of Palermo Filippo Antonio Gualterio (it). The term mafia has become a generic term for any organized criminal network with similar structure, methods, and interests. But Giovanni Falcone, the anti-Mafia judge who was murdered by the Mafia in 1992, had objected to the conflation of the term "Mafia" with organized crime in general: According to Mafia turncoats (pentiti), the real name of the Mafia is "Cosa Nostra" ("Our Thing"). Italian-American mafioso Joseph Valachi testified before the Permanent Subcommittee on Investigations of the U.S. Senate Committee on Government Operations in 1963 (at what are known as the Valachi hearings). He revealed that American mafiosi referred to their organization by the term cosa nostra ("our thing" or "this thing of ours" or simply "our cause" / "our interest"). At the time, Cosa Nostra was understood as a proper name, fostered by the FBI and disseminated by the media. The FBI added the article la to the term, calling it La Cosa Nostra (in Italy, the article la is not used when referring to Cosa Nostra). In 1984, Mafia turncoat Tommaso Buscetta revealed to anti-mafia Italian magistrate Giovanni Falcone that the term was used by the Sicilian Mafia, as well. Buscetta dismissed the word "mafia" as a mere literary creation. Other defectors, such as Antonino Calderone and Salvatore Contorno, confirmed the use of Cosa Nostra by members. Mafiosi introduce known members to each other as belonging to cosa nostra ("our thing") or la stessa cosa ("the same thing"), meaning "he is the same thing as you – a mafioso." The Sicilian Mafia has used other names to describe itself throughout its history, such as "The Honoured Society". Mafiosi are known among themselves as "men of honour" or "men of respect". Cosa Nostra should not be confused with other mafia-type organisations in Southern Italy, such as the 'Ndrangheta in Calabria, the Camorra in Campania, or the Sacra Corona Unita and Società foggiana in Apulia. Overview In 1876, Leopoldo Franchetti described the Sicilian Mafia as an "industry of violence". In 1993, the Italian sociologist Diego Gambetta described it as a
