The international dimension of Cosa Nostra: a study on the different strategies to contrast Mafia between US and Italy ​

History teaches us that, since most ancient times an eternal struggle between good and evil, light and darkness, justice and crime, has been waged and never ceases to exist. The work carried out in this thesis, aims to study the phenomenon of organized crime, which has started to mark the world territory since the beginning of the 19th century. The origin of the historical and social path that this work deals with, in fact, begins right from the middle of the 19th century, when the first bands of Brigands made their appearance in the territories of southern Italy. The Brigants then became real criminal associations and grouped themselves in the so-called "Secret Societies". These Societies, precisely Secret, acted in secrecy and illegality. As time went by and society changed, secret societies changed shape, name and ideologies, first they were the Brigands, then the Carbonari, the Freemasons, and so on, but one thing never changed: the rules that these associations had . These organizations had precise rules for joining them. The entry into the associations took place through an initiation rite preceded by a period in which the new member was tested and observed by the boss, once accepted in the organization there was the rule of silence that governed sovereign, no one outside the members of the organizations could come know about internal affairs. Migratory phenomena and the industrial development of society led criminals to move from their homes, towards new horizons, from Sicily to America, throughout Europe up to Asia and Australia. This led to a globalization of the criminal phenomenon. The most discussed form of criminal organization in the world is that of the Mafia. The mafia was born in Italy, mainly in the territories of southern Italy, such as Sicily, Calabria and Campania, which gave birth to the triad of the Mafia’s organizations: Cosa Nostra, Camorra and ‘Ndrangheta. Cosa nostra, the Sicilian mafia, has always been the strongest and most indestructible mafia that has ever existed. Part of the Sicilian mafiosi, moved to America and gave birth to an American branch of Cosa Nostra, as strong as the original. The arms of the Mafia managed to penetrate any form of social and political activity, giving life to a corrupt society. The figure of the Mafia Boss was thus seen as a strong and valiant man, full of courage and indestructible. Sicilian society became stereotyped as a “Mafia society”, full of secret affairs, a stereotype that still today has not been defeated. The mafia phenomenon was widely opposed over time by astute men and women, who, contrary to the violent struggle that organized crime put in place, used and continue to use the judicial channels. During the course of the time of the fight against the mafia, as well as in Italy and also in America, many people lost their lives, the victims of the mafia were infinite, it is not possible to have an exact estimate. The anti-mafia deployments fight every day to free Sicily, Italy and the whole world from corruption, blackmail and the arrogance of the Mafia. Will all these deaths for justice, all these battles for freedom really serve to put an end to the mafia phenomenon'?
