Giovanni Falcone contributed to shaping the story of crime in Italy. Together with Borsellino he tried to combat COSA Nostra or the mafia in Sicily with some financial investigation. By doing this, this judge succeeded in limiting the power of the leader of the Sicilian Mafia Toto Riina and showed the interconnection between corruption and broad violence. The attempt of fighting the power of Riina costed him his life, but permitted him to establish the biggest and the greatest process against the mafia within the Italian history.
