This exploration of the full diversity of the Italian Antimafia draws on primary sources and interviews to provide a complete analysis of social, political and grassroots efforts since 1922. The murders of judges Falcone and Borsellino in 1992 caused an institutional crisis in Italy, aggravated by evidence of rampant corruption in political and business life. Since then, exceptional law enforcement successes have been undermined by inadequate efforts to address the underlying social and economic conditions that facilitate the expansion of the Mafia. This study looks at Antimafia initiatives within the context of international initiatives against organized crime.
