This article surveys the state of the research undertaken to date on Calabrian organised crime, now known as the 'Ndrangheta. Using continuous reference to the historiography of the Sicilian Mafia, and prompted in particular by a preliminary review of various documentary sources, it also poses questions and develops theories that will need further study and reflection. The first section addresses the classic image of the 'Ndrangheta, as crime linked to the traditional values of the Calabrian rural world. It is suggested that the interweaving of this criminal phenomenon and traditional society is more complex than a relationship of identification between the two, and results from the deliberate pursuit of criminal objectives such as legitimisation and social control. Further problems are highlighted as attention is turned from issues regarding values to the socio-economic features of the ‘Picciotteria’, as the 'Ndrangheta was known prior to the 1950s. There is a discussion of the reasons for its success, the economic parasitism practised using positions of social intermediation, and the existence of formal structures distinct from traditional family bonds and community ties. The article's final section focuses on the relationship between the 'Ndrangheta and politics in the period after the Second World War. The paucity of research that specifically addresses the period between the war and the 1970s is highlighted; linked to this, approaches are suggested for investigating the nature of crime's penetration of politics, the relationship with the parties at the local level, and the ways in which the 'Ndrangheta was interpreted by these same political parties.
