Eric Hobsbawm's concept of ‘social banditry’, as presented in Bandits of 1969, is probably the single most influential idea in the modern study of bandits and outlaws. Key to Hobsbawm's argument is the assumption of a more or less direct relation between ‘a bandit's real behaviour and his subsequent myth’ – in other words, that the popular perception of bandits reflected the social reality of banditry, and that accordingly the Robin Hood myth had some basis in historical events. This article seeks to qualify some of the basic premises of Eric Hobsbawm's concept of social banditry by examining the context and process by which popular and official knowledge of banditry emerged. This analysis is based on a case-study of the thugs of early nineteenth-century colonial India. Though seldom described as such, thuggee is one of the best-documented instances of banditry historically speaking. This makes the findings and theoretical considerations made in connection with thuggee pertinent to banditry worldwide and during various periods. By focusing on issues of methodology it is hoped that a critical discussion of Hobsbawm's model, rather than just being a polemic deconstruction, may suggest a new approach to the study of banditry more generally.
