During the past twenty years historical investigations of crime and criminal justice have increased considerably. This new subfield has been hailed enthusiastically by many of its practitioners: Douglas Hay considers it one that offers a key to ‘unlocking the meanings of eighteenth century social history.’ John Styles and John Brewer view the study of crime and law as a ‘point d'appui for a social history approach that embraces both the history of society and the issues of power and authority, an approach, in other words, that resolves the “crisis of social history.”’ Moreover, Marzio Romani describes this research as one that utilizes crime as a 'symptom,’ as a link between ‘conjuncture’ and ‘structure.’
