This article provides information on the origins and development of the sociology of law in Italy. In general terms, it is said that sociology of law in Italy is a deeply rooted and well institutionalized scientific discipline. Italian studies in law and society usually appear in Italian, an idiom whose international diffusion does not correspond to its noble tradition. Italian titles seldom appear in scientific bibliographies, irrespective of the intrinsic significance and value of the writings with the only exception of the Spanish speaking area, where sociology of law developed later than in Italy and was therefore to a certain extent affected, in its origins, by the relatively large production already accumulated within the closest linguistic community. As a premise, it should be said that a sociological approach to law in Italy had an early flourishing in the second half of the 19th century, alongside the diffusion of Positivism in philosophy and general sociology. During the early 1960s, the period was dominated by neo-positivism in general philosophy, by open normativism and realism in jurisprudence and by theoretical functionalism and methodological empiricism in sociology.
