Durkheim, Weber and Marx discussed the macro-sociological relationship between law and society in a positivist framework. Marx and Weber primarily focused on the relationship between law and political economy. While the classical sociologists like Durkheim, Weber and Marx provided important contributions in terms of the changing role of the law and its relation to social change, Eugene Elrich, Nicholas Timasheff and George Gurvitch provided the theoretical competence for the sociology of law during the 20thcentury. As Ehrlich was an Austrian lawyer, he lived in the Austro-Hungarian Empire at that time. His work dating back to 1913 and entitled Fundamental Principles of the Sociology of Law has been translated into many languages and has become one of the masterpieces of the sociology of law.
