Since the beginning of the last century Weber argued the indissoluble link between sociology and history. His approach saw the relationship between history and sociology as based on (a) mutual and essential support, and (b) logical priority, according to which, paraphrasing sociologist Alessandro Cavalli, “sociology without history is blind, history without sociology is mute.” The lesson of the «Annales» definitively confirmed the indissoluble link between history and social sciences, on the basis of a strongly and strategically interdisciplinary analysis. However, at present sociology and history continue to cooperate all too rarely in the context of interdisciplinary research. There is no question that social conflict – and social ambiguities – is a common ground of research both for sociology and history. Through the analysis of social conflict this book aims at providing argumentative issues concerning the above link, and showing meaningful convergences between the two disciplines. This in order to offer innovative spaces of discourse around the theory and methodology of research, and some areas of yesterday and today social conflicts.
