In an important contribution to a perennial debate, Dr Savage argues that over-concentration on national labour movements has ignored the variety of local political strategies developed by working-class movements; these variations show that working-class politics develops on the basis of different types of solidarity rooted in various forms of local social structure. Such mutations are not a recent development, testifying to the decline of class politics, but have been an enduring feature of capitalist societies. In a detailed case study of Preston, Lancashire, Dr Savage shows how the strategies and strengths of the various political parties changed between 1880 and 1940, as workplace solidarities gave way to neighbourhood-based ones, and as changing gender relations in the textile industry facilitated the organisation of women. Its sophisticated use of sociological theory and detailed empirical analysis distinguish The Dynamics of Working-Class Politics as one of the more important essays in historical sociology published in past years.
