This paper examines labour disputes in London between 1790 and 1870, based on a systematic coverage of working-class newspapers. Disputes were classified by type, cause and trade. Evidence exists for 294 disputes, the large majority of which were strikes. The incidence of disputes roughly paralleled cyclical and seasonal fluctuations in the economy. Wage claims were the main cause for conflict, although interpretation of such disputes needs to be related to price movements. The most serious disputes were associated with significant changes in control over employment and the labour process. Skilled and unskilled workers were involved in disputes, both taking advantage of specific circumstances to exert power at the workplace. The extent to which London was prone to disputes is discussed and tentative comparisons drawn with other regions in Britain.
