Abstract
The paper examines changes in the organization of the British cotton industry from 1825 to 1850 in its core region of Lancashire and northeast Cheshire, using new data to delineate patterns of integration, specialization, and the adoption of new technology. The industry is usually assumed to have progressed from a rather specialized structure in 1825 to a highly integrated structure in 1850; much of the literature is devoted to explaining this trend. No such trend occurred, however, and the explanations are incorrect. An alternative view, focusing on technical change and profitability in spinning and weaving, is outlined briefly.
