The Disruption in the Church of Scotland is examined within the context of changes which had taken place in the form of industrial production, whereby the city as a centre of manufacturing had replaced the domestic production of the countryside. The concomitant changes in the social structure, and the divisions which resulted within the old ruling families, are probed. The social patterns of adherence to the Established and Free Churches are analysed in detail, and the subsequent development of the Free Church is examined in terms of the social support it enjoyed in 1843.
