When students of early nineteenth-century ecclesiastical history come to compile a religious ‘map’ of England, their attention will be drawn to a matter commented upon often enough by contemporaries, but almost entirely neglected now—the catastrophic decline in the influence of the Church in much of the countryside. The greatest triumphs of Nonconformity were won in the rural areas of Wales, and by the time of the religious census in 1851 English Dissenters had established a long lead over the Church in the East and North Ridings of Yorkshire, in Lincolnshire and Bedfordshire, were ahead in Huntingdonshire, and were within striking distance of drawing level in Northamptonshire, Buckinghamshire and Norfolk. In the southern and south-eastern counties the Church preserved its formal ascendancy, but often attracted a smaller proportion of the people to its services on census Sunday than in counties which were overrun by Dissent. The real tragedy for the Church in this period, it may be argued, was not that industrialisation concentrated people where her. endowments, manpower and accommodation were thinly spread, but that things went so badly where her resources were concentrated. It is the object of this paper to draw attention to this major question of ecclesiastical history and geography, and to suggest that part of the answer to it lies in the tithe question.
