The Nonconformists of England and Wales, the Protestants outside the Church of England, were particularly numerous in the Victorian years. From being a small minority in the eighteenth century, they had increased to represent nearly half the worshipping nation by the middle years of the nineteenth century. These Methodists, Congregationalists, Baptists, Quakers, Unitarians, and others helped shape society and made their mark in politics. This book explains the main characteristics of each denomination and examines the circumstances that enabled them to grow. It evaluates the main academic hypothesis about their role and points to signs of their subsequent decline in the twentieth century. Here is a succinct account of an important dimension of the Christian past in Britain.
