This book aims to describe and analyse the political and social thinking, attitudes and actions of the English Protestant churches since the late eighteenth century. It focuses in particular on how they have responded to the plight of the least privileged members of society - individuals and groups marginalised or placed at a disadvantage as a consequence of their ethnicity or socioeconomic circumstances. These have been the nation's underdogs, the most powerless of its inhabitants, and this book explores the involvement of the churches in attempting to create a fairer society, from the anti-slavery campaign to the present day.
