In this book, Anthony Williams investigates the history of Christian Socialist thought in Britain from the late nineteenth to mid-twentieth century. Through analysis of the writings of ten key Christian Socialists from the period, Williams reframes the ideology of Christian Socialism as a coherent and influential body of political thought - moving the study of Christian Socialism away from historical narratives and towards political ideology. The book sheds new light on a key period in British political development, in particular Williams demonstrates how the growth of the Christian Socialist movement exercised a profound impact on the formation of the British Labour party, which would go on to radically change 20th century politics in Britain.
