First published in 1999, Andrew Chadwick provides an important new interpretation of British radical, suffrage-feminist and socialist movements during the first quarter of the twentieth century, based on analysis of their visions of democratic constitutional reform. He argues that a shared discourse of 'radical constitutionalism' allowed these groups to forge alliances based upon a common preoccupation with extending and improving constitutional democracy. This book is a significant contribution to current methodological debates around the importance of language and discourse in social and political history. It is the first detailed study to integrate material on three important constitutional campaigns of this era: the reform of the House of Lords, women's suffrage, and proportional representation. It will be of interest to students of British politics, social and political history, historical methodology and political theory.
