By exploring the dimensions of race, race relations and resistance, this book offers a new account of the British Empire's greatest failure and its most disturbing legacy. Using a wide range of published and archival sources, this study of racial discourse from 1870 to 1914 argues that race, then as now, was a contested territory within the metropolitan culture. Based on a wide range of published and archival sources, this book uncovers the conflicting opinions that characterised late Victorian and Edwardian discourse on the 'colour question'. It offers a revisionist account of race in science, and provides original studies of the invention of the language of race relations and of resistance to race-thinking led by radical abolitionists and persons of Asian and African descent living in the United Kingdom. The book will be of interest to students and scholars of race, colonialism and culture, and to a readership interested in the history of science and race, anti-slavery and humanitarian movements, and the roots of anti-racist resistance.
