'In this meticulous toxicological assay of British India, David Arnold challenges us to rethink how we draw boundaries between the therapeutic and the poisonous, between purity and danger, and between European and Indigenous. Colonialism is refigured as the governance of poisons - and modernity turns into the titrating of toxicities. A revealing forensic study of poison as substance and metaphor under colonial rule, Toxic Histories also shows us how - and why - toxicity became a concept intrinsic to India's modernity. Thus Arnold traces the sad genealogy of our poisoned world.' Warwick Anderson, University of Sydney

'The idea of poison lurks below the surface of much of Indian history but it has rarely been investigated in its own right. In this path-breaking book, David Arnold demonstrates the importance of doing so. Exploring the practical uses and the ideological significance of poisons, Arnold shows how narratives of toxicity became central to the construction and evaluation of India's modernity. Brimming with fascinating insights, there is scarcely any aspect of Indian history which is not illuminated by this book.' Mark Harrison, University of Oxford

'Against the vast backdrop of India's pre-, colonial and post-colonial history, the eminent historian David Arnold asks the provocative question: do different places have their own toxic histories? In an outstanding display of scholarship, in equal measures subtle and sophisticated, full of striking and illuminating historical examples, and written with a clear sense of how his analysis might engage with critical understandings of our own toxic present, Arnold's answer is a satisfyingly complex 'yes'.' Ian Burney, University of Manchester
