Human species supremacy is one of the most persistent fictions at work in the field of modern British imperial history today. This open access collection challenges that assumption, and investigates what histories of empire look like if reimagined as the effect of biocultural, chemical and cultural processes, rather than the result of effects by humans that have been visited upon cultural landscapes, fauna and biomes. In understanding the boundaries between human and nonhuman worlds as porous and open to mutual transformation, and foregrounding interspecies interactions, Biocultural Empire seeks to understand the conditions of imperial power, experience and knowledge as a remix of 'nature' and 'culture'. Bringing empire's 'biocultural histories' to the fore, it asks imperial historians to reckon with an interpretative framework which refuses the sovereignty and boundedness of the imperial subject by seeing it as inseparable from its social and ecological formations. Through this biocultural framework this collection highlights how relentlessly the human species bias of western liberal thought persists at the heart of imperial projects and their histories, and offers a new anti-colonial method that represents a significant intervention in the field of British imperial history.
