James Mill's three volume History of British India was published from 1817 to 1818 and became an immediate success. A friend of Jeremy Bentham and a follower of utilitarianism, Mill focuses more on historical processes than human interest. He uses extensive sources rather than first-hand experience to create, as his preface claims, an 'objective' yet 'critical' history, often making harsh judgements of the country and its people within the context of a wider theoretical framework. He also criticises the British involvement in India and the process of conquest, colonization, and administration, the intention being to encourage the reader to a greater understanding of historical processes, ideas, and institutions with a view to encouraging thorough reform.
