Good history comes from a combination of sources: in this case, private papers ranging from Lord Curzon’s letters to the diary of a royal tutor; from archival records in Delhi and London, not to speak of parliamentary papers; art, and not just paintings by Ravi Varma, to understand how princes projected themselves; newspaper records, which contain debates and ‘live’ commentary; scholarly material on connected themes; and, of course, anecdotal information from biographies and memoirs, which add texture.
