The Men who Ruled India

Originally Mason published a two-volume set : The Men Who Ruled India. Volume I: The Founders (1953) and The Men Who Ruled India. Volume II: The Guardians (1954). These two volumes were then distilled into this single volume The Men who Ruled India (1985).
Scholars may care to note that Mason used his diplomatic pseudonym Philip Woodruff when publishing the original two-volume set in the 1950s. And that this single volume published some thirty years later keeps the salients of the earlier works and extends their scope somewhat.
As a member of the administration which ruled the British Raj of India  Philip
Mason was eminently qualified to assess the lives of those who for three and a half centuries exerted so powerful an influence on India.
