As a student of history, I have always been fascinated by the career of Chandragupta Maurya, one of the greatest of kings, conquerors and administrators the world has produced. It is indeed strange that such a great personage should have passed almost unnoticed by historians, for there is so far, to my knowledge, not a single book in English describing exclusively his Achievements, I was aware of my incompetence to take up this task, yet I thought I might make an attempt. This small monograph is the result. In it, I have tried to describe, in a brief compass, the life and career of Chandragupta making use of all the original sources I could lay my hands upon. I have deviated from the accepted views where I found better evidence to the contrary. For instance, I have accepted the Jain date for the coronation of Chandragupta as it is better supported by facts than the date hitherto generally accepted. In some matters, of course, it is difficult to achieve any kind of finality till further evidence comes to notice, for example in the case of the pre-Maurya history of Magadha; in such cases I have simply mentioned the probabilities without emphasising the correctness of my views.
