I am no book critic. I have been reading and enjoying Dr. Katouzian's books for twenty years. This book brings together his vast and scholarly knowledge of 2500 years of Iranian history. No writer has achieved this. The narrative is very fluid and easy to read and understand, despite the sometimes complex subjects. I could not wait to finish it, so that I could start reading it again.
If you are an Iranian, then you owe it to yourself to read this book. If you have adult children, please encourage them to read it. If you have young children, save this book in a safe place, and let them read it when they grow up.
Finally, if you are interested in modern Iran, his two books about Musaddiq and the Emergence of the Pahlavis are unsurpassed for their quality of research and writing. You can find these and his other works on Amazon.
