This is something of a first. Instead of reviewing the books I want to focus on the author. David Morgan died in 2019 but left behind a significant body of work.
I first came across his book on Medieval Persia by chance last year when I was looking for books on the Arab Conquests. Purchased second hand, the first edition was both a bargain and a delight. With a clear, concise and approachable style the book dealt with all the rulers of post Arab Conquest Persia with aplomb.
