Highly recommend it as well.Fate of Empires by Glubb Pasha or John Glubb. Interesting Brit who served the Jordan legion and describes the tendencies of societies in decline. One particularly interesting thing I found was the presence of singers in the Muslim world, which annoyed the Caliph of Baghdad. However, every season the singers would return.
"The heroes of declining nations are always the same—the athlete, the singer or the actor. The word ‘celebrity’ today is used to designate a comedian or a football player, not a statesman, a general, or a literary genius."
I use him as one of my go-to stories. You can tell it as a captivating story on the cyclical nature of history.
