I am in the middle of reading Lost to the West: The Forgotten Byzantine Empire That Rescued Western Civilization and that is the exact situation that I am currently covering in the book.
And I am not even out of the AD500 period, and instead of Islamic hordes, they are both making deals with, and fighting, the Vandals.
The human condition, indeed.
So good to see another Freeper who READS, instead of parroting youtube videos. That sounds like a good one, it’ll go in mu queue.
