@caitlinrgreen Wonder what the distinction was between a caliphate & an emirate during this period. The one had a caliph & t'other an emir?
@Harry_cartoons This has some useful stuff, see section on Power especially: https://en.wikipedia.org/wiki/Abbasid_Caliphate … Also: https://en.wikipedia.org/wiki/Caliphate
@caitlinrgreen Thanks. Much obliged.....
@Harry_cartoons no problem :) But basically, yes, what you said, and the two meant different things :)
@caitlinrgreen Yes, think that's what I was groping for in the dark-difference between Emir & Caliph, which I shall proceed to read up on :)
