I was thinking about some of the recent threads on butterflied Islam; one possibility mentioned was that the Arabs embraced Judaism.
It got me thinking - what if there was a Jewish "caliphate" - an Arab based, Perso-Byzantine influenced empire stretching roughly from the Oxus to the Nile (or beyond) and constituting the great "other" for the Christian powers.
Now, obviously this is an interesting TL in all sorts of ways, but I have a very specific question - assume that the empire is ruled from Jerusalem, rather than Damascus or Ctesiphon (City of David and all that). In addition, the Third Temple is built and Jerusalem becomes the spiritual capitol of the Middle East, with pilgrimages to Jerusalem replacing the Hajj and yearly inflating Jerusalem's population by, eventually, hundreds of thousands if not millions. (Yes, Temple-era Judaism had yearly pilgrimages, which is even more dramatic than the once-in-a-lifetime Hajj).
Alright. Jerusalem has a long history as a spiritual center and, off and on, a sovereign capital of a small state; but this is orders of magnitude bigger. Can a city so far from any major source of water ever get as big as OTL's medieval Damascus or Baghdad? I know that Jerusalem was positively tiny well into modern times IOTL; can it be an Imperial Capital and super-city? And if so, what does it look like?
