I generally like Jamestown stuff but this struck me as really weird.

Isn't a "Vilyat" a corruption of an Ottoman Turk administrative division? When did the Ottomans rule Daghestan ? Golden Horde, sure. Persians, definitely. Why would Wahabbist neo-salafi loons use antique Turkish terminology when a good Wahabbist would see Ottoman sanjaks as corrupt former oppressors of "true Islam" ?

Maybe I have missed something somewhere ?
