“There is no fixed principle or permanence in the administrative
subdivisions of Persia. Their separation or combination is regulated by the
ability or reputation of their governors, and by the scope that may be
conceded thereto by the confidence or the fears of the sovereign…. It
should further be remarked that no principle, geographical, ethnographical,
or political, appears to be adopted in determining the borders and sizes of
the various divisions, which vary in extent from a province larger than the
whole of England, to a small and decayed town with its immediate
surroundings.”
