Normally there were three contemporary rulers of royal rank in eastern Iran and northwestern India: a "king of kings" in Iran, some junior member of his family associated with him, and another "king of kings" in India. The junior member in Iran usually became in due course the supreme ruler in India. The belief that the title "king of kings" was not used in Parthia from 88 to 57 led logically to the correct conclusion that the rulers of Iran and India were independent of Parthia; but at least one case of its use in Parthia in 64  is known.

In eastern Iran the ruler issued coins together with that member of the family associated with him in the government. The legend of the king is in Greek, and that of the prince, on the reverse, in Kharosthi; since the use of Kharosthi in this period is known from Arachosia only, we may infer that the prince governed that territory.
