Nikhor expressed himself favorable to the acceptance of these terms; and, after an exchange of hostages, Vahan visited his camp and made arrangements with him for the solemn ratification of peace on the aforesaid conditions.

An edict of toleration was issued, and it was formally declared that "every one should be at liberty to adhere to his own religion, and that no one should be driven to apostatize." Upon these terms peace was concluded between Vahan and Nikhor, and it was only necessary that the Persian monarch should ratify the terms for them to become formally binding.
While matters were in this state, and the consent of Balas to the terms agreed upon had not yet been positively signified, an important revolution took place at the court of Persia.

Zareh, a son of Perozes, preferred a claim to the crown, and was supported in his attempt by a considerable section of the people.

A civil war followed; and among the officers employed to suppress it was Nikhor, the governor of Armenia.

On his appointment he suggested to Vahan that it would lend great force to the Armenian claims if under the existing circumstances the Armenians would furnish effective aid to Balas, and so enable him to suppress the rebellion.
