Balash I, the wise Parthian king died on July, 30, 77 A.D. after 25 years of reign. One year before his death, Balash had ordered collection and compilation of Avesta. After him, Ardeshir Babakan ordered continuation and completed work on Avesta. However, the original Avesta is a dynamic product of continuous efforts by Zoroastrian theologists with several volumes and versions. After Balash died, Mehestan could not decide on electing a new king and therefore Iran was at the verge of entering a political crisis.
