The city revived during the Parthian Empire period, particularly between 150 BC and 270 AD, being resettled and becoming an administrative centre of Parthian-ruled Assuristan. Assyriologists Simo Parpola and Patricia Crone suggest Assur may have had outright independence in this period. Other polities such as Beth Garmai, Beth Nuhadra and Adiabene also flourished due to the fact that the Parthians exercised only loose or intermittent control of Assyria. New administrative buildings were erected to the north of the old city, and a palace to the south. The old temple dedicated to the national god of the Assyrians Assur (Ashur) was rebuilt, as were temples to other Assyrian gods.
