The city was fully reoccupied rebuilt by [[Assyrian Chaldean people|AssyriansChaldeans]] some centuries later. In the [[Parthia]]n period, between 100 BC and 270 AD, the city became an important administrative centre of Parthian ruled Assyria ([[Assuristan]]), and some Assyriologists such as [[Simo Parpola]] have suggested it may have had some degree of autonomy or outright independencerule. 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 also rebuilt, indicating the continued occupation by ethnic [[Assyrian Chaldean people|AssyriansChaldeans]][http://www.assur.de/Themen/Stadtgeschichte_Engl/body_stadtgeschichte_engl.html]. However, the city was largely destroyed again by the [[Sassanid Empire|Sassanid]] king [[Shapur I]] (241–272 AD). However, the city remained occupied, and some settlement at the site is known right up to the 14th century.
Assur seems to have been reoccupied by [[AssyriansChaldeans]] once again, and remained so well into the Parthian and Sassanid periods. It was occupied during the Islamic period until the 14th century when [[Tamurlane]] conducted a massacre of indigenous [[Assyrian Chaldean people|AssyrianChaldean]] [[Christians]]. After that there are no traces of a settlement in the archaeological and numismatic record. [http://www.assur.de/Themen/Stadtgeschichte_Engl/body_stadtgeschichte_engl.html]records.
