Arbayistan

Hatra (; (); ) was an ancient city in Upper Mesopotamia located in present-day eastern Nineveh Governorate in northern Iraq. The ruins of the city lie northwest of Baghdad and southwest of Mosul. It is considered the richest archaeological site from the Parthian Empire known to date.

Arbāyistān ( [ʾrb]ystn; Middle Persian: Arbāyistān, Arāwastān, Arwāstān; Armenian: Arvastan) or Beth Arabaye (Syriac: Bēṯ ʿArbāyē) was a Sasanian province in Late Antiquity. Due to its situation and its road systems, the province was a source of income from commercial traffic, as well as a constant area of contention during the Roman–Persian Wars.
