Arbāyistān (Parthian: 𐭀𐭓𐭁𐭉𐭎𐭈𐭍 [ʾrb]ystn; Middle Persian: Arwāstān; Armenian: Arvastan)[1] 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.[2]
The province reached across Upper Mesopotamia toward the Khabur and north to the lower districts of Armenia; it bordered Adiabene in the east, Armenia in the north and Asoristan in the south. On the west, it bordered the Roman provinces of Osroene and Mesopotamia.[3] The principal city of the Arbayistan province was Nisibis and it also included the fortress of Sisauranon.[3]
