Asuristan

Asoristan (, , ), also known as Suristan, was the name of the Sasanian province of Assyria and Babylonia from 226 to 637 CE.

==Name== The Parthian name Asōristān (; also spelled Asoristan, Asuristan, Asurestan, Assuristan) is known from Shapur I's inscription on the Ka'ba-ye Zartosht, and from the inscription of Narseh at Paikuli. The region was also called several other names, mostly relating to its indigenous Assyrian inhabitants: Assyria, Athura, Bēṯ Nahren ( ), Bābēl/Bābil, and Ereḫ/Erāq. After the mid-6th century, it was also called Khwārwarān in New Persian. Although it is difficult to determine the true meaning of the renaming of southern Mesopotamia to "Assyria", it is possible that due to the Assyrian kingdom of Adiabene being in the north, it excluded the Assyrians further south and therefore the Persians named it accordingly to include the few million Semitic Mesopotamian people who were descendants of the ancient Assyrians south of Adiabene, contrary to the Greeks renaming Assyrians "Syrians", an Indo-European corruption of "Assyrians". At the very least, names associated with Assyria continued to be used and were not obsolete.
