Adad-nirari III
Azakh (today called İdil) is identified as the town of Ashikhu, or Asiḫu, which is earliest attested in an administrative note from the governor's archive at Tell Halaf, during the reign of Adad-nirari III, King of Assyria, in the late 9th and early 8th century BC. Azakh was later conflated with the neighbouring city of Bezabde, and led to its alternative Syriac name Beth Zabday.
