The Battle of Niḫriya was the culminating point of the hostilities between the Hittites and the Assyrians for control over the remnants of the former empire of Mitanni in Upper Mesopotamia, in the second half of the 13th Century BC.
When Hittite king Šuppiluliuma I (r. c. 1344–1322 BC) conquered Mitanni, he created two provinces (Aleppo and Carchemish), and distributed the large part of territories of this kingdom among his allies.
During the reign of the Hittite king Muršili III (better known as Urḫi-Teššub), Ḫanigalbat was subjugated by the Assyrians, who now advanced to the East bank of the Euphrates.
The Hittites considered Assyrian involvement to be a clear attack on the frontiers of their empire and took to arms under King Tudḫaliya IV (r. c. 1237–1209 BC), Ḫattusili's son and successor.
