In the annals of the great Asshur-izirpal inscribed on the Nimrud monolith, that prince, while commemorating his war-like exploits, informs us that he set up his sculptures at the sources of the Tsupnat river alongside of sculptures previously set up by his ancestors Tiglath-Pileser and Tiglathi-Nin.

That Tiglathi-Nin should have made so distant an expedition is the more remarkable from the brevity of his reign, which only lasted for six years.

According to the Canon, he ascended the throne in the year B.C.

889; he was succeeded in B.C.883 by his son Asshur-izir-pal.
With Asshur-izir-pal commences one of the most flourishing periods of the Empire.

During the twenty-five years of his active and laborious reign.
