[2] The king reigned for 45 years in the 14th century BC,[3][4] and was mentioned in the inventories of Ninegal, found in Qatna.
[5] A tablet from Qatna records him stationing an army of chariot archers in the city of Tukad, in Mount Lebanon.
[9] According to Richter, Adad-Nirari of Nuhašše ruled the second Syrian power after Mitanni,[10] and was removed by the Hittites which gave Qatna its independence back .
[11] This theory is debated; the Shattiwaza treaty between Mitanni and the Hittites mentioned Qatna independently from Nuhašše during the Hittite king Šuppiluliuma I's first Syrian war; If Qatna was part of the Nuhaššite kingdom, its submission to the Hittites would not have been mentioned separately.
[12] Jacques Freu rejected Richter's hypothesis; citing different arguments, he concluded that Adad-Nirari of Nuhašše was a contemporary of Idadnda of Qatna who ruled during the first Syrian war, a successor of the Qatanite Adad-Nirari.
