Adad-nirari's youth, and the struggles his father had faced early in his reign, caused a serious weakening for the Assyrian rulership over Mesopotamia, and gave way to the ambitions of the most officers, governors, and the local rulers.

According to Adad-nirari's inscriptions, he led several military campaigns with the purpose of regaining the strength Assyria enjoyed in the times of his grandfather Shalmaneser III.

According to the eponym canon, he campaigned in all directions until the last of his 18 years of reign (783 BC), and he was the builder of the temple of Nabu at Nineveh.
Among his actions was a siege of Damascus in the time of Ben-Hadad III in 796 BC, which led to the eclipse of the Aramaean Kingdom of Damascus and allowed the recovery of Israel under Jehoash (who paid the Assyrian king tribute at this time) and Jeroboam II.

Despite Adad-nirari's vigour, Assyria entered a several-decades-long period of weakness following his death.
