Адад-нирари III
Shalmaneser III (858–823 BC) attacked and reduced Babylonia to vassalage, and defeated Aramea, Israel, Urartu, Phoenicia and the neo Hittite states, forcing all of these to pay tribute to Assyria. Shamshi-Adad V (822–811 BC) inherited an empire beset by civil war which he took most of his reign to quell. He was succeeded by Adad-nirari III who was merely a boy. The Empire was thus ruled by the famed queen Semiramis until 806 BC. In that year Adad-nirari III took the reins of power. After his premature death, Assyria failed to expand further during the reigns of Shalmaneser IV (782–773 BC), Ashur-dan III (772–755 BC) and Ashur-nirari V (754–746 BC).
