In 806 BC, Adad-nirari III took the reins of power from Semiramis. He invaded the Levant and subjugated the Arameans, Phoenicians, Philistines, Israelites, Neo-Hittites, Moabites and Edomites. He entered Damascus and forced tribute upon its Aramean king Ben-Hadad III. He next turned eastward to Iran, and subjugated the Persians, Medes and the pre Iranian Manneans, penetrating as far north east as the Caspian Sea. He then turned south, forcing Babylonia to pay tribute. His next targets were the migrant Aramean, Chaldean and Sutu tribes, who had settled in the far south eastern corner of Mesopotamia, whom he conquered and reduced to vassalage. Then the Arabs in the deserts of the Arabian Peninsula to the south of Mesopotamia were invaded, vanquished and forced to pay tribute also.
