Nabonassar (also Nabonasser, Nabu-nasir, Nebo-adon-Assur or Nabo-n-assar) founded a kingdom in
Babylon in
747 BC. This is now considered as the start of the
Neo-Babylonian Dynasty. At the time the
Assyrian Empire was in disarray through civil war and the ascendancy of other kingdoms such as
Urartu. An army commander involved in the civil war, who adopted the name
Tiglath-pileser III with his accession, won control of Assyria the following year
746 BC. Shortly thereafter he retook Babylon under the suzerainty of Assyria, and Nabonassar continued to rule as a vassal king for 14 years, until
734 BC.
