'Bel-ibni' was a
Babylonian nobleman who served as
King of Babylon for several years as the nominee of the
Assyrian king
Sennacherib.
Sennacherib, believing that direct Assyrian rule was too costly, appointed Bel-ibni, a young Babylonian nobleman raised at the Assyrian court, King of Babylon in
703 BC.
The experiment with a native puppet king was hardly more successful than direct Assyrian control. Soon Bel-ibni was conspiring with the Chaldeans and Elamites against the Assyrians. After defeating the opposing coalition in
700 BC, Sennacherib deposed Bel-ibni and carried him off to Assyrian exile, replacing him with Sennacherib's own son,
Ashur-nadin-shumi.
