 By the end of the 7th century BC, the Assyrian Empire, weakened by the successive revolts, had been destroyed by the Median Empire.As the Babylonians finally defeated the Assyrians at Carchemish, much of Lebanon was already in their hands, since much of it was seized from the collapsing Assyrian kingdom.In that time two Babylonian kings succeeded the throne, Nabopolassar who focused on ending Assyrian influence in the region, and his son Nebuchadnezzar II whose reign witnessed several regional rebellions, especially in Jerusalem.
