Marduk-apla-iddina II (the biblical Merodach-Baladan, also called Marduk-Baladan, Baladan and Berodach-Baladan. lit. Marduk has given me an Heir.) (reigned 722 BC – 710 BC, 703 BC – 702 BC) was a Chaldean prince who usurped the Babylonian throne in 721 BC. Marduk-apla iddina II was also known as one of the kings who maintained Babylonian independence in the face of Assyrian military supremacy for more than a decade.
Sargon of Assyria repressed the allies of Marduk-apla-iddina II in Elam, Aram and Israel and eventually drove (ca. 710 BC) him from Babylon. After the death of Sargon, Marduk-apla-iddina II briefly recaptured the throne from a native Babylonian nobleman. He reigned nine months (703 BC – 702 BC). He returned from Elam and ignited rebellion in Babylonia. He was able to enter Babylon and be declared king again. Nine months later he was defeated near Kish by the Assyrians, but managed to flee to Elam. He died in exile a couple of years later.
