The first years of Shamshi-Adad's reign saw a serious struggle for the succession of the aged Shalmaneser. The revolt was led by Shamshi-Adad's brother
Assur-danin-pal, and had broken out already by 826 BC. The rebellious brother, according to Shamshi-Adad's own inscriptions, succeeded in bringing to his side 27 important cities, including
Nineveh. The rebellion lasted until 820 BC, weakening the Assyrian empire and its ruler; this weakness continued to reverberate in the kingdom until the reforms of
Tiglath-Pileser III. Later in his reign, Shamshi-Adad campaigned against Southern
Mesopotamia, and stipulated a treaty with the Babylonian king
Marduk-zakir-shumi I. In 814 BC, he won the
Battle of Dur-Papsukkal against the Babylonian king
Marduk-balassu-iqbi, and a few
Aramean tribes settled in
Babylonia. The extent of Shamshi-Adad's victory was such that he obtained the submission of the Babylonian king and, after obtaining booty from several Babylonian cities, he returned to Assyria with palace treasures and gods (i.e. the sacred representation of the gods). ==See also==
