Ashur-Dan was succeeded by his son, Adad-nirari II (911-891 BC). He continued to campaign repeatedly in areas that his father had attacked, expanding on his father's achievements. He ruled two years less than his father, but the number and range of his military campaigns were greater. To the west he marched as far as the Balikh river, to the south as far as the middle Euphrates, to the north as far as the southern regions of Lake Van, and to the east he penetrated the Zagros mountains. Three versions of his annals are known. Altogether the annals cover campaigns from the accession to the eighteenth regnal year. Other kings that followed his strategies and ideology were Tukulti-Ninurta II, son of Adad-nirari II; Ashurnasripal II, son of Tukulti-Ninurta II; and Shalmaneser III, son of Ashurnasripal II.
