Ashur-dan III (Neo-Assyrian cuneiform: , meaning "Ashur is strong") was the king of the Neo-Assyrian Empire from 773 BC to his death in 755 BC. Ashur-dan was a son of Adad-nirari III (811–783 BC) and succeeded his brother Shalmaneser IV as king. He ruled during a period of Assyrian decline from which few sources survive. As such his reign, other than broad political developments, is poorly known. At this time, the Assyrian officials were becoming increasingly powerful relative to the king and at the same time, Assyria's enemies were growing more dangerous. Ashur-dan's reign was a particularly difficult one as he was faced with two outbreaks of plague and five of his eighteen years as king were devoted to putting down revolts. Biography Ashur-dan III was a son of Adad-nirari III (811–783 BC). He succeeded his brother Shalmaneser IV as king in 773 BC. Shalmaneser IV's reign began an obscure period in Assyrian history from which little information survives, a period that also fully covers Ashur-dan III's reign, which has a result is very poorly known. During this period, the Neo-Assyrian Empire experienced a period of decline. In particular, the power of the king himself was being threatened due to the emergence of extraordinarily powerful officials, whom while they accepted the authority of the Assyrian monarch in practice acted with supreme authority themselves and began to issue their own inscriptions, similar to those of the kings. Such inscriptions by officials are more common from this time than inscriptions from the kings themselves. At the same time, the enemies of Assyria grew stronger. This period of Assyrian decline for instance coincided with the peak of the northern Kingdom of Urartu. It was customary for an Assyrian king to campaign every year, but Ashur-dan stayed in Assyria in four of the years of his reign, perhaps a sign of domestic instability. Only a single fragmentary royal inscription, on a clay cone, survives from Ashur-dan. This badly preserved inscription describes some restoration work on the main courtyard of the main temple in the city of Assur, dedicated to the Assyrian national god Ashur. Another inscription, a dedication on a bronze statue mentioning the name Ashur-dan, was previously believed to come from Ashur-dan III's time, but it is almost certainly instead from the time of the earlier Ashur-dan I (1179–1134 BC). Inscriptions from after Ashur-dan's reign that mention him include the Assyrian King List
