After two centuries for which sources reveal nothing, the Middle Elamite period opened with the rise to power of the Anzanite dynasty, whose homeland probably lay in the mountains northeast of modern Khūzestān. Political expansion under Khumbannumena (c. 1285–c. 1266 BC), the fourth king of this line, proceeded apace, and his successes were commemorated by his assumption of the title “Expander of the Empire.” He was succeeded by his son, Untash-Gal (Untash [d] Gal, or Untash-Huban), a contemporary of Shalmaneser I of Assyria (c. 1274–c. 1245 BC) and the founder of the city of Dūr Untash (modern Choghā Zanbīl). In the years immediately following Untash-Gal’s reign, Elam increasingly found itself in real or potential conflict with the rising power of Assyria. Tukulti-Ninurta I of Assyria campaigned in the mountains north of Elam in the latter part of the 13th century BC. The Elamites under Kidin-Khutran, the second king after Untash-Gal, countered with a successful and devastating raid on Babylonia. In the end, however, Assyrian power seems to have been too great. Tukulti-Ninurta managed to expand, for a brief time, Assyrian control well to the south in Mesopotamia. Kidin-Khutran faded into obscurity, and the Anzanite dynasty came to an end (Source: Britanica).
