oct 18, 609 BC - Battle at Harran

Description:

Over the course of Sinsharishkun's reign, the Neo-Assyrian Empire had been irreversibly weakened. A revolt in 626–620 BC had seen the loss of the empire's southern provinces to the newly formed Neo-Babylonian Empire and war against its king Nabopolassar and the Medes proved disastrous for Assyria; leading to sacks and destructions of the important cities of Assur and Nineveh in 614 BC and 612 BC respectively.

After the loss of these cities and the death of Sinsharishkun, Ashur-uballit II rallied what remained of the Assyrian army at Harran where, bolstered by an alliance with Egypt, he ruled for three years.
His identification as "king of Assyria" comes from Babylonian sources.
Contemporary Assyrian inscriptions suggest that the Assyrians saw Ashur-uballit as their legitimate ruler, but continued to refer to him as "crown prince" seeing as he could not undergo the traditional Assyrian coronation ceremony at Assur and thus hadn't formally been bestowed with the kingship by the Assyrian chief deity, Ashur.
His rule at Harran came to an end when the city was seized by Medo-Babylonian forces in 610 BC.
Ashur-uballit's attempt at retaking it in 609 BC was repulsed whereafter he is no longer mentioned in contemporary chronicles, signalling the end of the ancient Assyrian monarchy.
