The list of Assyrian kings is compiled from the Assyrian King List, an ancient kingdom in northern Mesopotamia (modern northern Iraq) with information added from recent archaeological findings. The Assyrian King List includes regnal lengths that appear to have been based on now lost limmu lists (which list the names of eponymous officials for each year). These regnal lengths accord well with Hittite, Babylonian and ancient Egyptian king lists and with the archaeological record, and are considered reliable for the age.
