List giving Ashur-nirari a reign lasting 10 years. Since the Assyrians counted reign lengths from the first full year of a king, Ashur-nirari's first year was reckoned to be 754 BC which means he would have ruled for 10 years only if he died in 744 BC. The Assyrian King List is however not without known errors and there are for some earlier kings discrepancies between different versions of the list.
