According to the Assyrian King List [http://oracc.museum.upenn.edu/riao/kinglists/assyriankinglist/assyriankinglist/index.html#Mitanni], Nūr-ili son of Enlil-nāṣir I [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/belubanidynasty/enlilnasiri/index.html], ruled Assyria for twelve years (probably during the first half of the 15th century BCE). He is also mentioned in the Synchronistic King List [http://oracc.museum.upenn.edu/riao/kinglists/synchronistickinglist/index.html#List]. Due to the poor state of preservation of the passage in which Nūr-ili's name appears, the name of his counterpart in Babylonia is not known (name completely missing). To date, no inscription of this Assyrian ruler has been found.
