The Assyrian King List [http://oracc.museum.upenn.edu/riao/kinglists/assyriankinglist/index.html] (AKL) records that Akiya was the twenty-ninth ruler of Aššur; his name is preserved in two copies of that text, the Khorsabad List [http://oracc.museum.upenn.edu/riao/kinglists/assyriankinglist/khorsabadlist/index.html] and the SDAS List [http://oracc.museum.upenn.edu/riao/kinglists/assyriankinglist/sdaslist/index.html]. Akiya is said to have been succeeded by Kikkiya [http://oracc.museum.upenn.edu/riao/fromcolonytocitystate23341809bc/sargonicanduriiiperiods/kikkiya/index.html], who was in turn followed on the throne by Puzur-Aššur I [http://oracc.museum.upenn.edu/riao/fromcolonytocitystate23341809bc/puzurashurdynasty/index.html]; the AKL does not record the familial relationships between these three individuals. He is one of six rulers "[who(se names) appear on] bricks, (but) whose eponyms are not known" (see the introduction to the AKL). This scribal notation offers some insight into the methodological challenges faced by the composers of the AKL: the lack of eponyms (līmus [http://cdli.ox.ac.uk/wiki/doku.php?id=assyrian_eponyms_limmu]) for Akiya's tenure as ruler meant that the length of his reign could not be calculated. While the exact dates of Akiya's reign are uncertain, he seems to have exercised authority immediately before, or possibly after, the end of Ur's dominion over Aššur, at the end of the third millennium. It is possible that he was a governor during the Ur III period.
Not a single royal inscription of Akiya has yet been found at Aššur, despite the fact that the AKL (see above) states that building inscriptions were commissioned by him on bricks.
