William F. Albright has dated his reign to 842 BC, while E. R. Thiele offers the date 841/840 BC.[2] As explained in the Rehoboam article, Thiele's chronology for the first kings of Judah contained an internal inconsistency that placed Ahaziah's reign one year after his mother Athaliah usurped the throne. Later scholars corrected this by dating these kings one year earlier,[3][4] so that Ahaziah's dates are taken as one year earlier than Thiele's in the present article.
