The identity of the queen who wrote the letter is uncertain. She is called Dakhamunzu in the Hittite annuals, a possible transliteration of the Egyptian title Tahemetnesu (The King's Wife). Possible candidates are Nefertiti, Meritaten, and Ankhesenamun. Ankhesenamun seemed once likely since there were no candidates for the throne on the death of her husband, Tutankhamun, whereas Akhenaten had at least two legitimate successors. but this was based on a 27-year reign for the last 18th pharaoh Horemheb who is now accepted to have had a shorter reign of only 14 years. This makes the deceased Egyptian king appear to be Akhenaten instead rather than Tutankhamun. The phrase regarding marriage to 'one of my subjects' (translated by some as 'servants') is possibly a reference to the Grand Vizier Ay or a secondary member of the Egyptian royal family line. Since Nefertiti was depicted as powerful as her husband in official monuments smiting Egypt's enemies, she might be the Dakhamunzu in the Amarna correspondence as Nicholas Reeves believes. Ankhesenamun may have been pressured by Ay to marry him and legitimise his claim to the throne of Egypt (which she eventually did) This also might explain why she describes herself as 'afraid', especially considering the popular (but not widely accepted) theory that Ay had a hand in her husband's death. A CT scan taken in 2005 shows that he had badly broken his leg shortly before his death, and that the leg had become infected. DNA analysis conducted in 2010 showed the presence of malaria in his system. It is believed that these two conditions, malaria and leiomyomata, combined, led to his death. However, Ankhesenamun was not as powerful as Nefertiti to be able to choose her spouse from a foreign state.
