Dakhamunzu (properly Daḫamunzu) is the name of an Egyptian queen known from the Hittite annals The Deeds of Suppiluliuma, which were composed by Suppiluliuma I's son Mursili II. The identity of this queen has not yet been established with any degree of certainty and Dakhamunzu has variously been identified as either Nefertiti, Meritaten or Ankhesenamen. The identification of this queen is of importance both for Egyptian chronology and for the reconstruction of events during the late Eighteenth Dynasty.
However, in recent years it has been noted that Dahamunzu may be the Hittite phonetic rendition of the Egyptian ta hemet nesu, 'the king's wife', and thus is simply the equivalent of addressing her as the equivalent of 'queen'. If so, then Dahamanzu is not a proper name at all and thus not a mysterious synonym for any of the queens discussed here, and is instead only a title. See below on this page.[1]
The episode in The Deeds of Suppiluliuma that features Dakhamunzu is often referred to as the Zannanza affair, after the name of a Hittite prince who was sent to Egypt to marry her.
