Academic consensus has yet to be reached about when exactly Smenkhkare ruled as pharaoh and where he falls in the timeline of Amarna. In particular, the confusion of his identity compared to that of Pharaoh Neferneferuaten has led to considerable academic debate about the order of kings in the late Amarna Period.
Aidan Dodson suggests that Smenkhkare did not have a sole reign and only served as Akhenaten's co-regent for about a year around Regnal Year 13.
James Peter Allen once depicted Smenkhkare as the successor to
Neferneferuaten in 2009. and Marc Gabolde has suggested that after Smenkhkare's reign, Meritaten succeeded him as Neferneferuaten. But after the discovery of a Year 16 date for Akhenaten's Great King's Wife, Nefertiti, which established that she was still alive in Akhenaten's Year 16, Professor J.P. Allen updated his opinion and accepted the hypothesis that Neferneferuaten must be
Nefertiti herself in a published
GM 249 (2016) paper titled “The Amarna Succession Revised": :"The evidence indicates Smenkhkare ruled only about a year at most....Smenkhkare's premature death probably no later than Akhenaten's Regnal Year 14 left only the one-to-four year old heir Tutankhuaten as putative heir....Tutankhamun must have been considered too young to be named coregent in his father's stead....To safeguard Tutankhamun's accession, Akhenaten also appointed a female coregent Ankheperure Neferneferuaten, to oversee the transition and probably to instruct him in the new religion. In 2009, I argued that this coregent was Akhenaten's fourth daughter, Neferneferuaten, both because it seemed a logical progression in his attempts to produce a son within each of his daughters as they reached puberty, and because evidence was lacking that the other Neferneferuaten, Nefertiti, was still alive in Akhenaten's final years. The Year 16 inscription noted [for the existence of Akhenaten's wife] at the beginning of this article solves the latter problem, and I (and my students) now think it likeliest that the coregent was in fact, Nefertiti. The arguments for this are more compelling than they are for the daughter...Since Nefertiti was still chief queen in Regnal Year 16 [of Akhenaten], her Year 3 as pharaoh must have occurred two years after Akhenaten's death, and it was within those two years that the first steps towards reconciliation with
Amun occurred."
Co-regency with Akhenaten Per Dodson's theory, Smenkhkare served only as co-regent with Akhenaten and never had an individual rule and Nefertiti became co-regent and eventual successor to Akhenaten. Smenkhkare and Meritaten appear together in the tomb of
Meryre II at Amarna, rewarding Meryre. There, Smenkhkare wears the
khepresh crown, however he is called the son-in-law of Akhenaten. Further, his name appears only during Akhenaten's reign without certain evidence to attest to a sole reign. The names of the king have since been cut out but were recorded around 1850 by
Karl Lepsius. Additionally, a calcite "globular vase" from
Tutankhamun's tomb displays the full double cartouches of both pharaohs. However, this is the only object known to carry both names side-by-side. This evidence has been taken by some Egyptologists to indicate that Akhenaten and Smenkhkare were
co-regents. However, the scene in Meryre's tomb is undated and Akhenaten is neither depicted nor mentioned in the tomb. The jar may simply be a case of one king associating himself with a predecessor. The simple association of names, particularly on everyday objects, is not conclusive of a co-regency.
Smenkhkare as successor to Neferneferuaten Arguing against the co-regency theory, Allen suggests that Neferneferuaten followed Akhenaten and that upon her death, Smenkhkare ascended as pharaoh. Allen once proposed that following Nefertiti's death in Year 13 or 14, her daughter
Neferneferuaten-tasherit became Pharaoh Neferneferuaten. However, a hieratic inscription discovered at the limestone quarry at Deir Abu Hinnis suggests that Nefertiti was alive in Akhenaten's Year 16, undermining this theory. There, Nefertiti is referred to as the pharaoh's Great Royal Wife. As noted above, in an updated 2016
Gottinger Miszellen paper titled “The Amarna Succession Revised" published in light of Vander Perre's discovery, J.P. Allen now accepts that the female pharaoh was not Akhenaten's daughter
Neferneferuaten Tasherit but rather Queen Nefertiti herself who is known to have used the Neferneferuaten title in her lifetime as Akhenaten's queen and likely have proclaimed herself as a female king of Egypt when her husband died. Furthermore, work is believed to have halted on the Amarna tombs shortly after Year 13. Therefore, the depiction of Smenkhkare in Meryre's tomb must date to no later than Year 13. For him to have succeeded Neferneferuaten means that aside from a lone wine docket, he left not a single trace over the course of five to six years.
Meritaten as successor to Smenkhkare In comparison to the theories mentioned above,
Marc Gabolde has advocated that Smenkhkare's Great Royal Wife, Meritaten, became Pharaoh Neferneferuaten after her husband's death. The main argument against this is a box (Carter 001k) from Tutankhamun's tomb that lists Akhenaten, Neferneferuaten, and Meritaten as three separate individuals. There, Meritaten is explicitly listed as Great Royal Wife. Further, various private stelae depict the female pharaoh with Akhenaten. However under this theory, Akhenaten would be dead by the time Meritaten became pharaoh as Neferneferuaten. Gabolde suggest that these depictions are retrospective. Yet since these are private cult stelae it would require a number of people to get the same idea to commission a retrospective, commemorative stela at the same time. Allen notes that the everyday interaction portrayed in them more likely indicates two living people. ==Identity and confusion over regnal name==
