Sanakht (also read as Hor-Sanakht) is the Horus name of an ancient Egyptian king (pharaoh) of the Third Dynasty during the Old Kingdom. His chronological position is highly uncertain (though he is more likely to have reigned towards the end of the dynasty), and it is also unclear under which Hellenized name the ancient historian Manetho could have listed him. Many Egyptologists connect Sanakht with the Ramesside cartouche name Nebka. However, this remains disputed because no further royal title of that king has ever been found; either in contemporary source or later ones. There are two relief fragments depicting Sanakht originally from the Wadi Maghareh on the Sinai Peninsula. Identity Sanakht's identity and position in the Third Dynasty is not entirely clear and remains the subject of debate. While Sanakht's existence is attested by seal fragments from mastaba K2 at Beit Khallaf and a graffito, his position as the founder of the Third Dynasty, as recorded by Manetho and the Turin Canon, has been seriously undermined by recent archaeological discoveries at Abydos. These discoveries establish that it was likely Djoser who helped bury—and thus succeed—Khasekhemwy, rather than Sanakht. This is determined from seals bearing Djoser's name found at the entrance to the latter's tomb. Proponents of the theory that Sanakht was nonetheless the founder of the dynasty object that the presence of Djoser's seals in Khasekhemwy's tomb only shows that Djoser conducted cultural rituals in honor of this king, and does not necessarily imply that Djoser was Khasekhemwy's immediate successor. Sanakht could then have married Queen Nimaethap, with Nimaethap being the daughter of Khasekhemwy rather than his wife. Together with Sanakht, they could be the parents of Djoser. Alternatively, some have considered Sanakht to be Djoser's elder brother. Presently, the dominant theory is that Sanakht's reign dates to the later Third Dynasty, after Djoser. Egyptologists Toby Wilkinson, Stephan Seidlmayer, Kenneth Kitchen and Rainer Stadelmann equate Sanakht with "Nebka", a name appearing in Ramesside king lists. In support of this theory is a clay seal fragment on which the lower part of a cartouche appears. In this cartouche Wilkinson, Seidlmayer and Stadelmann see traces of a Ka-sign, the end of the name "Nebka". Likewise, Dietrich Wildung favors equating Nebka with Sanakht, although he questions the validity of the seal as evidence given that it is too badly damaged to read the inscription within the cartouche as "Nebka" with any certainty.
