Ниусерра
Two competing hypotheses exist in Egyptology to describe the succession of events running from the death of Neferirkare Kakai, the third king of the Fifth Dynasty, to the coronation of Nyuserre Ini, the sixth ruler of the dynasty. Relying on historical sources, where Nyuserre is said to have directly succeeded Neferefre, many Egyptologists such as Jürgen von Beckerath and Hartwig Altenmüller have traditionally believed that the following succession took place: Neferirkare Kakai → Shepseskare → Neferefre → Nyuserre Ini. In this scenario, Neferefre is the father of Nyuserre, who would have become pharaoh after Neferefre's unexpected death. Neferefre would be the successor of Shepseskare, credited with seven years of reign, as indicated in Manetho's "Aegyptiaca".
