Ниусерра
This view was challenged, most notably by Miroslav Verner in 2000 and 2001, following excavations of the Abusir necropolis, which indicated that Neferefre's purported predecessor Shepseskare most likely reigned for only a few months between Neferefre and Nyuserre Ini. Verner proposes that the royal succession was Neferirkare Kakai → Neferefre → Shepseskare → Nyuserre Ini. In support of this hypothesis is Verner's observation that Neferefre and Nyuserre were very likely full brothers, both sons of Neferirkare Kakai, There is also evidence that Neferefre was Neferirkare's eldest son and in his early twenties at the death of his father, and thus would have been likely to inherit the throne. These observations, in addition to further archaeological evidence such as the lack of a pyramid of Shepseskare and the position of Neferefre's own, convinced Verner that Neferefre directly succeeded his father, dying after a very short reign of about two years.
