Nyuserre Ini in Wikipedia
Nyuserre Ini, also spelt as Neuserre Izi or Niuserre Isi and sometimes Nyuserra (in Greek known as Rathoris), was a Pharaoh
of Egypt during the Fifth dynasty. He is frequently given a reign of 24 or 25 years and is dated from ca. 2445 BC to
2421 BC. His prenomen, Niuserre, means "Possessed of Re's Power." Niuserre was the younger son of pharaoh Neferirkare
Kakai by Queen Khentkaus II, and the brother of the short-lived king Neferefre. 
He is often thought to have succeeded his brother directly, but there is some evidence to suggest that Shepseskare reigned
between the two, albeit only for a few weeks. Possibly, the latter had attempted to restore the lineage of Sahure who might
have been his father, deposing the lineage of Neferirkare Kakai in the process, but was unsuccessful.
Niuserre's only known consort was Reptynub. A King's Daughter by the name of Khamerernebty (A) is thought to be the
daughter of Niuserre. The identity of her mother is not known. Khamerernebty (A) was married to the vizier Ptahshepses.
In Manetho's Epitome, Nyuserre is assigned a reign of 44 years but this data is considered suspect. The Turin King List
data for his reign is badly damaged although scholars have usually assumed that it was 24 years. The Danish Egyptologist
Kim Ryholt who twice analysed the Turin King-list papyrus in the 1990s, however, notes that "Niuserre's reign is damaged.
There is a distinct trace of a 10, 20 or 30, followed by a stroke after which the papyrus breaks off. Accordingly, the
possibilities are 11-14, 21-24, and 31-34 years [for Nyuserre], and not just 24 years" as is conventionally assumed.
However, since a Sed Feast scene is noted for Nyuserre from his solar temple at Abu Gurab, a reign of more than 30 years
can be suggested for this Pharaoh.
The Czech Egyptologist Miroslav Verner who has been excavating the Old Kingdom pyramids on behalf of the University of
Prague in Egypt since 1976 concurs with the view that Nyuserre had a reign in excess of 30 years. He bases his opinion here
on this king's numerous building activities in Abusir which included the
"construction of his own pyramid complex and two small complexes Lepsius no.XXIV and no.XXV for his wives,...the completion
of the unfinished funerary monuments of his direct relatives Neferirkara, Khentkhaus II and Neferefra" as well as the
completion of this king's substantial sun temple building complex at Abu Gurab. "Beautiful reliefs with the scenes of the
sed-festival from this sun temple are occasionally considered as indirect evidence of a long reign for this king.
Generally, the historical authenticity...of such reliefs is doubted since the sed-festival scenes very probably belonged in
the Old Kingdom to the standard 'Bildprogram' of the royal funerary monuments. However, in Niuserre's case, the sed-
festival scenes from Abu Ghurob [most probably reflect] the 30th jubilee of the king's ascension to the throne."
Nyuserre's burial place is a pyramid at Abusir located between those of pharaohs Sahure and Neferirkare Kakai. Its initial
height was around 52m, with a base of about 79 square meters and a slope of 52 degrees. The volume of stone was a total of
about 112,000 cubic meters. It was originally covered with fine limestone as shown by some remaining casing stones. The
burial chamber and antechamber were both lined with fine limestone as well and roofed with 3 tiers of megalithic limestone
beams 10 meters long weighing 90 tons each. His queen, Reput-Nebu, was also buried nearby. His magnificent temple of the
solar cult at Abusir is called the Joy of Re. While military campaigns to Libya and Asia are mentioned in documents of this
period, we have no specific evidence regarding the military activities of this ruler.
