Neferirkare Kakai was the third Pharaoh of Egypt during the Fifth dynasty. His praenomen, Neferirkare, means "Beautiful is the Soul of Ra". His Horus name was Userkhau, his Golden Horus name Sekhemunebu and his Nebti name Khaiemnebty.
It was not known who Neferirkare's parents were in the past. Some Egyptologists viewed him as a son of Userkaf and Khentkaus I. This is now known to be incorrect: reliefs from Sahure's causeway show that his father was Sahure and his mother was probably Queen Meretnebty
Scenes discovered in Sahure's funerary temple, the causeway region, indicate, however, that Neferirkare may have been the son of Sahure and Queen Meretnebty. K. Sethe thought from broken records that the queen's name was Neferhanebty. This information is now known (see El Awady references above) to be incorrect. One theory holds that Neferirkare may have been known as Prince Ranefer when he was young, and had a (twin?) brother named Netjerirenre, who may have taken the throne under the name of Shepseskare.
Neferirkare (sometimes referred to as Neferirkare II because of Neferirkare Kakai) was an ancient Egyptian pharaoh of the 7th/8th Dynasty during the early First Intermediate Period (2181–2055 BC). According to the egyptologists Kim Ryholt, Jürgen von Beckerath and Darell Baker he was the 17th and final king of the combined 7th/8th Dynasty. For many scholars, this makes Neferirkare the last pharaoh of the Old Kingdom, which comes to an end with the 8th Dynasty.
Neferirkare II's name is clearly attested on the 56th entry of the Abydos King List, a king list which was redacted some 900 years after the First Intermediate Period during the reign of Seti I. The latest reconstruction of the Turin canon, another king list compiled in the Ramesside era, indicates that Neferirkare II is also attested there on column 5, line 13.
Farouk Gomaà, William C. Hayes and Baker identify Neferirkare II with the horus name Demedjibtawy (Dmḏ-ib-t3wy, "He who unifies the heart of the two lands") appearing on a single decree, the Coptos Decree R, now in the Egyptian Museum, JE 41894. The decree concerns the temple of Min at Coptos, exempting it from dues and duties. This identification is rejected by Jürgen von Beckerath.
