Dynasty:
Menkauhor was probably the seventh ruler of Egypt 's 5th Dynasty . According to the Turin King-list he ruled for 8 years, while Manetho credits this king with a reign of 9 years. There is, however, no contemporaneous date that can safely be attributed to Menkauhor.
History:
Menkauhor was this king's throne name, which means "Eternal are the Souls of Re". His birth name was Kalu. However, he is probably the least well attested ruler of this dynasty and can be counted among the least attested kings of any non intermediate period.
The relationship of Menkauhor with his predecessors or successors is not known. However, it is likely that he was either the brother or son of Niuserre, his predecessor. If he was Niuserre's son, it would probably have been by Niuserre's chief queen, Neput-Nebu. It is also likely that he was the father of Djedkare, who followed him to the throne. If not, he was almost certainly Djedkare's brother, with Niuserre being both king's father, or Djedkare's cousin, with Djedkare being the son of Neferefre, and Menkauhor being the son of Niuserre.
Menkauhor's reign is attested by an inscription in the Sinai and a seal from Abusir. His solar-temple, called Akhet-Re, and his pyramid are mentioned in texts from private tombs, but have not yet been identified. If the assumption that his pyramid is to be located at Dashur , or perhaps at Saqqara North, is correct, this would imply a departure from Abusir.However, some Egyptologists seem to strongly believe that his pyramid is the "Headless Pyramid", located in North Saqqara east of Teti's complex.
