The relationship of Menkauhor with his predecessors or successors is not known. 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.
His 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.
