Userkare

Userkare was the second pharaoh of the Sixth Dynasty, reigning briefly, 1 to 5 years, in the late 24th to early 23rd century BC. Userkare's relation to his predecessor Teti and successor Pepi I is unknown and his reign remains enigmatic. Although he is attested in historical sources, Userkare is completely absent from the tomb of the Egyptian officials who lived during his reign. In addition, the Egyptian priest Manetho reports that Userkare's predecessor Teti was murdered. Userkare is often considered to have been a short-lived usurper. Alternatively, he may have been a regent who ruled during Teti's son's childhood who later ascended the throne as Pepi I.
