What is shepseskare?

Shepseskare was an Ancient Egyptian pharaoh from the 5th Dynasty, who ruled from approximately 2465 to 2460 BCE. Not much is known about his reign, and there is some debate among Egyptologists as to whether he was a legitimate monarch or a usurper who seized the throne briefly. Some scholars believe he may have been a son of Menkauhor Kaiu, while others suggest he was a brother or cousin. There are very few surviving records of Shepseskare, and most of what we know comes from a handful of inscriptions and tomb reliefs. Some Egyptologists believe that he may have been the pharaoh who commissioned the building of the unfinished pyramid at Abusir.
