"Userkaf (known in ancient Greek as Usercherês, Ούσερχέρης) was an Egyptian pharaoh and the founder of the Fifth Dynasty. He reigned for seven to eight years in the early 25th century BC, during the Old Kingdom Period. He probably belonged to a branch of the Fourth Dynasty royal family, although his parentage is uncertain; he could have been the son of queen Khentkaus I. He had at least one daughter and very probably a son with his consort Neferhetepes. This son succeeded him as pharaoh Sahure.
His reign heralded the ascendancy of the cult of Ra, who effectively became Egypt´s state-god during the Fifth Dynasty. Userkaf may have been a high-priest of Ra before ascending the throne, and built a sun temple, known as the Nekhenre, between Abusir and Abu Gurab. In doing so, he instituted a tradition followed by his successors over a period of 80 years. The Nekhenre mainly functioned as a mortuary temple for the setting sun. Rites performed in the temple were primarily concerned with Ra´s creator function and his role as father of the king. Taken with the reduction in the size of the royal mortuary complex, this suggests a more concrete separation between the sun god and the king than in the preceding dynasties. After Userkaf´s death, his temple was the subject of four building phases, during which it acquired a large obelisk." - (en.wikipedia.org 30.11.2019)
