However, the identity of the next two or three rulers is unclear: we may have both the Horus or Nebty and their birth names for these rulers; they may be entirely different individuals; or there may be legendary names here. On the left are the rulers most Egyptologists place here; on the right are the names that ultimately come from Manetho's Aegyptica:
Although Manetho states that their capital was at Tanis, the same as during the First dynasty, at least the first three kings were buried at Saqqara, suggesting that the center of power had moved to the nearby city of Memphis. Beyond this, little can be said about the events during this period; the annual records on the Palermo stone only survive for the end of the reign of Raneb and for parts of Nynetier's. One important event possibly happened during the reign of Khasekhemwy: many Egyptologists read his name ("the Two Powers are Crowned") as commemorating the union of Upper and Lower Egypts.

This is in particular the case for the Seventh and Eighth dynasties (Memphites), the Ninth and Tenth (Heracleopolites), the Eleventh (Theban -- contemporary with the Tenth), the Thirteenth (Theban) and the Fourteenth (Xoite -- in part simultaneous), the Fifteenth, and the Sixteenth (Hyksos), and the Seventeenth Dynasty (Theban -- partly contemporary with the Sixteenth.
In some cases the second element was a mere grammatical duplicate of the first, as Ament, wife of Amen (Amon), and was considered as one with it; it was then natural to identify the son with his parents, and so arose the concept of one god in three forms.
From Khafre, the second king of the fourth dynasty, to the end of the sixth dynasty, the name Re is a part of the name of almost every one of those kings, and the monuments show that during that period numerous temples were erected to the chief of the Heliopolitan Ennead in the neighbouring nomes.
