Two historical sources dating to the New Kingdom list kings belonging to the Eighth Dynasty. The earliest of the two and main historical source on the Eighth Dynasty is the Abydos king list, written during the reign of Seti I. The kings listed on the entries 40 to 56 of the Abydos king list are placed between the end of the Sixth Dynasty of the Old Kingdom period and the beginning of the Eleventh Dynasty of the Middle Kingdom. Furthermore, the names of these kings are different from those known from the Ninth and Tenth Dynasties, none of which are on the Abydos list. As a consequence, entries 40 to 56 of the list are assigned to the Seventh and Eighth Dynasties.
