The Third Dynasty of ancient Egypt (Dynasty III) is the first dynasty of the Old Kingdom. Other dynasties of the Old Kingdom include the Fourth, Fifth and Sixth. The capital during the period of the Old Kingdom was at Memphis. After the turbulent last years of the Second Dynasty, which might have included civil war, Egypt came under the rule of Djoser, marking the beginning of the Third Dynasty. Both the Turin King List and the Abydos King List record five kings, while the Saqqara Tablet only records four, and Manetho records nine, many of whom did not exist or are simply the same king under multiple names. The Turin King List gives Nebka, Djoser, Djoserti, Hudjefa I, and Huni. The Abydos King List gives Nebka, Djoser, Teti, Sedjes, and Neferkare. The Saqqara Tablet gives Djoser, Djoserteti, Nebkare, and Huni. Manetho gives Necheróphes (Nebka), Tosorthrós (Djoser), Týreis (Djoserti/Sekhemkhet), Mesôchris (Sanakht, probably the same person as Nebka), Sôÿphis (also Djoser), Tósertasis (also Djoserti/Sekhemkhet), Achês (Nebtawy Nebkare; unlikely Khaba, perhaps nonexistent), Sêphuris (Qahedjet), and Kerpherês (Huni). The archaeological evidence shows that Khasekhemwy, the last ruler of the Second Dynasty, was succeeded by Djoser, who at the time was only attested by his presumed Horus name Netjerikhet. Djoser's successor was Sekhemkhet, who had the Nebty name Djeserty. The last king of the dynasty is Huni, who may be the same person as Qahedjet or, less likely, Khaba. There are three remaining Horus names of known 3rd dynasty kings: Sanakht, Khaba, and perhaps Qahedjet. One of these three, by far most likely Sanakht, went by the nebty name Nebka. Dating the Third Dynasty is similarly challenging. Shaw gives the dates as being approximately from 2686 to 2613 BCE. The Turin King List suggests a total of 75 years for the third dynasty. Baines and Malek have placed the third dynasty as spanning the years 2650–2575 BCE, while Dodson and Hilton date the dynasty to 2584–2520 BCE. It is not uncommon for these estimates to differ by more than a century.
