[1] No contemporary attestation of Sewadjkare III survives to this day and this pharaoh is only known to us thanks to the Turin canon.

According to this king list, Sewadjkare reigned for about one year and was preceded by Merdjefare and succeeded by Nebdjefare.

According to Egyptologists Kim Ryholt and Darrell Baker, Sewadjkare III was the eleventh king of the 14th Dynasty, reigning c. 1699 BC for around one year.

[1] Ryholt's reconstruction of the early 14th dynasty is controversial however and other specialists, such as Manfred Bietak and Jürgen von Beckerath, believe that the dynasty started shortly before Nehesy c. 1710 BC rather than c. 1805 BC as proposed by Ryholt.

[3][4] Sewadjkare III should not be confused with two other pharaohs bearing the same prenomen and who also reigned during the Second Intermediate Period.
