Hudjefa (Ancient Egyptian for "erased" or "missing") is the pseudonym for a 2nd Dynasty pharaoh as reported on the Turin canon, a list of kings written during the reign of Ramses II.

[1] Because of the position of Hudjefa on the Turin list, he is sometimes identified with a king Sesochris reported in the Aegyptiaca, a history of Egypt written by the Egyptian priest Manetho in the 3rd century BC.

[2][5] The ancient Greek historian Manetho probably called Hudjefa I "Sésôchris" and reported that this king's body had a measurement of "five cubits in its height and three hands in its breadth".

[7] Egyptologists such as Wolfgang Helck, Nicolas Grimal, Hermann Alexander Schlögl and Francesco Tiradritti believe that king Nynetjer, the third ruler of 2nd dynasty and a predecessor of Peribsen, left a realm that was suffering from an overly complex state administration and that Nynetjer decided to split Egypt to leave it to his two sons (or, at least, two chosen successors) who would rule two separate kingdoms, in the hope that the two rulers could better administer the states.

Bell points to the inscriptions of the Palermo stone, where, in her opinion, the records of the annual Nile floods show constantly low levels during this period.

Bell had overlooked that the heights of the Nile floods in the Palermo stone inscription only takes into account the measurements of the nilometers around Memphis, but not elsewhere along the river.
