 Many Egyptologists accept the existence of the 14th Dynasty based on archaeological evidence and on the fact that about 50 kings are recorded in the Turin canon between the 13th Dynasty and the later Hyksos rulers.On the other hand, Redford proposed that these 50 kings constitute the genealogy of the Hyksos rulers and that the 14th Dynasty is chimerical.Based on a seriation of the scarab seals of the Second Intermediate Period available in 1900 AD, George Willoughby Fraser was able to date Sheshi's reign to "a short dynasty before the Hyksos invasion".
