There are enough gaps in the knowledge of the 14th Dynasty that its absolute chronological position is debated, and can vary by as much as 75 years between authorities.
Additionally, Manfred Bietak has dated the inscriptions and monuments of Nehesy, possibly the second ruler of the 14th Dynasty, to around 1700 BC as well.
[6] Following the very short reign of Nehesy, most scholars – including Manfred Bietak and Kim Ryholt – agree that the Delta region was struck by a prolonged famine and perhaps a plague lasting until the end of the 14th Dynasty.
[1][7] The same famine may have affected the 13th Dynasty, which also exhibits instability and numerous ephemeral kings in its last 50 years of existence, from ca.
The weakened state of both kingdoms may explain, in part, why they fell rapidly to the emerging Hyksos power around 1650 BC.
However, Egyptologist Kim Ryholt notes that the Turin Canon mentions only approximately 56 kings, and does not have enough space to have recorded more than 70.
Ryholt also points to excavations at Avaris that revealed the existence of a large royal palace dating to the Second Intermediate Period.
[1] Ryholt further proposes that king Sheshi, whom he sees as a 14th Dynasty ruler, married a Nubian princess, queen Tati, to strengthen relations with the Kushite kingdom.
His conclusions are debated, however, in Ben Tor's study of the strata levels, in which seals attributed to the first five kings have been found.
