Intermediate Period. Family Amenemhat IV's mother was a woman named Hetepi. Hetepi's only known attestation is an inscription on the wall of the temple of Renenutet at Medinet Madi, where she is given the title of "King's Mother", but not the titles of "King's Wife", "King's Daughter", or "King's Sister". However, this does not mean she was not a wife of Amenemhat III, as she would have dropped all her other titles by the time her son came to the throne. The relationship of Amenemhat IV to Amenemhat III is debated. Amenemhat IV was the son of Amenemhat III according to Manetho, but given the age gap of 84 years, some historians believe he was a grandson. However, Neferuptah, the only sister who was older than Sobekneferu, died before Amenemhat IV's birth, since Sobekneferu is mentioned as the heir presumptive during her father's reign; thus, she cannot be Amenemhat's mother. There is no record of another son of Amenemhat III; had he existed, he would have become the heir after Amenemhat IV's passing, not Sobekneferu. Manetho states that Amenemhat IV married his sister Sobekneferu, who is identified as a royal daughter of Amenemhat III, and who eventually became king in her own right upon the death of Amenemhat IV. However, Manetho's claim about the marriage has not been proven correct; Sobekneferu is not known to have borne the title of "King's Wife" among her other titles. Egyptologist Kim Ryholt has alternatively proposed that Amenemhat IV was a son of Hetepi's earlier husband, and was adopted by Amenemhat III, thus becoming Sobekneferu's stepbrother – which could explain the Manethonian tradition. More plausibly, Amenemhat IV may have died without a male heir, which could explain why he was succeeded by Sobekneferu. Some Egyptologists, such as Aidan Dodson and Kim Ryholt, have proposed that the first two rulers of the Thirteenth Dynasty, Sobekhotep I and Amenemhat Sonbef, might have been his sons outside the royal line. Reign Amenemhat IV first came to power as a junior coregent of his predecessor Amenemhat III, whose reign marks the apex of the Middle Kingdom period. The coregency is well attested by numerous monuments and artefacts where the names of the two kings parallel each other. The length of this coregency is uncertain; it could have lasted from one to seven years, although most scholars believe it was only two years long. The Turin Canon, a king
