Both Kim Ryholt and the German Egyptologist Daniel Polz concur that this pharaoh did not rule at or near the start of the 17th dynasty but rather late into the 17th dynasty just prior to the final three known kings of this dynasty (Senakhtenre, Seqenenre and Kamose.) Ryholt, however, in his 1997 reconstruction of the sequence of 17th dynasty rulers felt that a king Sobekemsaf intervened between the last Intef king and Senakhtenre. whereas in more contemporary literature, Detlef Franke rejects this view (below) and argues that there is no space for a king Sobekemsaf to intervene in the space after Nubkheperre Intef. "Contrary to Ryholt, I see no place for a king Sobekemsaf who ruled after Nubkheperra Antef. Nubkheperra Antef (c.1560 BC) is the best attested (from Abydos to Edfu, e.g. BM 631, EA 1645, coffin 6652) and most important of the three Antefs."
