9th Dynasty hypothesis

If Wahkare Khety was the founder of the 9th Dynasty, he may be identified with the hellenized king Achthoês, the founder of this dynasty according to Manetho. Manetho reports:

The first of these [kings], Achthoês, behaving more cruel than his predecessors, wrought woes for the people of all of Egypt, but afterwards he was smitten with madness and killed by a crocodile.^[1][7]

If this hypothesis is correct, Wahkare Khety may have been a Herakleopolitan prince who profited from the weakness of the Memphite rulers of the Eighth Dynasty to seize the throne of Middle and Lower Egypt around 2150 BC. This hypothesis is supported by contemporary inscriptions referring to the northern, Herakleopolitan kingdom as the House of Khety,^[8] although that only proves that the founder of the 9th Dynasty was a Khety, but not necessarily Wahkare Khety.

10th Dynasty hypothesis

Many scholars believe instead that Wahkare Khety was a king of the 10th Dynasty, identifying him with the Khety, who was the alleged author of the famous Teaching for King Merykare, thus placing him between Neferkare VIII and Merikare. In this reconstruction, Wahkare is the last Herakleopolitan king bearing the name Khety, and the cruel Achthoês founder of the 9th Dynasty is identified with Meryibre Khety, and the House of Khety must refer to him instead.

From the Instructions, it is known that Wahkare Khety, in alliance with the nomarchs of Lower Egypt, managed to repel the nomad "Asiatics" who for generations roamed in the Nile Delta. Those nomarchs, although recognizing Wahkare's authority, ruled de facto more or less independently. The expulsion of the "Asiatics" allowed the establishment of new settlements and defense structures on the northeastern borders, as well as the reprise of trades with the Levantine coast.^[9] Wahkare, however, warned Merikare not to neglect guarding these borders, as the "Asiatics" still were considered a danger.^[10]

In the south, Wahkare and the faithful nomarch of Asyut Tefibi retook the city of Thinis, previously captured by the Thebans led by Intef II; however, the troops of Herakleopolis sacked the sacred necropolis of Thinis, a serious crime which was reported by Wahkare himself. This crime caused the immediate reaction of the Thebans, who later finally captured the Thinite nomos. After those events Wahkare Khety decided to abandon this bellicose policy and begin a phase of peaceful coexistence with the southern kingdom, which endured until part of the reign of his successor Merikare, who succeeded the long reign – five decades – of Wahkare.^[11]
