Khufu

The end of Khufu's reign and Djedefre's succession

Four painted graffiti in a boat pit beside the Great Pyramid may stretch Khufu's reign to a 28th or 29th year — if the cattle count really happened every two years.

A succession with no recorded day

No exact day is known for Khufu's death, and the listed endpoint of 2526 BCE is only one proposed absolute date. The Metropolitan Museum gives the reign as about 2551–2528 BCE, while the Oxford History chronology used by the Art Institute of Chicago places it far earlier, at about 2589–2566 BCE.

What is attested is the transfer itself. Royal authority passed to Djedefre, and the funeral arrangements at Khufu's pyramid — including the deposition of boats in the southern pits — were completed in that succession context.

No day, month or season attaches to any of it. The cause of Khufu's death is not recorded in the surviving evidence, and the end of the reign is reconstructed from king lists, regnal records and the succession itself.

How long the reign actually ran

The reign's length is contested from the Egyptian side too. The Turin tradition gives Khufu 23 years, newer Western Desert and Wadi el-Jarf evidence is read as 26 or 27, and four painted graffiti recording a fourteenth cattle count in the western boat pit convert to year 28 or 29.

That last conversion assumes the count fell every two years, and Old Kingdom counting intervals were not always regular. It is an interpretation, not a settled date.

Near the end of the reign the inspector Merer kept a logbook. His crew of about forty men sailed fine Tura limestone to Akhet-Khufu, the Great Pyramid complex, averaging two or three round trips every ten days — a record of transport and work at the site, not a construction diary for the whole pyramid.

The successor written into the funeral

Several things the listing attaches to this date belong to another reign. The epithet "Son of Re" is first attested under Djedefre, which makes it evidence from the successor's reign rather than a title in use on the day Khufu's ended.

The Khufu ship is likewise not proof that a solar cult prevailed. Scholars still debate whether it was a solar barque, a funerary transport, or served both functions.

What does tie the two reigns together is written in the pits beside the pyramid: Djedefre's name appears in graffiti from the boat pits used in connection with Khufu's funeral.

What the sources leave uncertain

The listed endpoint 2526 BCE is only one proposed absolute date. The Met uses ca. 2528 BCE, while the Oxford History chronology used by the Art Institute of Chicago places Khufu much earlier, ca. 2589–2566 BCE.
The Turin tradition's 23-year reign conflicts with evidence interpreted as years 26–27 and, conditionally, 28–29.
Converting a '14th cattle count' into year 28–29 assumes the count occurred regularly every two years; Old Kingdom counting intervals were not always perfectly regular.
There is no evidence that all the developments named in the listed title—pyramid construction, Sinai activity, solar religion, succession, and royal titulary—occurred on the reign's final day.
