The long-term importance of Userkaf's official cult may be judged by its abandonment at the end of the Fifth Dynasty. In comparison, the official funerary cult of at least one of Userkaf's successors, Nyuserre Ini, may have lasted until the Middle Kingdom period. The mortuary temple of Userkaf must have been in ruins or dismantled by the time of the Twelfth Dynasty as indicated, for example, by a block showing the king performing a ritual found re-used as a construction material in the pyramid of Amenemhat I. Userkaf was not the only king whose mortuary temple met this fate: Nyuserre's temple was targeted even though its last priests were serving in it around this time. These facts hint at a lapse of royal interest in the state-sponsored funerary cults of Old Kingdom rulers.
