Amenemhat I
Unas' funerary cult appears to have survived during the chaotic First Intermediate Period until the Middle Kingdom. By the time of the 12th Dynasty (c. 1990–c. 1800 BC), the lector-priest Unasemsaf and his family were involved in the cult of Unas. In spite of this, Unas' funerary complex was partially dismantled and its materials reemployed for the construction of Amenemhat I and Senusret I own pyramid complexes.
