Explain how egyptian commemorate the wealthy and royal dead and why?

Beginning in the New Kingdom, books of the dead were included in the grave, along with shabti statues that were believed to perform manual labor for them in the afterlife Rituals in which the deceased was magically re-animated accompanied burials. After burial, living relatives were expected to occasionally bring food to the tomb and recite prayers on behalf of the deceased.
