First Dynasty of Egypt
Human sacrifice was part of the burials for all the pharaohs of the First Dynasty.  Servants were buried near each pharaoh's tomb, as well as animals. There are 338 people buried at the tomb of Djer.  The people and animals sacrificed, such as donkeys, would help the pharaoh in the afterlife. For unknown reasons, this practice ended with this dynasty. Later burials had shabtis (small figures like dolls) taking the place of actual people.
