This has been a hot potatoe more than once before. I agree with Merenchepri and I totally disagree with using the word "slave" as it brings on foul images of Greek, Roman and Viking slaves - who were totally owned and had no rights whatsoever. Only ignorance of how things were in AE will cause people to use it and this is very understandable. :)

But even the word "slave" as we know it, does not exist in the ancient langage. Using that word does nothing to help a reasonable knowledge of things Egyptian along.

Those who built the pyramids are nowadays rather more considered to have been farmers who worked during the time of the inundation, when anyhow their fields were under water and could not be worked. What better use of your time than to help the Father of the country to ascend to Eternity. ;)

People who worked in a "slaving capacity" shall we say? were always getting a roof over their heads and food. That went a long way. Many times they were given an allotment of land to cultivate as their own and in time, they could work more for themselves than for a "master". There are no traces of people having been bought or sold either. This is as far as I have understood the question.

Let´s use the word "worker". ;)
