There is not even a suggestion of mass slavery in Egyptian history, at least not until the Greeks and Romans arrived. Egypt used a corvee labor system in which citizens (most of whom were peasant farmers) were drafted for building projects...usually during the flood period when they couldn't work on the farms anyway.
If I'm not mistaken, it was not until the 19th century that the British finally abolished the practice.
