They didn't really "work for free", they were slaves.
Because the majority of the workforce were slaves
pyramids
Pyramids were used as tombs to bury the Pharaoh once he died.
The slaves
no not all year if you weren't working on the pyramids you were working on the land
Both free and slave labor. The free workers did all skilled and supervisory work. The slaves did the heavy labouring jobs such as quarrying, hauling the stones and putting them in place.
When speaking about the ancient Egyptian pyramids, the common man, took time away from his farming and other activities to do the physical work in building the pyramids. This was the duty, so to speak, of the common male Egyptian.
I imagine so that people that needed to work inside the pyramids could breathe
Workers who built the pyramids in ancient Egypt were not paid with money, but rather with food, clothing, and housing. They were likely farmers who worked on the pyramids during the flood season when their fields were submerged. The work on the pyramids was considered a form of national duty or service to the pharaoh.
they made slaves work on it
Because they were given free beer
King zoser of the third dynasty thought of the pyramids!! :) ^ LIAR
