It is estimated that around 20,000 to 30,000 workers, not slaves, were employed to build the pyramid of Giza. These workers were likely skilled laborers, farmers, and craftsmen who were paid for their work. The common misconception of slaves being used to build the pyramids is largely inaccurate.
The ancient Greek historian Herodotus who lived over 2000 years after the Great Pyramid was built by 100,000 workers. Modern archaeologists put the figure at 10-20,000.
It took 14-20 years, for 10,000 workers, a mixture of slaves and free men, to build the great pyramid of King Khufu. Perhaps the same number and time to build the second pyramid. The third Giza pyramid took about 15 years and about 5,000 workers. Smaller pyramids obviously took less time.
