According to ''National Geographic'' it took an estimated 20,000 to 30,000 workers to build the Pyramids at Giza over a period of 80 years from about 2570 to 2490 B.C. and slaves were not used.

The main pyramids are -

The Pyramid of Khufu also known as The Great Pyramid of Giza and the Pyramid of Cheops [his Greek name] Dated around 2560 B.C.

The Pyramid of Khafre. Dated around 2520 B.C.

The Pyramid of Menkaure. Dated around 2490 B.C.

More recent research has indicated that nowhere near as many people as originally believed was involved in the construction of the pyramid. In truth, perhaps only around 5,000 were actually on the building site, although there were an equivalent number of support people. However, for the time these were immense groups which would not be matched for centuries.
