Films and media always show slaves working hard in the desert to build the enormous pyramids but facing a miserable death at the end of their efforts. However, the tombs found in Giza support the view that the Great Pyramics were built by free workers and not slaves, as widely believed. The tombs were beside the king's pyramid, which indicates that they were not slaves. Archaeologists say, "If they had been slaves, their tombs would not have been built beside their king's." Some tombs belonged to workers who built the pyramids of Kings Khufu and Khafre. Archaeologits found graffiti on the walls on these tombs calling themselves "friends of Khufu ", which is another sign that they were not slaves.
