The builders of the pyramids in ancient Egypt were skilled laborers, craftsmen, and engineers. They worked together to construct these monumental structures, primarily during the Old Kingdom period. Contrary to popular belief, they were not slaves but rather paid workers who took pride in their contributions to their society. These builders used simple tools and techniques to transport massive stone blocks from quarries to the construction sites. The most famous pyramid, the Great Pyramid of Giza, was built for the pharaoh Khufu around 2580–2560 BCE. The construction process involved careful planning and organization, showcasing the builders' advanced knowledge of mathematics and architecture.
