The Great Pyramid was built under the authority of the Egyptian king Khufu during the Fourth Dynasty, but the physical construction was performed by a large and organised workforce rather than by Khufu personally. The workforce included skilled stonecutters, masons, carpenters, surveyors, boat crews, hauliers, administrators, cooks, bakers, brewers and other specialists. The project therefore required a complex division of labour. Khufu provided the royal authority and resources through the state, while officials and supervisors organised the practical work. Archaeological evidence from Giza has substantially changed older popular assumptions that the pyramids were constructed primarily by masses of enslaved people under brutal compulsion.
Excavations at the Giza workers settlement have revealed substantial evidence concerning the workforce. The settlement contained structures associated with food preparation, craft production, storage and administration, and excavators found large quantities of animal bones and other remains indicating that workers were provisioned on a significant scale. The evidence is consistent with organised labour receiving food and other support. Workers were divided into groups and teams, and inscriptions found at the site include informal names for work crews. Such evidence shows that the workforce possessed an internal organisation and identity rather than being an undifferentiated mass of labourers.
The workforce probably included both permanent specialists and rotating labourers. Ancient Egyptian society possessed systems of compulsory service and labour obligations through which the state could mobilise people for public works. Agricultural workers may have been available for state labour during periods when the Nile flood restricted cultivation. This does not mean every worker was a free wage labourer in the modern sense, because ancient Egyptian labour relationships included taxation in labour, rations, dependency and other forms of obligation. It also does not justify describing the entire workforce as slaves. The social and legal categories of ancient Egyptian labour were more varied than the modern binary distinction between free employees and slaves.
Skilled specialists were indispensable. Stonecutters had to understand how different stones could be quarried and shaped, while masons had to place blocks accurately and maintain the intended geometry. Surveyors established alignments and levels. Carpenters produced tools, sledges and other wooden equipment. Boat crews transported materials by water. Administrators recorded supplies, labour and deliveries. Bakers and brewers produced staple provisions for workers. These occupations show that pyramid construction was effectively a large industrial and logistical enterprise requiring many people whose work was not directly visible in the finished stone structure.
The highest levels of administration were associated with royal officials. Khufus reign included senior administrators responsible for managing the resources needed for major projects. The precise identity of the principal architect remains uncertain. The later tradition connecting pyramid building with a single genius architect does not accurately describe the available evidence. Imhotep is sometimes incorrectly identified as the architect of the Great Pyramid, but Imhotep was associated with Djosers Step Pyramid at Saqqara more than a century earlier. The Great Pyramid therefore should not be attributed to Imhotep.
Ancient inscriptions provide additional evidence about construction organisation. Quarry marks inside parts of the Great Pyramid contain names associated with Khufu and work crews. Some groups were named using expressions involving Khufu, demonstrating a connection between labour organisation and royal identity. Such marks are especially useful because they were made during construction rather than centuries later. Their informal character also provides insight into how workers organised themselves. Archaeological interpretation must nevertheless distinguish between inscriptions that directly identify a workforce and assumptions about its exact size, composition or social status.
The number of workers involved has been debated. Earlier estimates sometimes proposed enormous populations of tens or hundreds of thousands of people, but archaeological evidence has encouraged more restrained interpretations. The total workforce may have varied substantially over the approximately multi decade construction period, with different numbers required for quarrying, transport, construction and finishing. The important issue is not a single exact figure but the scale of administrative coordination required. Thousands of workers could be supported through centralised food production, housing, transport and management without requiring the presence of an impossibly large permanent population at Giza.
The people who built the Great Pyramid were therefore part of a sophisticated Old Kingdom society capable of coordinating specialist knowledge, physical labour, agricultural production and state administration. Khufu was the royal patron and the monument expressed his kingship, but the physical achievement belonged to thousands of workers and specialists whose names are mostly unknown. Archaeology has increasingly recovered evidence of their living conditions, diets, tools and organisation. This evidence is historically important because it replaces simplistic explanations with a more detailed picture of a complex workforce operating within the economic and political institutions of ancient Egypt.
