What are the Pyramids and who built them?

The word, "Pharaoh," is the common title now used for the monarchs of ancient Egypt from the First Dynasty (c. 3150 BCE) until the annexation of Egypt by the Roman Empire in 30 BCE, although the term "pharaoh" was not used contemporaneously for a ruler until Merneptah, c. 1210 BCE, during the Nineteenth dynasty, "king"being the term used most frequently until the middle of the Eighteenth Dynasty. In the early dynasties, ancient Egyptian kings used to have up to three titles: the Horus, the Sedge and Bee (nswt-bjtj), and the Two Ladies or Nebty name. The Golden Horus as well as the nomen and prenomen titles were added later.

In Egyptian society, religion was central to everyday life. One of the roles of the pharaoh was as an intermediary between the deities and the people. The pharaoh thus deputised for the deities in a role that was both as civil and religious administrator. The pharaoh owned all of the land in Egypt, enacted laws, collected taxes, and defended Egypt from invaders as the commander-in-chief of the army. Religiously, the pharaoh officiated over religious ceremonies and chose the sites of new temples. The pharaoh was responsible for maintaining Maat (mꜣꜥt), or cosmic order, balance, and justice, and part of this included going to war when necessary to defend the country or attacking others when it was believed that this would contribute to Maat, such as to obtain resources.

During the early days prior to the unification of Upper and Lower Egypt, the Deshret or the "Red Crown", was a representation of the kingdom of Lower Egypt, while the Hedjet, the "White Crown", was worn by the kings of the kingdom of Upper Egypt. After the unification of both kingdoms into one united Egypt, the Pschent, the combination of both the red and white crowns was the official crown of kings.[11] With time new headdresses were introduced during different dynasties such as the Khat, Nemes, Atef, Hemhem crown, and Khepresh. At times, a combination of these headdresses or crowns worn together was depicted.

Khufu or Cheops was an ancient Egyptian monarch who was the second pharaoh of the Fourth Dynasty, in the first half of the Old Kingdom period (26th century BC). Khufu succeeded his father Sneferu as king. He is generally accepted as having commissioned the Great Pyramid of Giza, one of the Seven Wonders of the Ancient World, but many other aspects of his reign are poorly documented.

The only completely preserved portrait of the king is a three-inch high ivory figurine found in a temple ruin of a later period at Abydos in 1903. All other reliefs and statues were found in fragments, and many buildings of Khufu are lost. Everything known about Khufu comes from inscriptions in his necropolis at Giza and later documents. For example, Khufu is the main character noted in the Westcar Papyrus from the 13th dynasty.

Most documents that mention king Khufu were written by ancient Egyptian and Greek historians around 300 BC. Khufu's obituary is presented there in a conflicting way: while the king enjoyed a long-lasting cultural heritage preservation during the period of the Old Kingdom and the New Kingdom, the ancient historians Manetho, Diodorus and Herodotus hand down a very negative depiction of Khufu's character. Thanks to these documents, an obscure and critical picture of Khufu's personality persists.

Osiris is the god of fertility, agriculture, the afterlife, the dead, resurrection, life, and vegetation in ancient Egyptian religion. He was classically depicted as a green-skinned deity with a pharaoh's beard, partially mummy-wrapped at the legs, wearing a distinctive atef crown, and holding a symbolic crook and flail. He was one of the first to be associated with the mummy wrap. When his brother, Set, cut him up into pieces after killing him, Isis, his wife, found all the pieces and wrapped his body up, enabling him to return to life. Osiris was widely worshipped until the decline of ancient Egyptian religion during the rise of Christianity in the Roman Empire.

Osiris was at times considered the eldest son of the earth god Geb and the sky goddess Nut, as well as being brother and husband of Isis, and brother of Set, Nephthys, and Horus the Elder, with Horus the Younger being considered his posthumously begotten son. Through syncretism with Iah, he was also a god of the Moon.

Osiris was the judge and lord of the dead and the underworld, the "Lord of Silence" and Khenti-Amentiu, meaning "Foremost of the Westerners". In the Old Kingdom (2686 - 2181 BC) the pharaoh was considered a son of the sun god Ra who, after his death, ascended to join Ra in the sky. After the spread of the Osiris cult, however, the kings of Egypt were associated with Osiris in death – as Osiris rose from the dead, they would unite with him and inherit eternal life through imitative magic.

Through the hope of new life after death, Osiris began to be associated with the cycles in nature, in particular the sprouting of vegetation and the annual flooding of the Nile River, as well as the heliacal rising of Orion and Sirius at the start of the new year. He became the sovereign that granted all life, "He Who is Permanently Benign and Youthful".

The first evidence of the worship of Osiris is from the middle of the Fifth Dynasty of Egypt (25th century BC), although it is likely that he was worshiped much earlier; the Khenti-Amentiu epithet dates to at least the First Dynasty, and was also used as a pharaonic title. Most information available on the Osiris myth is derived from allusions in the Pyramid Texts at the end of the Fifth Dynasty, later New Kingdom source documents such as the Shabaka Stone and "The Contendings of Horus and Seth", and much later, in the narratives of Greek authors including Plutarch and Diodorus Siculus.

Some Egyptologists believe the Osiris mythos may have originated in a former living ruler - possibly a shepherd who lived in Predynastic times (5500–3100 BC) in the Nile Delta, whose beneficial rule led to him being revered as a god. The accoutrements of the shepherd, the crook and the flail - once insignia of the Delta god Andjety, with whom Osiris was associated - support this theory.

The work of quarrying, moving, setting, and sculpting the huge amount of stone used to build the pyramids might have been accomplished by several thousand skilled workers, unskilled laborers and supporting workers. Bakers, carpenters, water carriers, and others were also needed for the project. Along with the methods utilized to construct the pyramids, there is also wide speculation regarding the exact number of workers needed for a building project of this magnitude. When Greek historian Herodotus visited Giza in 450 BC, he was told by Egyptian priests that "the Great Pyramid had taken 400,000 men 20 years to build, working in three-month shifts 100,000 men at a time." Evidence from the tombs indicates that a workforce of 10,000 laborers working in three-month shifts took around 30 years to build a pyramid.

The Giza pyramid complex is surrounded by a large stone wall, outside which Mark Lehner and his team discovered a town where the pyramid workers were housed. The village is located to the southeast of the Khafre and Menkaure complexes. Among the discoveries at the workers' village are communal sleeping quarters, bakeries, breweries, and kitchens (with evidence showing that bread, beef, and fish were staples of the diet), a hospital and a cemetery (where some of the skeletons were found with signs of trauma associated with accidents on a building site). The workers' town appears to date from the middle 4th Dynasty (2520–2472 BC), after the accepted time of Khufu and completion of the Great Pyramid. According to Lehner and the AERA team:

The development of this urban complex must have been quite rapid. All of the construction probably happened in the 35 to 50 years that spanned the reigns of Khafre and Menkaure, builders of the Second and Third Giza Pyramids.

Without carbon dating, using only pottery shards, seal impressions, and stratigraphy to date the site, the team further concludes.

The picture that emerges is that of a planned settlement, some of the world's earliest urban planning, securely dated to the reigns of two Giza pyramid builders: Khafre (2520–2494 BC) and Menkaure (2490–2472 BC).
