Fourth Dynasty of Egypt in the context of "Djedefre"

The Giza pyramid complex (also called the Giza necropolis) in Egypt is home to the Great Pyramid, the pyramid of Khafre, and the pyramid of Menkaure, along with their associated pyramid complexes and the Great Sphinx. All were built during the Fourth Dynasty of the Old Kingdom of ancient Egypt, between c. 2600 – c. 2500 BC. The site also includes several temples, cemeteries, and the remains of a workers' village.

The site is at the edge of the Western Desert, approximately 9 km (5.6 mi) west of the Nile River in the city of Giza, and about 13 km (8.1 mi) southwest of the city centre of Cairo. It forms the northernmost part of the 16,000 ha (160 km; 62 sq mi) Pyramid Fields of the Memphis and its Necropolis UNESCO World Heritage Site, inscribed in 1979. The pyramid fields include the Abusir, Saqqara, and Dahshur pyramid complexes, which were all built in the vicinity of Egypt's ancient capital of Memphis. Further Old Kingdom pyramid fields were located at the sites Abu Rawash, Zawyet El Aryan, and Meidum. Most of the limestone used to build the pyramids originates from the underlying Mokattam Formation.

The Great Pyramid of Giza is the largest Egyptian pyramid. It served as the tomb of pharaoh Khufu ("Cheops"), who ruled during the Fourth Dynasty of the Old Kingdom. Built c. 2600 BC over a period of about 26 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the UNESCO World Heritage Site "Memphis and its Necropolis". It is situated at the northeastern end of the line of the three main pyramids at Giza.

Initially standing at 146.6 metres (481 feet), the Great Pyramid was the world's tallest human-made structure for more than 3,800 years. Over time, most of the smooth white limestone casing was removed, which lowered the pyramid's height to the current 138.5 metres (454.4 ft); what is seen today is the underlying core structure. The base was measured to be about 230.3 metres (755.6 ft) square, giving a volume of roughly 2.6 million cubic metres (92 million cubic feet), which includes an internal hillock. The dimensions of the pyramid were 280 royal cubits (146.7 m; 481.4 ft) high, a base length of 440 cubits (230.6 m; 756.4 ft), with a seked of ⁠5+1/2⁠ palms (a slope of 51°50'40").

In ancient Egyptian history, the Old Kingdom is the period spanning c. 2700–2200 BC. It is also known as the "Age of the Pyramids" or the "Age of the Pyramid Builders", as it encompasses the reigns of the great pyramid-builders of the Fourth Dynasty, such as King Sneferu, under whom the art of pyramid-building was perfected, and the kings Khufu, Khafre and Menkaure, who commissioned the construction of the pyramids at Giza. Egypt attained its first sustained peak of civilization during the Old Kingdom, the first of three so-called "Kingdom" periods (followed by the Middle Kingdom and New Kingdom), which mark the high points of civilization in the lower Nile Valley.

The concept of an "Old Kingdom" as one of three "golden ages" was coined in 1845 by the German Egyptologist Baron von Bunsen, and its definition evolved significantly throughout the 19th and the 20th centuries. Not only was the last king of the Early Dynastic Period related to the first two kings of the Old Kingdom, but the "capital", the royal residence, remained at Ineb-Hedj, the Egyptian name for Memphis. The basic justification for separating the two periods is the revolutionary change in architecture accompanied by the effects on Egyptian society and the economy of large-scale building projects.

Khufu or Cheops was the second pharaoh of the Fourth Dynasty of Egypt, reigning during the 26th century BC in the early Old Kingdom period. 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. Khufu is also the main character noted in the Westcar Papyrus from the 13th dynasty.

The only completely preserved portrait of the king is a small 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. Khufu's has a conflicting legacy: 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. As a result, an obscure and critical picture of Khufu's personality persists.

Khafre or Chephren (died c. 2532 BC) was an ancient Egyptian monarch who was the fourth king of the Fourth Dynasty, during the earlier half of the Old Kingdom period (c. 2700–2200 BC). He was son of the king Khufu, and succeeded his brother Djedefre to the throne.

Khafre's enormous pyramid at Giza, the Pyramid of Khafre, is surpassed only by his father's (the Great Pyramid). The Great Sphinx of Giza was also built for him, according to some egyptologists, although this remains unconfirmed. Little is known about Khafre aside from the reports of Herodotus, a Greek historian who wrote 2,000 years later.

Menkaure or Menkaura (Egyptian transliteration: mn-kꜣw-rꜥ; c. 2550 BC - c. 2503 BC) was a king of the Fourth Dynasty of Egypt during the Old Kingdom. He is well known under his Hellenized names Mykerinos (Ancient Greek: Μυκερῖνος, romanized: Mukerînos by Herodotus), in turn Latinized as Mycerinus, and Menkheres (Μεγχέρης, Menkhérēs by Manetho). According to Manetho, he was the throne successor of king Bikheris, but according to archaeological evidence, he was almost certainly the successor of Khafre. Africanus (from Syncellus) reports as rulers of the fourth dynasty Sôris, Suphis I, Suphis II, Mencherês (=Menkaure), Ratoisês, Bicheris, Sebercherês, and Thamphthis in this order. Menkaure became famous for his tomb, the Pyramid of Menkaure, at Giza and his statue triads, which showed him alongside the goddess Hathor and various regional deities.

The Third Dynasty of ancient Egypt (Dynasty III) is the first dynasty of the Old Kingdom. Other dynasties of the Old Kingdom include the Fourth, Fifth and Sixth. The capital during the period of the Old Kingdom was at Memphis.

Sneferu or Soris (c. 2600 BC) was an ancient Egyptian monarch and the first pharaoh of the Fourth Dynasty of Egypt, during the earlier half of the Old Kingdom period (26th century BC). He introduced major innovations in the design and construction of pyramids, and at least three of his pyramids survive to this day.

Estimates of his reign vary, with for instance The Oxford History of Ancient Egypt suggesting a reign from around 2613 to 2589 BC, a reign of 24 years, while Rolf Krauss suggests a 30-year reign, and Rainer Stadelmann a 48-year reign.
