Old Kingdom of Egypt in the context of "Periodization of Ancient Egypt"

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.

Ancient Egypt was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150 BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of the Early Bronze Age; the Middle Kingdom of the Middle Bronze Age; or the New Kingdom of the Late Bronze Age.

The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt entered an era of slow decline. Over the course of its history, it was invaded or conquered by a number of foreign civilizations, including the Hyksos, the Kushites, the Assyrians, the Persians, and the Greeks and then the Romans. The end of ancient Egypt is variously defined as occurring with the end of the Late Period during the Wars of Alexander the Great in 332 BC or with the end of the Greek-ruled Ptolemaic Kingdom during the Roman conquest of Egypt in 30 BC. In AD 642, the Arab conquest of Egypt brought an end to the region's millennium-long Greco-Roman period.

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").

The Fourth Dynasty of ancient Egypt (notated Dynasty IV) is characterized as a "golden age" of the Old Kingdom of Egypt. Dynasty IV lasted from c. 2613 to c. 2498 BC. It was a time of peace and prosperity as well as one during which trade with other countries is officially documented.

The Fourth Dynasty heralded the height of the pyramid-building age. The peaceful rule of the Third Dynasty allowed artistic expressions to flourish. Building experiments done by King Sneferu led to the evolution of mastaba tombs into the smooth-sided pyramids like those seen on the Giza Plateau. No other period in Egyptian history equaled the accomplishments achieved during the Fourth Dynasty.

Giza (/ˈɡiːzə/; sometimes spelled Gizah, Gizeh, Geeza, Jiza; Arabic: الجيزة, romanized: al-Jīzah, pronounced [ald͡ʒiːzah], Egyptian Arabic: الجيزة el-Gīza [elˈgiːzæ]) is the third-largest city in Egypt by area after Cairo and Alexandria; and sixteenth-largest city in Africa by population. It is the capital of Giza Governorate with a total population of 4,458,135 as of 2023. It is located on the west bank of the Nile opposite central Cairo, and is a part of the Greater Cairo metropolis. Giza lies less than 30 kilometres (20 miles) north of Memphis (Men-nefer, today the village of Mit Rahina), which was the capital city of the unified Egyptian state during the reign of pharaoh Narmer, roughly 3100 BC.

Giza is most famous as the location of the Giza Plateau, the site of some of the most impressive ancient monuments in the world, including a complex of ancient Egyptian royal mortuary and sacred structures, among which are the Great Sphinx, the Great Pyramid of Giza, and a number of other large pyramids and temples and the Grand Egyptian Museum. Giza has always been a focal point in Egypt's history due to its location close to Memphis, the ancient pharaonic capital of the Old Kingdom.

The Memphite Necropolis (or Pyramid Fields) is a series of ancient Egyptian funerary complexes occupying a 30-kilometer (19 mi) stretch on the Western Desert plateau near the ancient capital of Memphis (modern day Giza).

It includes the pyramid complexes of Giza, Abusir, Saqqara and Dahshur and is recognized by UNESCO as a World Heritage Site. In addition to many of the pyramids of the Old Kingdom, the necropolis is also populated with many tombs (e.g. mastabas), temples, and funerary artifacts. However, the site’s historical importance is not limited to these features. The necropolis also includes sites such as Heit al-Ghurab. Located in the southeastern area of the Giza Plateau, the site includes the village where craftsmen working on the tombs and pyramids would have lived. As a result of its status as physical and chronological behemoth, the Memphite Necropolis stands as a valuable tool to historians in understanding changes in Egyptian funerary culture and architecture across time.

Abusir (Arabic: ابو صير  Egyptian Arabic pronunciation: [æbuˈsˤiːɾ]; Egyptian pr wsjr; Coptic: ⲃⲟⲩⲥⲓⲣⲓ busiri, "the resting place of Osiris"; Ancient Greek: Βούσιρις) is the name given to an ancient Egyptian archaeological pyramid complex comprising the ruins of 4 kings' pyramids dating to the Old Kingdom period, and is part of the Pyramid Fields of the Memphis and its Necropolis UNESCO World Heritage Site.

The pyramid complex is named after the neighbouring village of Abusir, in the markaz (county) of Badrashin, Giza. The Abusir pyramid complex is located on the Western Desert plateau at the edge of the cultivated plain, with the Giza Pyramids to its north, and Saqqara to its south, and served as one of the main elite cemeteries for the ancient Egyptian capital city of Memphis. Several other villages in northern and southern Egypt are named Abusir or Busiri.

The periodization of ancient Egypt is the use of periodization to organize the 3,000-year history of ancient Egypt. The system of 30 dynasties recorded by third-century BC Greek-speaking Egyptian priest Manetho is still in use today; however, the system of "periods" and "kingdoms" used to group the dynasties is of modern origin (19th and 20th centuries CE). The modern system consists of three "Golden Ages" (Old, Middle, and New Kingdoms), interspersed between "intermediate periods" (often, though not always, considered times of crisis or Dark Ages) and early and late periods.

The 4.2-kiloyear event (also known as the 4.2 ka event) was an aridification event (long-term drought), 4,200 years ago (4,200 years BP). It was one of the most severe climatic events of the Holocene epoch. It defines the beginning of the current Meghalayan age in the Holocene epoch.

Starting around 2200 BC, it most likely lasted the entire 22nd century BC. It has been hypothesised to have caused the collapse of the Old Kingdom in Egypt, the Akkadian Empire in Mesopotamia, and the Liangzhu culture in the lower Yangtze River area. The drought may also have initiated the collapse of the Indus Valley Civilization, with some of its population moving southeast to follow the movement of their desired habitat, as well as the migration of Indo-European-speaking people into India. Some scientists disagree with that conclusion, citing evidence that the event was not a global drought and did not happen in a clear timeline.
