Nile Valley in the context of "Pastoral Neolithic"

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.

The Kingdom of Kush (/kʊʃ, kʌʃ/; Egyptian: 𓎡𓄿𓈙𓈉 kꜣš, Assyrian: Kûsi, in LXX Χους or Αἰθιοπία; Coptic: ⲉϭⲱϣ Ecōš; Hebrew: כּוּשׁ Kūš), also known as the Kushite Empire, or simply Kush, was an ancient kingdom in Nubia, centered along the Nile Valley in what is now northern Sudan and southern Egypt.

The region of Nubia was an early cradle of civilization, producing several complex societies that engaged in trade and industry. The city-state of Kerma emerged as the dominant political force between 2450 and 1450 BC, controlling the Nile Valley between the first and fourth cataracts, an area as large as Egypt. The Egyptians were the first to identify Kerma as "Kush" probably from the indigenous ethnonym "Kasu", over the next several centuries the two civilizations engaged in intermittent warfare, trade, and cultural exchange.

Egyptians (Arabic: مِصرِيُّون, romanized: Miṣriyyūn, IPA: [mɪsˤrɪjˈjuːn]; Egyptian Arabic: مَصرِيِّين, romanized: Maṣriyyīn, IPA: [mɑsˤɾɪjˈjiːn]; Coptic: ⲣⲉⲙⲛ̀ⲭⲏⲙⲓ, romanized: remenkhēmi) are an ethnic group native to the Nile Valley in Egypt. Egyptian identity is closely tied to geography. The population is concentrated in the Nile Valley, a small strip of cultivable land stretching from the First Cataract to the Mediterranean and enclosed by desert both to the east and to the west. This unique geography has been the basis of the development of Egyptian society since antiquity.

The daily language of the Egyptians is a continuum of the local varieties of Arabic; the most famous dialect is known as Egyptian Arabic or Masri. Additionally, a sizable minority of Egyptians living in Upper Egypt speak Sa'idi Arabic. Egyptians are predominantly adherents of Sunni Islam with a small Shia minority and a significant proportion who follow native Sufi orders. A considerable percentage of Egyptians are Coptic Christians who belong to the Coptic Orthodox Church, whose liturgical language, Coptic, is the most recent stage of the ancient Egyptian language and is still used in prayers along with Egyptian Arabic.

The Kingdom of Kerma or the Kerma culture was an early civilization centered in Kerma, Sudan. It flourished from around 2500 BC to 1500 BC in ancient Nubia. The Kerma culture was based in the southern part of Nubia, or "Upper Nubia" (in parts of present-day northern and central Sudan), and later extended its reach northward into Lower Nubia and the border of Egypt. The polity seems to have been one of a number of Nile Valley states during the Middle Kingdom of Egypt. The Kerma civilization was an ethnic melting pot, with origins tied to a complex web of cultures native to both the Sahara, and, farther south, parts of Central Africa. In the Kingdom of Kerma's latest phase, lasting from about 1700 to 1500 BC, it absorbed the Sudanese kingdom of Sai and became a sizable, populous empire rivaling Egypt. Around 1500 BC, it was absorbed into the New Kingdom of Egypt, but rebellions continued for centuries. By the eleventh century BC, the more-Egyptianized Kingdom of Kush emerged, possibly from Kerma, and regained the region's independence from Egypt.

The Halfan industry is one of the Late Epipalaeolithic industries of the Upper Nile Valley that seems to have appeared in northern Sudan c. 22.5-22.0 ka cal BP. It is one of the earliest known backed-bladelet industries in Northern Africa, dating between 22.5 and 16 ka cal BP in Nubia. The Halfan is restricted to the north of Sudan. A parallel industry discovered in Egypt, which is in all respects similar, is known as the Kubbaniyan.

It has been suggested that the Halfan was related to the Iberomaurusian industry in the Maghreb. The earliest Iberomaurusian is dated to c. 26.0-22.5 ka cal BP and it is not clear whether the Iberomaurusian or the Halfan is more ancient. The Halfan is believed to have descended from the Khormusan Culture which depended on specialized hunting, fishing, and collecting techniques for survival.

Jebel Sahaba (Arabic: جَبَل ٱلصَّحَابَة, romanized: Jabal Aṣ-Ṣaḥābah, lit. 'Mountain of the Companions'; also Site 117) is a prehistoric cemetery site in the Nile Valley (now submerged in Lake Nasser), near the northern border of Sudan with Egypt in Northeast Africa. It is associated with the Qadan culture. It was discovered in 1964 by a team led by Fred Wendorf.

Since their discovery, the skeletons of Jebel Sahaba have been continuously re-evaluated by anthropologists seeking to determine the circumstances of their death. As of the most recent study (2021), it seems most likely that the war (dating to c. 12th millennium BC) was driven by resource scarcity due to climate change. Tribes of the Qadan culture partook in a series of raids and ambushes against one another with projectile weapons - mostly light arrows, but also much heavier arrows or throwing spears.

Makuria (Old Nubian: ⲇⲱⲧⲁⲩⲟ, Dotawo; Greek: Μακουρία, romanized: Makouria; Arabic: المقرة, romanized: al-Muqurra) was a medieval Nubian kingdom in what is today northern Sudan and southern Egypt. Its capital was Dongola (Old Nubian: Tungul) in the fertile Dongola Reach, and the kingdom is sometimes known by the name of its capital.

Coming into being after the collapse of the Kingdom of Kush in the 4th century, it originally covered the Nile Valley from the 3rd cataract to somewhere south of Abu Hamed at Mograt Island. The capital of Dongola was founded around 500 and soon after, in the mid-6th century, Makuria converted to Christianity. Probably in the early 7th century Makuria annexed its northern neighbour Nobatia, now sharing a border with Byzantine Egypt.

Giza (Arabic: محافظة الجيزة Muḥāfaẓah Al Gizah) is one of the governorates of Egypt. It is in the center of the country, situated mostly on the west bank of the Nile River opposite Cairo. Its capital is the city of Giza. It includes a stretch of the left bank of the Nile Valley around Giza, as well as a relatively small portion of the east bank (such as Ghammāzah al Kubrá and El-Saf). Giza acquired a large stretch of Egypt's Western Desert, including Bahariya Oasis when the 6th of October Governorate was merged into it on 14 April 2011. The Giza Governorate is also home to the Great Sphinx and the Pyramids of Giza.
