Ancient Egypt was an ancient civilization of eastern North Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. It was part of a larger complex of civilizations, the Nile Valley Civilizations, of which regions south of Egypt (in today's Sudan, Eritrea, Somalia, and Ethiopia) are a part. Egyptian civilization coalesced around 3150 BC[1] with the political unification of Upper and Lower Egypt under the first pharaoh, and it developed over the next three millennia.[2]
Its history occurred in a series of stable Kingdoms, separated by periods of relative instability known as Intermediate Periods. Ancient Egypt reached its pinnacle during the New Kingdom, after which it entered a period of slow decline. Egypt was conquered by a succession of foreign powers in this late period. The rule of the pharaohs officially ended in 31 BC when Egypt fell to the Roman Empire and became a Roman province.[3]
The success of ancient Egyptian civilization stemmed partly from its ability to adapt to the conditions of the Nile River Valley. The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which fueled social development and culture. With resources to spare, the administration sponsored mineral exploitation of the valley and surrounding desert regions, the early development of an independent writing system, the organization of collective construction and agricultural projects, trade with surrounding regions, and a military intended to defeat foreign enemies and assert Egyptian dominance. Motivating and organizing these activities was a bureaucracy of elite scribes, religious leaders, and administrators under the control of a pharaoh who ensured the cooperation and unity of the Egyptian people in the context of an elaborate system of religious beliefs.[4][5]
The many achievements of the ancient Egyptians include the quarrying, surveying and construction techniques that facilitated the building of monumental pyramids, temples, and obelisks; a system of mathematics, a practical and effective system of medicine, irrigation systems and agricultural production techniques, the first known ships,[6] Egyptian faience and glass technology, new forms of literature, and the earliest known peace treaty.[7] Egypt left a lasting legacy. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world. Its monumental ruins have inspired the imaginations of travellers and writers for centuries. A newfound respect for antiquities and excavations in the early modern period led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy, for Egypt and the world.[8]
By the late Paleolithic period the arid climate of Northern Africa became increasingly hot and dry, forcing the populations of the area to concentrate along the Nile valley, and since nomadic modern human hunter-gatherers began living in the region through the end of the Middle Pleistocene some 120 thousand years ago, the Nile has been the lifeline of Egypt.[9] The fertile floodplain of the Nile gave humans the opportunity to develop a settled agricultural economy and a more sophisticated, centralized society that became a cornerstone in the history of human civilization.[10]
In Predynastic and Early Dynastic times, the Egyptian climate was much less arid than it is today. Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates. Foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians and this is also the period during which many animals would have been first domesticated.[11]
By about 5500 BC, small tribes living in the Nile valley had developed into a series of cultures demonstrating firm control of agriculture and animal husbandry, and identifiable by their pottery and personal items, such as combs, bracelets, and beads. The largest of these early cultures in upper Egypt, the Badari, was known for its high quality ceramics, stone tools, and its use of copper.[12]
In Northern Egypt, the Badari was followed by Amratian and Gerzean cultures[13] which showed a number of technological improvements. In Gerzian times, early evidence exists of contact with Canaan and the Byblos coast.[14]
In southern Egypt, the Naqada culture, similar to the Badari, began to expand along the Nile by about 4000 BC. As early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes.[15] Over a period of about 1,000 years, the Naqada culture developed from a few small farming communities into a powerful civilization whose leaders were in complete control of the people and resources of the Nile valley.[16] Establishing a power center at Hierakonpolis, and later at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile.[17] They also traded with Nubia to the south, the oases of the western desert to the west, and the cultures of the eastern Mediterranean to the east.[17]
The Naqada culture manufactured a diverse array of material goods, reflective of the increasing power and wealth of the elite, which included painted pottery, high quality decorative stone vases, cosmetic palettes, and jewelry made of gold, lapis, and ivory. They also developed a ceramic glaze known as faience which was used well into the Roman Period to decorate cups, amulets, and figurines.[18] During the last predynastic phase, the Naqada culture began using written symbols which would eventually evolve into a full system of hieroglyphs for writing the ancient Egyptian language.[19]
The 3rd century BC Egyptian priest Manetho grouped the long line of pharaohs from Menes to his own time into 30 dynasties, a system still in use today.[20] He chose to begin his official history with the king named "Meni" (or Menes in Greek) who was then believed to have united the two kingdoms of Upper and Lower Egypt (around 3200 BC).[21] The transition to a unified state actually happened more gradually than the ancient Egyptian writers would have us believe, and there is no contemporary record of Menes. Some scholars now believe, however, that the mythical Menes may have actually been the pharaoh Narmer, who is depicted wearing royal regalia on the ceremonial Narmer Palette in a symbolic act of unification.[22]
In the Early Dynastic Period about 3150 BC, the first of the Dynastic pharaohs solidified their control over lower Egypt by establishing a capital at Memphis, from which they could control the labor force and agriculture of the fertile delta region as well as the lucrative and critical trade routes to the Levant. The increasing power and wealth of the pharaohs during the early dynastic period was reflected in their elaborate mastaba tombs and mortuary cult structures at Abydos, which were used to celebrate the deified pharaoh after his death.[23] The strong institution of kingship developed by the pharaohs served to legitimize state control over the land, labor, and resources that were essential to the survival and growth of ancient Egyptian civilization.[24]
