Egypt, officially the Arab Republic of Egypt, is a country located primarily in northeastern Africa, with the Sinai Peninsula extending into southwestern Asia.
Egypt covers approximately 1,002,000 square kilometres.
Egypt is bordered by Libya to the west, Sudan to the south, and Israel and the Gaza Strip to the northeast. It also has coastlines along the Mediterranean Sea and the Red Sea.
Egypt is divided into 27 governorates, which serve as its principal administrative divisions.
Cairo is Egypt's capital and one of the largest urban centres in Africa and the Arab world.
Arabic is Egypt's official language. Egyptian Arabic is the most widely spoken everyday variety.
Egypt's official currency is the Egyptian pound (EGP).
Egypt connects Africa and Asia through the Sinai Peninsula.
Much of Egypt consists of desert, including the Eastern Desert, Western Desert and parts of the Sahara.
Although Egypt has an enormous land area, most of its population lives near the Nile River and its delta.
According to Egypt's official geographic information, the inhabited area accounts for only about 7.8% of the country's total territory.
The Nile Valley and Nile Delta are the principal agricultural and population centres of Egypt.
Egypt's climate is predominantly arid, with a Mediterranean influence along parts of its northern coast.
Egypt's national day is celebrated on 23 July, commemorating the 1952 Egyptian Revolution.
The Nile River is one of the world's great river systems and has been central to Egyptian civilisation for thousands of years.
The Nile flows northward through Egypt before emptying into the Mediterranean Sea.
The Nile Delta is a fertile region formed where the river divides into distributaries before reaching the Mediterranean.
Ancient Egyptian agriculture depended heavily on the Nile's annual flooding, which deposited nutrient-rich sediment on surrounding farmland.
Ancient Egyptians developed systems of irrigation and water management to support agriculture in the Nile Valley.
The Nile helped connect settlements across ancient Egypt, making transportation, trade and political unification easier.
The Nile's importance is reflected in ancient Egyptian religion, literature and mythology.
Ancient Egyptian civilisation developed along the Nile thousands of years ago.
The unification of Upper and Lower Egypt is traditionally dated to around 3100 BCE, although the details and identity of the ruler responsible remain subjects of historical discussion.
Ancient Egypt developed one of the world's earliest complex state societies.
Ancient Egyptian civilisation lasted for thousands of years, passing through periods of political unification, fragmentation, foreign rule and cultural transformation.
The ancient Egyptians developed sophisticated systems of architecture, mathematics, astronomy, administration and medicine.
Ancient Egyptian society was organised around the pharaoh, who held political authority and was associated with divine kingship.
Ancient Egyptians worshipped a large and changing collection of deities, whose roles sometimes overlapped and evolved over time.
Ra, the sun god, was among the most important deities in ancient Egyptian religion.
Osiris was associated with the afterlife and resurrection, while Isis was associated with motherhood, magic and protection.
Khnum was associated with creation and was often depicted as a ram-headed deity who fashioned human beings on a potter's wheel.
Ancient Egyptian religion included beliefs about cosmic order, divine authority, death and life after death.
Egyptian pyramids were primarily royal funerary monuments associated with the burial and afterlife beliefs of kings and, in some cases, queens and other members of the royal family.
The earliest major Egyptian pyramid was the Step Pyramid of Djoser, built at Saqqara during the 27th century BCE.
Imhotep, a high-ranking official serving King Djoser, is traditionally credited with designing the Step Pyramid.
The Step Pyramid represented a major development in monumental stone architecture.
Egypt contains more than 100 identified pyramids, with the precise total depending on how incomplete and ruined structures are counted.
The Great Pyramid of Giza was built for Pharaoh Khufu during the Fourth Dynasty, around the 26th century BCE.
The Great Pyramid was originally approximately 146.6 metres tall, although erosion and the loss of its outer casing have reduced its height.
The Great Pyramid remained the tallest human-made structure in the world for thousands of years.
The pyramids at Giza were built using highly organised labour forces, skilled craftspeople and extensive systems for transporting materials.
Archaeological evidence indicates that pyramid builders received food and other provisions as compensation for their work.
Bread and beer were important components of the workers' diet. However, the claim that every worker received exactly one gallon of beer per day is not established as a universal payment rule.
Archaeologists have discovered workers' settlements and cemeteries near the Giza pyramids, providing evidence about the lives of the people involved in their construction.
The claim that millions of Egyptians died building the pyramids is unsupported. The surviving archaeological evidence does not suggest deaths on that scale.
The Great Sphinx of Giza is a monumental sculpture with a lion's body and a human head.
The Sphinx is generally associated with the reign of Pharaoh Khafre, during the Fourth Dynasty, although aspects of its precise dating and interpretation continue to be discussed.
The Great Sphinx is carved primarily from the natural limestone bedrock at Giza.
It is one of the world's largest and oldest monumental sculptures.
The Sphinx's nose is missing, but claims that Napoleon's soldiers destroyed it are false: drawings made before Napoleon's Egyptian campaign already show the nose missing.
The Sphinx's missing beard and damaged features have contributed to numerous popular stories, some of which lack historical evidence.
Ramesses II, also known as Ramesses the Great, was one of ancient Egypt's most powerful and celebrated pharaohs.
Ramesses II ruled for approximately 66 years, from around 1279 to 1213 BCE.
Ramesses II had numerous wives and children. Ancient sources and modern Egyptologists commonly associate him with more than 100 children, although exact totals are difficult to establish.
The identity of Egypt's first pharaoh is not entirely certain. Narmer is one of the earliest securely attested kings associated with the unification of Egypt.
Menes is the traditional name of a founding king in later Egyptian records and is often identified with Narmer or another early ruler.
The story that Menes ruled for 60 years before being killed by a hippopotamus is not a securely established historical fact.
Pepi II is traditionally described as one of ancient Egypt's longest-reigning kings. Some later king lists attribute an exceptionally long reign to him, but the often-repeated figure of 94 years is disputed.
Pharaohs wore elaborate crowns and headdresses, including the striped royal headdress known as the nemes.
Royal regalia helped communicate a pharaoh's status, authority and relationship with the gods.
Ancient Egyptians developed elaborate mummification techniques to preserve the bodies of certain deceased people.
Mummification was connected with beliefs about the afterlife, bodily integrity and the continued existence of the deceased.
The methods used to prepare a body varied according to historical period, social status, wealth and religious practice.
In many elite mummifications, the brain was removed through the nose or nearby openings using specialised instruments.
The liver, lungs, stomach and intestines were often removed and preserved separately, sometimes in vessels known as canopic jars.
The heart was often left inside the body because of its importance in ancient Egyptian ideas about identity, thought and judgement.
The heart was associated with the weighing of the deceased's heart against the feather of Ma'at, a symbol of truth and cosmic order.
Bodies were wrapped in linen bandages after being treated with drying agents and other substances.
The popular claim that the bandages from a single mummy could stretch for 1.6 kilometres is not a reliable universal fact; the length depended on the individual mummy and the wrapping method.
Not all ancient Egyptians were mummified in the same way. Elaborate preservation was expensive, and simpler burial practices also existed.
Ancient Egyptian religion included hundreds of named deities, with different gods becoming prominent in different regions and historical periods.
Bastet, a goddess associated with protection, home life and fertility, was frequently represented as a cat or a woman with a cat's head.
Cats were valued in ancient Egyptian society and became strongly associated with several religious traditions.
Cats were not the only animals with religious significance. Bulls, crocodiles, ibises, falcons and jackals were also associated with particular gods.
Hathor was associated with motherhood, music, joy and fertility.
Taweret, a goddess associated with childbirth and protection, was depicted with features resembling a hippopotamus.
Ancient Egyptians sometimes kept animals as pets, while other animals were raised for practical purposes or revered in religious settings.
Sacred animal cults existed at various periods, and some animals were carefully bred, mummified and buried as offerings.
Women in ancient Egypt could own property, inherit wealth, enter certain legal agreements and conduct business.
Their legal and economic opportunities varied according to period, social position and individual circumstances.
Women could hold religious offices, including roles as priestesses.
Some women attained exceptional political authority. Hatshepsut, for example, ruled as pharaoh during the 15th century BCE.
Cleopatra VII, who ruled during the first century BCE, was the last active ruler of the Ptolemaic dynasty.
Although women in ancient Egypt possessed important legal rights compared with women in many other historical societies, their lives were not identical to those of men in every respect.
Ancient Egyptian writing included hieroglyphs, a system combining signs that could represent sounds, words and concepts.
Egyptian hieroglyphic writing developed around the end of the fourth millennium BCE.
Hieroglyphs were used on monuments, tombs, religious objects and other important surfaces.
Ancient Egyptians also used cursive writing systems, including hieratic and, later, Demotic, for more practical purposes.
The ancient Egyptian civil calendar consisted of 365 days, divided into 12 months of 30 days each, plus five additional days.
Because this calendar did not include a leap day, it gradually shifted relative to the solar year.
Ancient Egyptian mathematics supported surveying, construction, accounting and the administration of agricultural land.
The ancient Egyptians used a decimal-based system of numeration, although their notation differed from modern positional numerals.
Egyptian scribes recorded measurements, inventories, taxes and other administrative information on papyrus and other materials.
Ancient Egyptian medical knowledge is documented in surviving papyri, including the Ebers Papyrus and the Edwin Smith Papyrus.
These texts describe medical conditions, treatments, injuries, diagnostic approaches and remedies.
Ancient Egyptian practitioners used a mixture of practical observation, herbal remedies, ritual practices and religious beliefs.
Some treatments used substances with properties that modern researchers continue to investigate, but this does not mean ancient Egyptians possessed modern scientific medicine.
The claim that mouldy substances used by Egyptian physicians prove they had discovered antibiotics is misleading. There is no evidence that they understood antibiotics in the modern scientific sense.
Medical specialisation existed in ancient Egypt, although the organisation of medical practitioners differed substantially from modern healthcare systems.
Beer and bread were staples of ancient Egyptian diets and were also used in religious offerings and systems of compensation.
Ancient Egyptian beer was generally different from many modern commercial beers in ingredients, preparation and flavour.
Both men and women used cosmetics, including dark eye paint commonly referred to as kohl.
Eye cosmetics had aesthetic, cultural and possibly practical purposes, but it is misleading to claim that all ancient makeup reliably protected users from the sun or healed eye disease.
Ancient Egyptians played board games, including senet, which is attested in archaeological evidence from early periods of Egyptian history.
Senet became associated with religious and funerary symbolism in some later contexts.
Ancient Egyptian games and toys provide evidence of leisure activities among different social groups.
Some ancient Egyptian households used facilities for washing and personal hygiene, but claims that modern-style toilets were universally common are exaggerated.
Ancient Egyptian diets varied by region and social status, but commonly included grains, vegetables, legumes, fish and, for some people, meat.
Heracleion, also known as Thonis, was an ancient Egyptian port city that became submerged beneath the Mediterranean Sea.
Underwater archaeological investigations have revealed remains of buildings, statues, religious objects and other material from the lost city.
Heracleion was an important port before the rise of Alexandria as a major centre of Mediterranean trade.
Alexandria was founded by Alexander the Great in 331 BCE and later became one of the most important intellectual and commercial centres of the ancient Mediterranean.
The ancient Library of Alexandria became famous as a major centre of scholarship, although details about its collections and destruction remain debated.
Ancient Egyptian archaeological sites continue to yield discoveries that improve understanding of the country's political, religious and economic history.
The Aswan High Dam is one of Egypt's most important modern engineering projects.
Construction of the Aswan High Dam began in 1960, and the dam was officially inaugurated in 1971.
The dam helps regulate Nile flows, generate hydroelectric power and support water storage for irrigation.
The creation of Lake Nasser behind the dam submerged large areas of land and threatened numerous ancient monuments.
An international UNESCO-led campaign helped relocate major monuments, including the temples of Abu Simbel, to protect them from rising water levels.
The Suez Canal connects the Mediterranean Sea with the Red Sea through Egyptian territory.
The canal is one of the world's most important maritime shipping routes because it provides a shorter connection between Europe and Asia than many alternative routes.
The Suez Canal opened to international navigation in 1869.
Egypt became a republic following the 1952 Revolution, which ended the monarchy.
Egypt's national day, 23 July, commemorates that revolution.
Hosni Mubarak served as Egypt's president from 1981 until February 2011.
The Egyptian Revolution of 2011 formed part of the wider Arab Spring protest movement.
Mubarak resigned on 11 February 2011, after weeks of mass demonstrations.
Egypt's official fact-finding commission recorded 846 deaths during the three-week uprising that led to Mubarak's resignation. (hrw.org)
Social media platforms, including Facebook and Twitter, were used by some activists to communicate, organise and circulate information during the 2011 protests.
The popular story that a father named his daughter Facebook Jamal Ibrahim in gratitude for Facebook's role in the revolution is widely repeated but should not be presented as a verified historical fact without reliable evidence.
Egypt has seven UNESCO World Heritage properties: six cultural properties and one natural property, Wadi Al-Hitan. (whc.unesco.org)
Wadi Al-Hitan, or Whale Valley, contains fossils of ancient whales that document important stages in whale evolution.
These fossils show that the ancestors of modern whales once lived in the sea and that whale evolution involved a transition from land-dwelling ancestors to fully aquatic animals.
Egypt's ancient monuments include temples, tombs, pyramids, obelisks and monumental statues spread across the Nile Valley and surrounding deserts.
The Valley of the Kings near Luxor served as a burial ground for many New Kingdom pharaohs and elite individuals.
Tutankhamun's tomb was discovered by Howard Carter's team in 1922 and became one of the most famous archaeological discoveries in modern history.
The discovery of the Rosetta Stone in 1799 helped scholars decipher Egyptian hieroglyphs.
The stone carries a decree written in three scripts: hieroglyphic, Demotic and ancient Greek.
Jean-François Champollion's work in the 1820s played a crucial role in deciphering hieroglyphic writing.
Ancient Egyptian art followed conventions that changed over time and varied by context; it was not simply an attempt to reproduce people and objects exactly as they appeared.
Egypt's archaeological heritage includes evidence of interaction with Nubia, the Levant, Greece, Rome and other neighbouring regions.
Egypt's historical importance comes not only from its pyramids but also from its contributions to state administration, architecture, writing, medicine, art and religious thought.
