Egypt (pronounced /ˈiːdʒɪpt/ ( listen); Arabic: مصر‎ Miṣr, pronounced [misˤɾ]  ( listen); Egyptian Arabic: Maṣr [ˈmɑsˤɾ]; Coptic: Ⲭⲏⲙⲓ, kīmi; Egyptian: Kemet), officially the Arab Republic of Egypt, is a country mainly in North Africa, with the Sinai Peninsula forming a land bridge in Western Asia. Covering an area of about 1,010,000 square kilometers (390,000 sq mi), Egypt is bordered by the Mediterranean Sea to the north, the Gaza Strip and Israel to the northeast, the Red Sea to the east, Sudan to the south and Libya to the west. Egypt is one of the most populous countries in Africa and the Middle East. The great majority of its estimated 77.4 million[1] live near the banks of the Nile River, in an area of about 40,000 square kilometers (15,000 sq mi), where the only arable agricultural land is found. The large areas of the Sahara Desert are sparsely inhabited. About half of Egypt's residents live in urban areas, with the majority spread across the densely-populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta. Egypt is famous for its ancient civilization and some of the world's most famous monuments, including the Giza pyramid complex and its Great Sphinx. The southern city of Luxor contains numerous ancient artifacts, such as the Karnak Temple and the Valley of the Kings. Egypt is widely regarded as an important political and cultural nation of the Middle East. Egypt possesses one of the most developed economies in the Middle East, with sectors such as tourism, agriculture, industry and service at almost equal rates in national production. Consequently, the Egyptian economy is rapidly developing, due in part to legislation aimed at luring investments, coupled with both internal and political stability, along with recent trade and market liberalization. One of the ancient Egyptian names of the country, Kemet (km.t), or "black land", referring to the fertile black soils of the Nile flood plains, distinct from the deshret (dšṛt), or "red land" of the desert.[4] The name is realized as kīmi and kīmə in the Coptic stage of the Egyptian language, and appeared in early Greek as Χημία (Khēmía).[5] Another name was t3-mry "land of the riverbank".[6] The names of Upper and Lower Egypt were Ta-Sheme'aw (t3-šmˁw) "sedgeland" and Ta-Mehew (t3 mḥw) "northland", respectively. Miṣr, the Arabic and modern official name of Egypt (Egyptian Arabic: Maṣr), is of Semitic origin, directly cognate with other Semitic words for Egypt such as the Hebrew מִצְרַיִם (Mitzráyim), literally meaning "the two straits" (a reference to the dynastic separation of upper and lower Egypt).[7] The word originally connoted "metropolis" or "civilization" and also means "country", or "frontier-land". The English name Egypt was borrowed from Middle French Egypte, from Latin Aegyptus, from ancient Greek Aígyptos (Αἴγυπτος), from earlier Linear B a-ku-pi-ti-yo. The adjective aigýpti-, aigýptios was borrowed into Coptic as gyptios, kyptios, and from there into Arabic as qubṭī, back formed into qubṭ, whence English Copt. The Greek forms were borrowed from Late Egyptian (Amarna) Hikuptah "Memphis", a corruption of the earlier Egyptian name Hat-ka-Ptah (ḥwt-k3-ptḥ), meaning "home of the ka (soul) of Ptah", the name of a temple to the god Ptah at Memphis.[8] Strabo attributed the word to a folk etymology in which Aígyptos (Αἴγυπτος) evolved as a compound from Aigaiou huptiōs (Aἰγαίου ὑπτίως), meaning "below the Aegean". At 1,001,450 square kilometers (386,660 sq mi),[9] Egypt is the world's 38th-largest country. In terms of land area, it is approximately the same size as all of Central America,[10] twice the size of Spain,[11] four times the size of the United Kingdom,[12] and the combined size of the US states of Texas and California.[13] Nevertheless, due to the aridity of Egypt's climate, population centres are concentrated along the narrow Nile Valley and Delta, meaning that approximately 99% of the population uses only about 5.5% of the total land area.[14] Egypt is bordered by Libya to the west, Sudan to the south, and by the Gaza Strip and Israel to the east. Egypt's important role in geopolitics stems from its strategic position: a transcontinental nation, it possesses a land bridge (the Isthmus of Suez) between Africa and Asia, which in turn is traversed by a navigable waterway (the Suez Canal) that connects the Mediterranean Sea with the Indian Ocean via the Red Sea. Apart from the Nile Valley, the majority of Egypt's landscape is a desert. The winds blowing can create sand dunes more than 100 feet (30 m) high. Egypt includes parts of the Sahara Desert and of the Libyan Desert. These deserts were referred to as the "red land" in ancient Egypt, and they protected the Kingdom of the Pharaohs from western threats. Towns and cities include Alexandria, one of the greatest ancient cities, Aswan, Asyut, Cairo, the modern Egyptian capital, El-Mahalla El-Kubra, Giza, the site of the Pyramid of Khufu, Hurghada, Luxor, Kom Ombo, Port Safaga, Port Said, Sharm el Sheikh, Suez, where the Suez Canal is located, Zagazig, and Al-Minya. Oases include Bahariya, el Dakhla, Farafra, el Kharga and Siwa. Protectorates include Ras Mohamed National Park, Zaranik Protectorate and Siwa. See Egyptian Protectorates for more information. Egypt does not receive much rainfall except in the winter months.[15] South of Cairo, rainfall averages only around 2 to 5 mm (0.1 to 0.2 in) per year and at intervals of many years. On a very thin strip of the northern coast the rainfall can be as high as 410 mm (16.1 in),[16] with most of the rainfall between October and March. Snow falls on Sinai's mountains and some of the north coastal cities such as Damietta, Baltim, Sidi Barrany, etc. and rarely in Alexandria, frost is also known in mid-Sinai and mid-Egypt. Temperatures average between 80 °F (27 °C) and 90 °F (32 °C) in summer, and up to 109 °F (43 °C) on the Red Sea coast. Temperatures average between 55 °F (13 °C) and 70 °F (21 °C) in winter. A steady wind from the northwest helps hold down the temperature near the Mediterranean coast. The Khamaseen is a wind that blows from the south in Egypt in spring, bringing sand and dust, and sometimes raises the temperature in the desert to more than 100 °F (38 °C). Every year, a predictable flooding of the Nile replenishes Egypt's soil. This gives the country consistent harvest throughout the year. Many know this event as The Gift of the Nile. The rise in sea levels due to global warming threatens Egypt's densely populated coastal strip and could have grave consequences for the country's economy, agriculture and industry. Combined with growing demographic pressures, a rise in sea levels could turn millions of Egyptians into environmental refugees by the end of the century, according to climate experts.[17] See also Population history of Egypt There is evidence of rock carvings along the Nile terraces and in the desert oases. In the 10th millennium BC, a culture of hunter-gatherers and fishers replaced a grain-grinding culture. Climate changes and/or overgrazing around 8000 BC began to desiccate the pastoral lands of Egypt, forming the Sahara. Early tribal peoples migrated to the Nile River where they developed a settled agricultural economy and more centralized society.[18] By about 6000 BC the Neolithic culture rooted in the Nile Valley.[19] During the Neolithic era, several predynastic cultures developed independently in Upper and Lower Egypt. The Badarian culture and the successor Naqada series are generally regarded as precursors to Dynastic Egyptian civilization. The earliest known Lower Egyptian site, Merimda, predates the Badarian by about seven hundred years. Contemporaneous Lower Egyptian communities coexisted with their southern counterparts for more than two thousand years, remaining somewhat culturally separate, but maintaining frequent contact through trade. The earliest known evidence of Egyptian hieroglyphic inscriptions appeared during the predynastic period on Naqada III pottery vessels, dated to about 3200 BC.[20] A unified kingdom was founded circa 3150 BC by King Menes, giving rise to a series of dynasties that ruled Egypt for the next three millennia. Egyptians subsequently referred to their unified country as tawy, meaning "two lands", and later kemet (Coptic: kīmi), the "black land", a reference to the fertile black soil deposited by the Nile river. Egyptian culture flourished during this long period and remained distinctively Egyptian in its religion, arts, language and customs. The first two ruling dynasties of a unified Egypt set the stage for the Old Kingdom period, c.2700−2200 BC., famous for its many pyramids, most notably the Third Dynasty pyramid of Djoser and the Fourth Dynasty Giza Pyramids. The First Intermediate Period ushered in a time of political upheaval for about 150 years.[21] Stronger Nile floods and stabilization of government, however, brought back renewed prosperity for the country in the Middle Kingdom c. 2040 BC, reaching a peak during the reign of Pharaoh Amenemhat III. A second period of disunity heralded the arrival of the first foreign ruling dynasty in Egypt, that of the Semitic Hyksos. The Hyksos invaders took over much of Lower Egypt around 1650 BC and founded a new capital at Avaris. They were driven out by an Upper Egyptian force led by Ahmose I, who founded the Eighteenth Dynasty and relocated the capital from Memphis to Thebes. The New Kingdom (c.1550−1070 BC) began with the Eighteenth Dynasty, marking the rise of Egypt as an international power that expanded during its greatest extension to an empire as far south as Tombos in Nubia, and included parts of the Levant in the east. This period is noted for some of the most well-known Pharaohs, including Hatshepsut, Thutmose III, Akhenaten and his wife Nefertiti, Tutankhamun and Ramesses II. The first historically attested expression of monotheism came during this period in the form of Atenism. Frequent contacts with other nations brought new ideas to the New Kingdom. The country was later invaded by Libyans, Nubians and Assyrians, but native Egyptians drove them out and regained control of their country[22].
