The completion of the Aswan High Dam in 1971 and the resultant Lake Nasser have altered the time-honored place of the Nile River in the agriculture and ecology of Egypt. A rapidly growing population (the largest in the Arab world), limited arable land, and dependence on the Nile all continue to overtax resources and stress society.
Approximately one-third of Egyptian labor is engaged directly in farming, and many others work in the processing or trading of agricultural products. Practically all Egyptian agriculture takes place in some 25,000 km² (6 million acres) of fertile soil in the Nile Valley and Delta. Some desert lands are being developed for agriculture, including the ambitious Toshka project in Upper Egypt, but some other fertile lands in the Nile Valley and Delta are being lost to urbanization and erosion.
The Arab conquest of Egypt took place in AD 641. Although the Imperial forces resisted the Arab army under Amr ibn al-As, the majority of the civilian population, having suffered persecution for the differing Christian beliefs, were less hostile; in some cases they welcomed their new masters. Considered "People of the Book", Christians were allowed to practice their religion, under the restrictions of the Islamic Shari'a law.
In the Upper Nile Valley, around Kom Ombo and Aswan, there are about 300,000 speakers of Nubian languages, mainly Nobiin, but also Kenuzi-Dongola. The Berber languages are represented by Siwi, spoken by about 5,000 around the Siwa Oasis. There are over a million speakers of the Domari language (an Indo-Aryan language related to Romany), mostly living north of Cairo, and there are about 60,000 Greek speakers in Alexandria. Approximately 77,000 speakers of Bedawi (a Beja language) live in the Eastern Desert.
The vast majority of Egypt's population inhabit the banks of the Nile river (about 40,000 km²).Large areas of land are part of the Sahara Desert and are sparsely inhabited.
The Egyptians also expanded the practice of mummification to animals. Sacred animals central to cults, such as ibis, hawks, and cats, were mummified by the thousands.
Egypt's foreign policy operates along a non-aligned level. Factors such as population size, historical events, military strength, diplomatic expertise and a strategic geographical position give Egypt extensive political influence in the Middle East and Northern Africa, and within the Nonaligned Movement as a whole. Cairo has been a crossroads of Arab commerce and culture for millennia, and its intellectual and Islamic institutions are at the center of the region's social and cultural development.
The social origins of Islamists changed after the 1952 Revolution. In the 1940s and early 1950s, the Muslim Brotherhood had appealed primarily to urban civil servants and white and blue-collar workers. After the early 1970s, the Islamic revival attracted followers from a broad spectrum of social classes. Most activists were university students or recent graduates; they included rural-urban migrants and urban middle-class youth whose fathers were middle-level government employees or professionals. Their fields of study--medicine, engineering, military science, and pharmacy--were among the most highly competitive and prestigious disciplines in the university system. The rank-and- file members of Islamist groups have come from the middle class, the lower-middle class, and the urban working class.
Egypt also hosts two major religious institutions. Al-Azhar University, the oldest Islamic institution for higher studies (founded around 970 CE) with its corresponding mosque Al-Azhar. The head of Al-Azhar is traditionally regarded as the supreme leader of Sunni Muslims all over the world. Egypt also has a strong Christian heritage as evidenced by the existence of the Coptic Orthodox Church headed by the Patriarch of Alexandria, which claims a following of 50 million Christians worldwide (one of the famous Coptic Orthodox Churches is Saint Takla Haimanot Church in Alexandria
Coptic Orthodox Christianity is the indigenous form of Christianity that, according to tradition, the apostle Mark established in Egypt in the middle of the 1st century AD (approximately AD 60). It is the national church of Egypt. The church is one of the Oriental Orthodox churches. Its leader is the Pope of Alexandria and the Patriarch of the Holy See of Saint Mark. The current incumbent is Pope Shenouda III.
Islamists rejected Marxism and Western capitalism. Indeed, they viewed atheistic communism, Jewish Zionism, and Western "Crusader-minded" Christianity as their main enemies, which were responsible for the decadence that led to foreign domination and defeat by Zionists. They were intolerant of people who did not share their worldview. Islamists tended to be hostile toward the orthodox ulama, especially the scholars at Al Azhar who frequently criticized the Islamists' extreme religious interpretations. Islamists believed that the established social and political order had tainted the ulama, who had come to represent stumbling blocks to the new Islamic order. In addition, Islamists condemned the orthodox as "pulpit parrots" committed to a formalist practice of Islam but not to its spirit.
Mummies have been an object of intense interest in the West since archaeologists began finding them in large numbers. 19th century aristocrats would often entertain themselves by buying mummies, having them unwrapped, and holding observation sessions. These sessions destroyed several mummies, because the exposure to the air caused them to desintegrate.
