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 last quarter of the 20th century, Egyptian music was a way to communicate social and class issues. One popular modern pop singer is Amr Diab.
Traditionally, the cabinet comprises, in decreasing rank: - The Prime Minister - Ministers - Ministers of State, described as ‘junior ministers’, are assigned specific responsibilities or agencies. The portfolios of ministers of state are considerably more transient, as positions may be created and dissolved to suit specific short-term government priorities or the specific qualifications of candidates without alterations to the departmental structure, e.g. the Ministry of State for Environmental Affairs. - Ministers without portfolio, ministers who do not head specific departments and occasionally attend cabinet meetings, e.g. Minister without portfolio Omar Suleiman, the current Chief of the Egyptian Intelligence Services. - Chairmen of Departments, who head certain important departments that do not fall under the jurisdiction of any of the ministers and answer directly to the Prime Minister, e.g. The Chairman of the Suez Canal Authority. - Ministers-Delegate, who assist ministers in areas of their duties and rarely attend cabinet meeting
Popular Islam ranges from informal prayer sessions or Qur'an study to organized cults or orders. Because of the pervasive sexual segregation of Egypt's Islamic society, men and women often practice their religion in different ways. A specifically female religious custom is the zar, a ceremony for helping women placate spirits who are believed to have possessed them. Women specially trained by their mothers or other women in zar lore organize the ceremonies. A zar organizer holds weekly meetings and employs music and dance to induce ecstatic trances in possessed women. Wealthy women sometimes pay to have private zars conducted in their homes; these zars are more elaborate than public ones, last for several days, and sometimes involve efforts to exorcise spirits.
Coptic Christianity became popular in the Roman and Byzantine periods, and Egypt was indeed one of the strongest early Christian communities. Today, Christians constitute about 10% of the population.
"Egypt," wrote the Greek historian Herodotus 25 centuries ago, "is the gift of the Nile." The land's seemingly inexhaustible resources of water and soil carried by this mighty river created in the Nile Valley and Delta the world's most extensive oasis. Without the Nile, Egypt would be little more than a desert wasteland.
Arabic came to Egypt in the seventh century, and Egyptian Arabic has become the modern speech of the country. Of the many varieties of Arabic, it is the most widely spoken second dialect, probably due to the influence of Egyptian cinema throughout the Arabic-speaking world.
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.
Egypt is on good terms with all of its neighbours, and was the first Arab nation to make peace with Israel. It has a territorial dispute with Sudan over the Hala'ib Triangle
The 20th century has seen Cairo become associated with a roots revival. Musicians from across the Arab world have kept folk traditions alive, while Nubians, Saiyidis and Bedouins have established their own scenes. New varieties of folk and pop have also arisen from the Cairo hit factory
The Muslim Brotherhood's reemergence as a political force coincided with the proliferation of Islamic groups. Some of these groups espoused the violent overthrow of the government while others espoused living a devout life of rigorous observance of religious practices. It is impossible to list all the Islamic groups that emerged in the late 1970s because many of them had diffuse structures and some of the more militant groups were underground. Egypt's defeat and loss of territory in the June 1967 Six-Day War was the main cause for the growth of religiously inspired political activism. Muslims tended to view the humiliating experience as the culmination of 150 years of foreign intrusion and an affront to their vision of a true Islamic community. Islamic tradition rejected the idea of non-Muslims dominating Muslim society. Such a state of affairs discredited Muslim rulers who permitted it to persist. It was, therefore, incumbent on believers to end the domination and restore the true supremacy of Islam. As part of their Sunni creed, the most radical activists adopted jihad and committed themselves to battling unbelievers and impious Muslims. During the 1970s and 1980s, Islamists perpetrated a number of violent acts, including the assassination of Anwar Sadat in October 1981.
The Western Desert accounts for about two-thirds of the country's land area. For the most part, it is a massive sandy plateau marked by seven major depressions. One of these, Fayoum, was connected about 3,600 years ago to the Nile by canals. Today, it is an important irrigated agricultural area.
Egypt played a key role during the 1990-91 Gulf crisis. President Mubarak helped assemble the international coalition and deployed 35,000 Egyptian troops against Iraq to liberate Kuwait. The Egyptian contingent was the third largest in the coalition forces, after the U.S. and U.K. In the aftermath of the Gulf war, Egypt signed the Damascus declaration with Syria and the Gulf states to strengthen Gulf security. Egypt continues to contribute regularly to United Nations peacekeeping missions, most recently in East Timor, Sierra Leone, and Liberia.
