EGYPT, a country forming the N.E. extremity of Africa.i In the following account a division is made into (I.) Modern Egypt, and (II.) Ancient Egypt; but the history from the earliest times is given as a separate section (III.).

Section I. includes Geography, Economics, Government, Inhabitants, Finance and Army. Section II. is subdivided into:(A) Exploration and Research; (B) The Country in Ancient Times; (C) Religion; (D) Language and Writing; (E) Art and Archaeology; (F) Chronology. Section III. is divided into three main periods:(1) Ancient History; (2) the Mahommedan Period; (~) Modern History (from Mehemet Ali).

I. MODERN EGYPT

Boundaries and Areas.Egypt is bounded N. by the Mediterranean, S. by the Anglo-Egyptian Sudan, N.E. by Palestine, E. by the Red Sea, W. by Tripoli and the Sahara. The western frontier is ill-defined. The boundary line between Tripoli and Egypt is usually taken to start from a point in the Gulf of Sollum and to run S. by E. so as to leave the oasis of Siwa to Egypt. South of Siwa the frontier, according to the Turkish firman of 1841, bends eastward, approaching the cultivated Nile-land near Wadi Halfa, i.e. the southern frontier. This southern frontier is fixed by agreement between Great Britain and Egypt at the 22 N. The N.E. frontier is an almost direct line drawn from Taba, near the head of the Gulf of Akaba, the eastern of the two gulfs into which the Red Sea divides, to the Mediterranean at Raf a ~n. 34 15 E. The peninsula of Sinai, geographically part of Asia, is thus included in the Egyptian dominions. The total area of the country is about 400,000 sq. m., or more than three times the size of the British Isles. Of this area ~-*ths is desert. Canals, roads, date plantations, &c., cover 1900 sq. m.; 2850 sq. m. are comprised in the surface of the Nile, marshes, lakes, &c. A line corresponding with the 30 N., drawn just S. of Cairo, divides the country into Lower aiid Upper Egypt, natural designations in common use, Lower Egypt being the Delta and Upper Egypt the Nile valley. By the Arabs Lower Egypt is called Er-Rif, the cultivated or fertile; Upper Egypt Es Said, the happy or fortunate. Another division of the country is into Lower, Middle and Upper Egypt, Middle Egypt in this classification being the district between Cairo and Assiut.
