The Arab World stretches across more than of
North Africa and the part of North-East Africa and South-West Asia. The eastern part of the Arab world is called the
Mashriq. Algeria, Morocco, Tunisia, Libya and Mauritania are the
Maghreb or
Maghrib. '' (Western Arab world) The term "Arab" often connotes the Arabian Peninsula, but the larger (and more populous) part of the Arab World is North Africa. Its eight million square kilometers include two of the largest countries of the African continent,
Algeria (2.4 million km2) in the center of the region and
Sudan (1.9 million km2) in the southeast. Algeria is about three-quarters the size of
India, or about one-and-a-half times the size of
Alaska, the largest state in the United States. The largest country in the Arab West Asia is
Saudi Arabia (2 million km2). At the other extreme, the smallest autonomous mainland Arab country is
Lebanon (10,452 km2), and the smallest island Arab country is
Bahrain (665 km2). Every Arab country borders a sea or ocean, with the exception of the Arab region of northern Chad, which is completely landlocked. Iraq is actually nearly landlocked, as it has only a very narrow access to the Persian Gulf.
Historical boundaries The political borders of the Arab world have wandered, leaving Arab minorities in non-Arab countries of the
Sahel and the
Horn of Africa as well as in the Middle Eastern countries of
Cyprus,
Turkey and
Iran, and also leaving non-Arab minorities in Arab countries. However, the basic geography of sea, desert and mountain provides the enduring natural boundaries for this region. 's expansion: The Arab world straddles two continents, Africa and Asia. It is mainly oriented along an east–west axis. The West Asian Arab region comprises the
Arabian Peninsula, most of the
Levant (excluding Cyprus and Israel), most of Mesopotamia (excluding parts of Turkey and Iran) and the Persian Gulf region. The peninsula is roughly a tilted rectangle that leans back against the slope of northeast Africa, the long axis pointing toward
Turkey and
Europe. Arab North Africa comprises the entire northern third of the continent. It is surrounded by water on three sides (west, north, and east) and desert or desert scrubland on the fourth (south). In the west, it is bounded by the shores of the
Atlantic Ocean. From northeast to southwest,
Morocco,
Western Sahara (
mostly unilaterally
annexed by Morocco), and
Mauritania make up the roughly 2,000 kilometers of Arab Atlantic coastline. The southwestern sweep of the coast is gentle but substantial, such that Mauritania's capital,
Nouakchott (18°N, 16°W), is far enough west to share longitude with
Iceland (13–22°W). Nouakchott is the westernmost capital of the Arab World and the third-westernmost in Africa, and sits on the Atlantic fringe of the southwestern Sahara. Next south along the coast from Mauritania is
Senegal, whose abrupt border belies the gradient in culture from Arab to indigenous African that historically characterizes this part of
West Africa. Arab Africa's boundary to the north is again a continental boundary, the
Mediterranean Sea. This boundary begins in the west with the narrow
Strait of Gibraltar, the thirteen kilometer wide channel that connects the Mediterranean with the Atlantic to the west, and separates Morocco from
Spain to the north. East along the coast from Morocco are Algeria, Tunisia, and Libya, followed by Egypt, which forms the region's, and the continent's, northeastern corner. The coast turns briefly but sharply south at Tunisia, slopes more gently southeastward through the Libyan capital of
Tripoli, and bumps north through Libya's second city,
Benghazi, before turning straight east again through Egypt's second city,
Alexandria, at the mouth of the Nile. Along with the spine of
Italy to its north, Tunisia marks the junction of western and eastern Mediterranean, and a cultural transition as well: west of Egypt begins the region of the Arab World known as the
Maghreb include (Libya, Tunisia, Algeria, Morocco and Mauritania). Historically the 4,000-kilometer Mediterranean boundary has fluttered. Population centers north of it in
Europe have invited contact and Arab exploration—mostly friendly, though sometimes not. Islands and peninsulas near the Arab coast have changed hands. The islands of
Sicily and
Malta lie just a hundred kilometers east of the Tunisian city of
Carthage, which has been a point of contact with Europe since its founding in the first millennium BCE; both Sicily and Malta at times have been part of the Arab World. Just across the Strait of Gibraltar from Morocco, regions of the Iberian peninsula were part of the Arab World throughout the
Middle Ages, extending the northern boundary at times to the foothills of the
Pyrenees and leaving a substantial mark on local and wider European and Western culture. The northern boundary of the African Arab world has also fluttered briefly in the other direction, first through the
Crusades and later through the imperial involvement of
France,
Britain,
Spain, and
Italy. Another visitor from northern shores,
Turkey, controlled the east of the region for centuries, though not as a colonizer. Spain still maintains two small enclaves,
Ceuta and
Melilla (called "Morocco Espanol"), along the otherwise Moroccan coast. Overall this wave has ebbed, though like the Arab expansion north it has left its mark. The proximity of North Africa to Europe has always encouraged interaction, and this continues with Arab immigration to Europe and European interest in the Arab countries today. However, population centers and the physical fact of the sea keeps this boundary of the Arab World settled on the Mediterranean coastline. To the east, the
Red Sea defines the boundary between
Africa and
Asia, and thus also between Arab Africa and Arab West Asia. This sea is a long and narrow waterway with a northwest tilt, stretching 2,300 kilometers from
Egypt's
Sinai Peninsula southeast to the
Bab-el-Mandeb strait between
Djibouti in Africa and
Yemen in Arabia but on average just 150 kilometers wide. Though the sea is navigable along its length, historically much contact between Arab Africa and Arab West Asia has been either overland across the Sinai or by sea across the Mediterranean or the narrow Bab al Mendeb strait. From northwest to southeast, Egypt, Sudan, and Eritrea form the African coastline, with Djibouti marking Bab al Mendeb's African shore. Southeast along the coast from Djibouti is Somalia, but the Somali coast soon makes a 90-degree turn and heads northeast, mirroring a bend in the coast of Yemen across the water to the north and defining the south coast of the Gulf of Aden. The Somali coast then takes a hairpin turn back southwest to complete the horn of Africa. For six months of the year the
monsoon winds blow from up equatorial Somalia, past Arabia and over the small Yemeni archipelago of
Socotra, to rain on
India. They then switch directions and blow back. The east- and especially southeast-coast boundary of Arab Africa has historically been a gateway for maritime trade and cultural exchange with both
East Africa and the subcontinent. The trade winds help explain the presence of the Comoros islands, an Arab-African country, off the coast of
Mozambique, near
Madagascar in the
Indian Ocean, the southernmost part of the Arab World. The southern boundary of Arab North Africa is the strip of scrubland known as the
Sahel that crosses the continent south of the Sahara. ==States and territories==
