Africa, the second largest continent (after Asia), covering about one-fifth of the total land surface of Earth. The continent is bounded on the west by the Atlantic Ocean, on the north by the Mediterranean Sea, on the east by the Red Sea and the Indian Ocean, and on the south by the mingling waters of the Atlantic and Indian oceans. Africa’s total land area is approximately 11,724,000 square miles (30,365,000 square km), and the continent measures about 5,000 miles (8,000 km) from north to south and about 4,600 miles (7,400 km) from east to west. Its northern extremity is Al-Ghīrān Point, near Al-Abyaḍ Point (Cape Blanc), Tunisia; its southern extremity is Cape Agulhas, South Africa; its farthest point east is Xaafuun (Hafun) Point, near Cape Gwardafuy (Guardafui), Somalia; and its western extremity is Almadi Point (Pointe des Almadies), on Cape Verde (Cap Vert), Senegal. In the northeast, Africa was joined to Asia by the Sinai Peninsula until the construction of the Suez Canal. Paradoxically, the coastline of Africa —18,950 miles (30,500 km) in length—is shorter than that of Europe, because there are few inlets and few large bays or gulfs. Off the coasts of Africa a number of islands are associated with the continent. Of these Madagascar, one of the largest islands in the world, is the most significant. Other, smaller islands include the Seychelles, Socotra, and other islands to the east; the Comoros, Mauritius, Réunion, and other islands to the southeast; Ascension, St. Helena, and Tristan da Cunha to the southwest; Cape Verde, the Bijagós Islands, Bioko, and São Tomé and Príncipe to the west; and the Azores and the Madeira and Canary islands to the northwest. The continent is cut almost equally in two by the Equator, so that most of Africa lies within the tropical region, bounded on the north by the Tropic of Cancer and on the south by the Tropic of Capricorn. Because of the bulge formed by western Africa, the greater part of Africa’s territory lies north of the Equator. Africa is crossed from north to south by the prime meridian (0° longitude), which passes a short distance to the east of Accra, Ghana.
Ethiopia, country on the Horn of Africa. The country lies completely within the tropical latitudes and is relatively compact, with similar north-south and east-west dimensions. The capital is Addis Ababa (“New Flower”), located almost at the centre of the country. Ethiopia is the largest and most populated country in the Horn of Africa. With the 1993 secession of Eritrea, its former province along the Red Sea, Ethiopia became landlocked. Ethiopia is one of the world’s oldest countries, its territorial extent having varied over the millennia of its existence. In ancient times it remained centred on Aksum, an imperial capital located in the northern part of the modern state, about 100 miles (160 km) from the Red Sea coast. The present territory was consolidated during the 19th and 20th centuries as European powers encroached into Ethiopia’s historical domain. Ethiopia became prominent in modern world affairs first in 1896, when it defeated colonial Italy in the Battle of Adwa, and again in 1935–36, when it was invaded and occupied by fascist Italy. Liberation during World War II by the Allied powers set the stage for Ethiopia to play a more prominent role in world affairs. Ethiopia was among the first independent nations to sign the Charter of the United Nations, and it gave moral and material support to the decolonization of Africa and to the growth of Pan-African cooperation. These efforts culminated in the establishment of the Organization of African Unity (since 2002, the African Union) and the United Nations Economic Commission for Africa, both of which have their headquarters in Addis Ababa. Ethiopia, in the Horn of Africa, is a rugged, landlocked country split by the Great Rift Valley. With archaeological finds dating back more than 3 million years, it’s a place of ancient culture. Among its important sites are Lalibela with its rock-cut Christian churches from the 12th–13th centuries. Aksum is the ruins of an ancient city with obelisks, tombs, castles and Our Lady Mary of Zion church.
Kenya, country in East Africa famed for its scenic landscapes and vast wildlife preserves. Its Indian Ocean coast provided historically important ports by which goods from Arabian and Asian traders have entered the continent for many centuries. Along that coast, which holds some of the finest beaches in Africa, are predominantly Muslim Swahili cities such as Mombasa, a historic centre that has contributed much to the musical and culinary heritage of the country. Inland are populous highlands famed for both their tea plantations, an economic staple during the British colonial era, and their variety of animal species, including lions, elephants, cheetahs, rhinoceroses, and hippopotamuses. Kenya’s western provinces, marked by lakes and rivers, are forested, while a small portion of the north is desert and semidesert. The country’s diverse wildlife and panoramic geography draw large numbers of European and North American visitors, and tourism is an important contributor to Kenya’s economy. The capital of Kenya is Nairobi, a sprawling city that, like many other African metropolises, is a study in contrasts, with modern skyscrapers looking out over vast shantytowns in the distance, many harbouring refugees fleeing civil wars in neighbouring countries. Older neighbourhoods, some of them prosperous, tend to be ethnically mixed and well served by utilities and other amenities, while the tents and hastily assembled shacks that ring the city tend to be organized tribally and even locally, inasmuch as in some instances whole rural villages have removed themselves to the more promising city.
Tanzania, is an East African country situated just south of the Equator. Tanzania was formed as a sovereign state in 1964 through the union of the theretofore separate states of Tanganyika and Zanzibar. Mainland Tanganyika covers more than 99 percent of the combined territories’ total area. Mafia Island is administered from the mainland, while Zanzibar and Pemba islands have a separate government administration. Dodoma, since 1974 the designated official capital of Tanzania, is centrally located on the mainland. Dar es Salaam, however, remains the seat of most government administration, as well as being the largest city and port in the country. The Tanzania mainland is bounded by Uganda, Lake Victoria, and Kenya to the north, by the Indian Ocean to the east, by Mozambique, Lake Nyasa, Malawi, and Zambia to the south and southwest, and by Lake Tanganyika, Burundi, and Rwanda to the west. Except for the narrow coastal belt of the mainland and the offshore islands, most of mainland Tanzania lies above 600 feet (200 metres) in elevation. Vast stretches of plains and plateaus contrast with spectacular relief features, notably Africa’s highest mountain, Kilimanjaro (19,340 feet [5,895 metres]), and the world’s second deepest lake, Lake Tanganyika (4,710 feet [1,436 metres] deep).
