Maps of World

• Africa, particularly central Eastern Africa, is widely regarded within the scientific community to be the origin of humans and the Hominidae clade (great apes), as evidenced by the discovery of the earliest hominids and their ancestors, as well as later ones that have been dated to around seven million years ago – including Sahelanthropus tchadensis, Australopithecus africanus, A. afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens (modern human) found in Ethiopia being dated to circa 200,000 years ago.

• Africa straddles the equator and encompasses numerous climate areas; it is the only continent to stretch from the northern temperate to southern temperate zones. The African expected economic growth rate is at about 5.0% for 2010 and 5.5% in 2011.

• At the beginning of the Mesozoic Era, Africa was joined with Earth's other continents in Pangaea. Africa shared the supercontinent's relatively uniform fauna, which was dominated by theropods, prosauropods and primitive ornithischians by the close of the Triassic period. Late Triassic fossils are found through-out Africa, but are more common in the south than north. The boundary separating the Triassic and Jurassic marks the advent of an extinction event with global impact, although African strata from this time period have not been thoroughly studied.

• Early Jurassic strata are distributed in a similar fashion to Late Triassic beds, with more common outcrops in the south and less common fossil beds which are predominated by tracks to the north. As the Jurassic proceeded, larger and more iconic groups of dinosaurs like sauropods and ornithopods proliferated in Africa. Middle Jurassic strata are neither well represented nor well studied in Africa. Late Jurassic strata are also poorly represented apart from the spectacular Tendaguru fauna in Tanzania. The Late Jurassic life of Tendaguru is very similar to that found in western North America's Morrison Formation.

• By contrast to Madagascar, mainland Africa was relatively stable in position through-out the Mesozoic. Despite the stable position, major changes occurred to its relation to other landmasses as the remains of Pangea continued to break apart. By the beginning of the Late Cretaceous epoch South America had split off from Africa, completing the southern half of the Atlantic Ocean. This event had a profound effect on global climate by altering ocean currents.

• During the Cretaceous, Africa was populated by allosauroids and spinosaurids, including the largest known carnivorous dinosaurs. Titanosaurs were significant herbivores in its ancient ecosystems. Cretaceous sites are more common than Jurassic ones, but are often unable to be dated radiometrically making it difficult to know their exact ages. Paleontologist Louis Jacobs, who spent time doing field work in Malawi, says that African beds are "in need of more field work" and will prove to be a "fertile ground ... for discovery."

• Africa is considered by most paleoanthropologists to be the oldest inhabited territory on Earth, with the human species originating from the continent. During the middle of the 20th century, anthropologists discovered many fossils and evidence of human occupation perhaps as early as 7 million years ago. Fossil remains of several species of early apelike humans thought to have evolved into modern man, such as Australopithecus afarensis (radiometrically dated to approximately 3.9–3.0 million years BC), Paranthropus boisei (c. 2.3–1.4 million years BC) and Homo ergaster (c. 1.9 million–600,000 years BC) have been discovered.

• At the end of the Ice Ages, estimated to have been around 10,500 BC, the Sahara had again become a green fertile valley, and its African populations returned from the interior and coastal highlands in Sub-Saharan Africa. However, the warming and drying climate meant that by 5000 BC the Sahara region was becoming increasingly dry and hostile. The population trekked out of the Sahara region towards the Nile Valley below the Second Cataract where they made permanent or semi-permanent settlements. A major climatic recession occurred, lessening the heavy and persistent rains in Central and Eastern Africa. Since this time dry conditions have prevailed in Eastern Africa, and increasingly during the last 200 years, in Ethiopia.

• The domestication of cattle in Africa preceded agriculture and seems to have existed alongside hunter-gathering cultures. It is speculated that by 6000 BC cattle were already domesticated in North Africa. In the Sahara-Nile complex, people domesticated many animals including the donkey, and a small screw-horned goat which was common from Algeria to Nubia. In the year 4000 BC the climate of the Sahara started to become drier at an exceedingly fast pace. This climate change caused lakes and rivers to shrink significantly and caused increasing desertification. This, in turn, decreased the amount of land conducive to settlements and helped to cause migrations of farming communities to the more tropical climate of West Africa.

• By the first millennium BC ironworking had been introduced in Northern Africa and quickly spread across the Sahara into the northern parts of sub-Saharan Africa and by 500 BC metalworking began to become commonplace in West Africa. Ironworking was fully established by roughly 500 BC in many areas of East and West Africa, although other regions didn't begin ironworking until the early centuries AD. Copper objects from Egypt, North Africa, Nubia and Ethiopia dating from around 500 BC have been excavated in West Africa, suggesting that trans-saharan trade networks had been established by this date.

• European exploration of Africa began with Ancient Greeks and Romans. In 332 BC, Alexander the Great was welcomed as a liberator in Persian-occupied Egypt. He founded Alexandria in Egypt, which would become the prosperous capital of the Ptolemaic dynasty after his death. Following the conquest of North Africa's Mediterranean coastline by the Roman Empire, the area was integrated economically and culturally into the Roman system. Roman settlement occurred in modern Tunisia and elsewhere along the coast. Christianity spread across these areas from Palestine via Egypt, also passing south, beyond the borders of the Roman world into Nubia and by at least the 6th century into Ethiopia.

• In the early 7th century, the newly formed Arabian Islamic Caliphate expanded into Egypt, and then into North Africa. In a short while the local Berber elite had been integrated into Muslim Arab tribes. When the Ummayad capital Damascus fell in the 8th century, the Islamic center of the Mediterranean shifted from Syria to Qayrawan in North Africa. Islamic North Africa had become diverse, and a hub for mystics, scholars, jurists and philosophers. During the above mentioned period, Islam spread to sub-Saharan Africa, mainly through trade routes and migration.

• Pre-colonial Africa possessed perhaps as many as 10,000 different states and polities characterised by many different sorts of political organisation and rule. These included small family groups of hunter-gatherers such as the San people of southern Africa; larger, more structured groups such as the family clan groupings of the Bantu-speaking people of central and southern Africa, heavily structured clan groups in the Horn of Africa, the large Sahelian kingdoms, and autonomous city-states and kingdoms such as those of the Akan, Yoruba and Igbo people (also misspelled as Ibo) in West Africa, and the Swahili coastal trading towns of East Africa.

• By the 9th century a string of dynastic states, including the earliest Hausa states, stretched across the sub-saharan savannah from the western regions to central Sudan. The most powerful of these states were Ghana, Gao, and the Kanem-Bornu Empire. Ghana declined in the 11th century but was succeeded by the Mali Empire which consolidated much of western Sudan in the 13th century. Kanem accepted Islam in the 11th century.

• In the forested regions of the West African coast, independent kingdoms grew up with little influence from the Muslim north. The Kingdom of Nri of the Igbo was established around the 9th century and was one of the first. It is also one of the oldest Kingdom in modern day Nigeria and was ruled by the Eze Nri. The Nri kingdom is famous for its elaborate bronzes, found at the town of Igbo Ukwu. The bronzes have been dated from as far back as the 9th century.

• The Ife, historically the first of these Yoruba city-states or kingdoms, established government under a priestly oba (ruler), (oba means 'king' or 'ruler' in the Yoruba language), called the Ooni of Ife. Ife was noted as a major religious and cultural centre in Africa, and for its unique naturalistic tradition of bronze sculpture. The Ife model of government was adapted at Oyo, where its obas or kings, called the Alaafins of Oyo once controlled a large number of other Yoruba and non Yoruba city states and Kingdoms, the Fon Kingdom of Dahomey was one of the non Yoruba domains under Oyo control.

• The Almoravids were a Berber dynasty from the Sahara that spread over a wide area of northwestern Africa and the Iberian peninsula during the 11th century. The Banu Hilal and Banu Ma'qil were a collection of Arab Bedouin tribes from the Arabian peninsula who migrated westwards via Egypt between the 11th and 13th centuries. Their migration resulted in the fusion of the Arabs and Berbers, where the locals were Arabized, and Arab culture absorbed elements of the local culture, under the unifying framework of Islam.

• Following the breakup of Mali a local leader named Sonni Ali (1464–1492) founded the Songhai Empire in the region of middle Niger and the western Sudan and took control of the trans-Saharan trade. Sonni Ali seized Timbuktu in 1468 and Jenne in 1473, building his regime on trade revenues and the cooperation of Muslim merchants. His successor Askia Mohammad I (1493–1528) made Islam the official religion, built mosques, and brought Muslim scholars, including al-Maghili (d.1504), the founder of an important tradition of Sudanic African Muslim scholarship, to Gao. By the 11th century some Hausa states – such as Kano, jigawa, Katsina, and Gobir – had developed into walled towns engaging in trade, servicing caravans, and the manufacture of goods. Until the 15th century these small states were on the periphery of the major Sudanic empires of the era, paying tribute to Songhai to the west and Kanem-Borno to the east.

• Slavery had long been practiced in Africa. Between the 7th and 20th centuries, Arab slave trade (also known as slavery in the East) took 18 million slaves from Africa via trans-Saharan and Indian Ocean routes. Between the 15th and the 19th centuries (500 years), the Atlantic slave trade took an estimated 7–12 million slaves to the New World.

• In West Africa, the decline of the Atlantic slave trade in the 1820s caused dramatic economic shifts in local polities. The gradual decline of slave-trading, prompted by a lack of demand for slaves in the New World, increasing anti-slavery legislation in Europe and America, and the British Royal Navy's increasing presence off the West African coast, obliged African states to adopt new economies. Between 1808 and 1860, the British West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard.

• Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade, for example against "the usurping King of Lagos", deposed in 1851. Anti-slavery treaties were signed with over 50 African rulers. The largest powers of West Africa (the Asante Confederacy, the Kingdom of Dahomey, and the Oyo Empire) adopted different ways of adapting to the shift. Asante and Dahomey concentrated on the development of "legitimate commerce" in the form of palm oil, cocoa, timber and gold, forming the bedrock of West Africa's modern export trade. The Oyo Empire, unable to adapt, collapsed into civil wars.

• In the late 19th century, the European imperial powers engaged in a major territorial scramble and occupied most of the continent, creating many colonial territories, and leaving only two fully independent states: Ethiopia (known to Europeans as "Abyssinia"), and Liberia. Egypt and Sudan were never formally incorporated into any European colonial empire; however, after the British occupation of 1882, Egypt was effectively under British administration until 1922.

• According to the ancient Romans, Africa lay to the west of Egypt, while "Asia" was used to refer to Anatolia and lands to the east. A definite line was drawn between the two continents by the geographer Ptolemy (85–165 AD), indicating Alexandria along the Prime Meridian and making the isthmus of Suez and the Red Sea the boundary between Asia and Africa. As Europeans came to understand the real extent of the continent, the idea of Africa expanded with their knowledge.

• Geologically, Africa includes the Arabian Peninsula; the Zagros Mountains of Iran and the Anatolian Plateau of Turkey mark where the African Plate collided with Eurasia. The Afrotropic ecozone and the Saharo-Arabian desert to its north unite the region biogeographically, and the Afro-Asiatic language family unites the north linguistically.

• The climate of Africa ranges from tropical to subarctic on its highest peaks. Its northern half is primarily desert or arid, while its central and southern areas contain both savanna plains and very dense jungle (rainforest) regions. In between, there is a convergence where vegetation patterns such as sahel, and steppe dominate. Africa is the hottest continent on earth; drylands and deserts comprise 60% of the entire land surface. The record for the highest temperature recorded was set in Libya in 1992.

• Africa boasts perhaps the world's largest combination of density and "range of freedom" of wild animal populations and diversity, with wild populations of large carnivores (such as lions, hyenas, and cheetahs) and herbivores (such as buffalo, deer, elephants, camels, and giraffes) ranging freely on primarily open non-private plains. It is also home to a variety of "jungle" animals including snakes and primates and aquatic life such as crocodiles and amphibians. In addition, Africa has the largest number of megafauna species, as it was least affected by the extinction of the Pleistocene megafauna.

• There are clear signs of increased networking among African organisations and states. For example, in the civil war in the Democratic Republic of the Congo (former Zaire), rather than rich, non-African countries intervening, neighbouring African countries became involved (see also Second Congo War). Since the conflict began in 1998, the estimated death toll has reached 5 million.

• The African Union (AU) is a 53 member federation consisting of all of Africa's states except Morocco. The union was formed, with Addis Ababa, Ethiopia as its headquarters, on 26 June 2001. The union was officially established on 9 July 2002 as a successor to the Organisation of African Unity (OAU). In July 2004, the African Union's Pan-African Parliament (PAP) was relocated to Midrand, in South Africa, but the African Commission on Human and Peoples' Rights remained in Addis Ababa. There is a policy in effect to decentralize the African Federation's institutions so that they are shared by all the states.

• The African Union, not to be confused with the AU Commission, is formed by the Constitutive Act of the African Union, which aims to transform the African Economic Community, a federated commonwealth, into a state under established international conventions. The African Union has a parliamentary government, known as the African Union Government, consisting of legislative, judicial and executive organs. It is led by the African Union President and Head of State, who is also the President of the Pan African Parliament. A person becomes AU President by being elected to the PAP, and subsequently gaining majority support in the PAP. The powers and authority of the President of the African Parliament derive from the Constitutive Act and the Protocol of the Pan African Parliament, as well as the inheritance of presidential authority stipulated by African treaties and by international treaties, including those subordinating the Secretary General of the OAU Secretariat (AU Commission) to the PAP. The government of the AU consists of all-union (federal), regional, state, and municipal authorities, as well as hundreds of institutions, that together manage the day-to-day affairs of the institution.

• Political associations such as the African Union offer hope for greater co-operation and peace between the continent's many countries. Extensive human rights abuses still occur in several parts of Africa, often under the oversight of the state. Most of such violations occur for political reasons, often as a side effect of civil war. Countries where major human rights violations have been reported in recent times include the Democratic Republic of the Congo, Sierra Leone, Liberia, Sudan, Zimbabwe, and C^ote d'Ivoire.

• Although it has abundant natural resources, Africa remains the world's poorest and most underdeveloped continent, the result of a variety of causes that may include the spread of deadly diseases and viruses (notably HIV/AIDS and malaria), corrupt governments that have often committed serious human rights violations, failed central planning, high levels of illiteracy, lack of access to foreign capital, and frequent tribal and military conflict (ranging from guerrilla warfare to genocide). According to the United Nations' Human Development Report in 2003, the bottom 25 ranked nations (151st to 175th) were all African.

• Poverty, illiteracy, malnutrition and inadequate water supply and sanitation, as well as poor health, affect a large proportion of the people who reside in the African continent. In August 2008, the World Bank announced revised global poverty estimates based on a new international poverty line of $1.25 per day (versus the previous measure of $1.00). 80.5% of the Sub-Saharan Africa population was living on less than $2.50 (PPP) a day in 2005, compared with 85.7% for India.

• The new figures confirm that sub-Saharan Africa has been the least successful region of the world in reducing poverty ($1.25 per day); some 50% of the population living in poverty in 1981 (200 million people), a figure that rose to 58% in 1996 before dropping to 50% in 2005 (380 million people). The average poor person in sub-Saharan Africa is estimated to live on only 70 cents per day, and was poorer in 2003 than he or she was in 1973 indicating increasing poverty in some areas. Some of it is attributed to unsuccessful economic liberalization programs spearheaded by foreign companies and governments, but other studies and reports have cited bad domestic government policies more than external factors.

• From 1995 to 2005, Africa's rate of economic growth increased, averaging 5% in 2005. Some countries experienced still higher growth rates, notably Angola, Sudan and Equatorial Guinea, all three of which had recently begun extracting their petroleum reserves or had expanded their oil extraction capacity. The continent is believed to hold 90% of the world’s cobalt, 90% of its platinum, 50% of its gold, 98% of its chromium, 70% of its tantalite, 64% of its manganese and one-third of its uranium. The Democratic Republic of the Congo (DRC) has 70% of the world’s coltan, and most mobile phones in the world have coltan in them. The DRC also has more than 30% of the world’s diamond reserves. Guinea is the world’s largest exporter of bauxite. As the growth in Africa has been driven mainly by services and not manufacturing or agriculture, it has been growth without jobs and without reduction in poverty levels. In fact, the food security crisis of 2008 which took place on the heels of the global financial crisis has pushed back 100 million people into food insecurity.

• Africa's population has rapidly increased over the last 40 years, and consequently, it is relatively young. In some African states, half or more of the population is under 25 years of age. The total number of people in Africa grew from 221 million in 1950 to 1 billion in 2009.

• Speakers of Bantu languages (part of the Niger–Congo family) are the majority in southern, central and southeast Africa. The Bantu-speaking farmers from West Africa's inland savanna progressively expanded over most of Sub-Saharan Africa. But there are also several Nilotic groups in South Sudan and East Africa, the mixed Swahili people on the Swahili Coast, and a few remaining indigenous Khoisan ('San' or 'Bushmen') and Pygmy peoples in southern and central Africa, respectively. Bantu-speaking Africans also predominate in Gabon and Equatorial Guinea, and are found in parts of southern Cameroon. In the Kalahari Desert of Southern Africa, the distinct people known as the Bushmen (also "San", closely related to, but distinct from "Hottentots") have long been present. The San are physically distinct from other Africans and are the indigenous people of southern Africa. Pygmies are the pre-Bantu indigenous peoples of central Africa.

• The peoples of North Africa comprise two main groups: Berbers and Arabic-speaking peoples in the west, and Egyptians and Libyans in the east. The Arabs who arrived in the 7th century introduced the Arabic language and Islam to North Africa. The Semitic Phoenicians (who founded Carthage) and Hyksos, the Indo-Iranian Alans, the Indo- European Greeks, Romans and Vandals settled in North Africa as well. Berbers still make up the majority in Morocco, while they are a significant minority within Algeria. They are also present in Tunisia and Libya. The Berber-speaking Tuareg and other often-nomadic peoples are the principal inhabitants of the Saharan interior of North Africa.

• Some Ethiopian and Eritrean groups (like the Amhara and Tigrayans, collectively known as Habesha) speak languages from the Semitic branch of the Afro-Asiatic language family, while the Oromo and Somali speak languages from the Cushitic branch of Afro-Asiatic. Sudan is mostly inhabited by Nubian and Beja people, with northern Mauritania somewhat similarly structured.

• Prior to the decolonization movements of the post-World War II era, Europeans were represented in every part of Africa. Decolonisation during the 1960s and 1970s often resulted in the mass emigration of European-descended settlers out of Africa – especially from Algeria and Morocco (1.6 million pieds-noirs in North Africa), Kenya, Congo, Rhodesia, Mozambique and Angola. By the end of 1977, more than one million Portuguese were thought to have returned from Africa. Nevertheless, White Africans remain an important minority in many African states, particularly South Africa, Zimbabwe, Namibia and Réunion. The African country with the largest White African population is South Africa. The Afrikaners, the Anglo-Africans (of British origin) and the Coloureds are the largest European-descended groups in Africa today.

• European colonization also brought sizable groups of Asians, particularly people from the Indian subcontinent, to British colonies. Large Indian communities are found in South Africa, and smaller ones are present in Kenya, Tanzania, and some other southern and East African countries. The large Indian community in Uganda was expelled by the dictator Idi Amin in 1972, though many have since returned. The islands in the Indian Ocean are also populated primarily by people of Asian origin, often mixed with Africans and Europeans. The Malagasy people of Madagascar are an Austronesian people, but those along the coast are generally mixed with Bantu, Arab, Indian and European origins. Malay and Indian ancestries are also important components in the group of people known in South Africa as Cape Coloureds (people with origins in two or more races and continents). During the 20th century, small but economically important communities of Lebanese and Chinese have also developed in the larger coastal cities of West and East Africa, respectively.

• By most estimates, well over a thousand languages (UNESCO has estimated around two thousand) are spoken in Africa. Most are of African origin, though some are of European or Asian origin. Africa is the most multilingual continent in the world, and it is not rare for individuals to fluently speak not only multiple African languages, but one or more European ones as well. There are four major language families indigenous to Africa.

• Following the end of colonialism, nearly all African countries adopted official languages that originated outside the continent, although several countries also granted legal recognition to indigenous languages (such as Swahili, Yoruba, Igbo and Hausa). In numerous countries, English and French (see African French) are used for communication in the public sphere such as government, commerce, education and the media. Arabic, Portuguese, Afrikaans, Malagasy and Spanish are examples of languages that trace their origin to outside of Africa, and that are used by millions of Africans today, both in the public and private spheres. Italian is spoken by some in former Italian colonies in Africa. Prior to World War I, German was used in certain areas also.

• Some aspects of traditional African cultures have become less practiced in recent years as a result of years of neglect and suppression by colonial and post-colonial regimes. There is now a resurgence in the attempts to rediscover and revalourise African traditional cultures, under such movements as the African Renaissance, led by Thabo Mbeki, Afrocentrism, led by a group of scholars, including Molefi Asante, as well as the increasing recognition of traditional spiritualism through decriminalization of Vodou and other forms of spirituality. In recent years, traditional African culture has become synonymous with rural poverty and subsistence farming.

• Egypt has long been a cultural focus of the Arab world, while remembrance of the rhythms of sub-Saharan Africa, in particular West Africa, was transmitted through the Atlantic slave trade to modern samba, blues, jazz, reggae, hip hop, and rock. The 1950s through the 1970s saw a conglomeration of these various styles with the popularization of Afrobeat and Highlife music. Modern music of the continent includes the highly complex choral singing of southern Africa and the dance rhythms of the musical genre of soukous, dominated by the music of the Democratic Republic of Congo. Indigenous musical and dance traditions of Africa are maintained by oral traditions, and they are distinct from the music and dance styles of North Africa and Southern Africa. Arab influences are visible in North African music and dance and, in Southern Africa, Western influences are apparent due to colonisation.

• Africans profess a wide variety of religious beliefs and statistics on religious affiliation are difficult to come by since they are too sensitive a topic for governments with mixed populations. According to the World Book Encyclopedia, Islam is the largest religion in Africa, followed by Christianity. However, according to Encyclopedia Britannica, 45% of the population are Christians, 40% are Muslims and less than 15% continue to follow traditional African religions. A small number of Africans are Hindu, Baha'i, or have beliefs from the Judaic tradition. Examples of African Jews are the Beta Israel, Lemba peoples and the Abayudaya of Eastern Uganda. There is also a small minority of Africans who are non-religious.
