Archeological finds in Central Africa have been discovered dating back over 100,000 years. According to Zangato and Holl, there is evidence of iron-smelting in the Central African Republic and Cameroon that may date back to 3000 to 2500 BCE. Extensive walled sites and settlements have recently been found in Zilum, Chad approximately 60 km southwest of Lake Chad dating to the first millennium BCE.
Trade and improved agricultural techniques supported more sophisticated societies, leading to the early civilizations of Sao,Kanem, Bornu, Shilluk, Baguirmi, and Wadai.Around 1000 BCE, Bantu migrants had reached the Great Lakes Region in Central Africa. Halfway through the first millennium BCE, the Bantu had also settled as far south as what is now Angola. Central Africa is a core region of the African continent which includes Burundi, the Central African Republic, Chad, theDemocratic Republic of the Congo, and Rwanda. Middle Africa (as used by the United Nations when categorising geographic subregions) is an analogous term that includes Angola, Cameroon, the Central African Republic, Chad, the Republic of the Congo, the Democratic Republic of the Congo, Equatorial Guinea, Gabon, and São Tomé and Príncipe.
The Sao civilization flourished from ca. the sixth century BCE to as late as the sixteenth century CE in northern Central Africa. The Sao lived by the Chari River south of Lake Chad in territory that later became part of Cameroon and Chad. They are the earliest people to have left clear traces of their presence in the territory of modern Cameroon. Today, several ethnic groups of northern Cameroon and southern Chad but particularly the Sara people claim descent from the civilization of the Sao. Sao artifacts show that they were skilled workers in bronze, copper, and iron. Finds include bronze sculptures and terra cotta statues of human and animal figures, coins, funerary urns, household utensils, jewelry, highly decorated pottery, and spears. The largest Sao archaeological finds have been made south of Lake Chad.
The Kanem-Bornu Empire was centered in the Chad Basin. It was known as the Kanem Empire from the 9th century CE onward and lasted as the independent kingdom of Bornu until 1900. At its height it encompassed an area covering not only much of Chad, but also parts of modern southern Libya, eastern Niger, northeastern Nigeria, northern Cameroon, parts of South Sudanand the Central African Republic. The history of the Empire is mainly known from the Royal Chronicle or Girgam discovered in 1851 by the German travellerHeinrich Barth. Kanem rose in the 8th century in the region to the north and east of Lake Chad. The Kanem empire went into decline, shrank, and in the 14th century was defeated by Bilala invaders from the Lake Fitri region.
The Kanuri people led by the Sayfuwa migrated to the west and south of the lake, where they established the Bornu Empire. By the late 16th century the Bornu empire had expanded and recaptured the parts of Kanem that had been conquered by the Bulala. Satellite states of Bornu included the Damagaram in the west and Baguirmi to the southeast of Lake Chad.
The Shilluk Kingdom was centered in South Sudan from the 15th century from along a strip of land along the western bank of White Nile, from Lake No to about 12° north latitude. The capital and royal residence was in the town of Fashoda. The kingdom was founded during the mid-fifteenth century CE by its first ruler, Nyikang. During the nineteenth century, the Shilluk Kingdom faced decline following military assaults from the Ottoman Empire and later British and Sudanese colonization inAnglo-Egyptian Sudan.
Main article: Baguirmi Kingdom
The Kingdom of Baguirmi existed as an independent state during the 16th and 17th centuries southeast of Lake Chad in what is now the country of Chad. Baguirmi emerged to the southeast of the Kanem-Bornu Empire. The kingdom's first ruler was Mbang Birni Besse. Later in his reign, the Bornu Empire conquered and made the state a tributary.
The Wadai Empire was centered on Chad and the Central African Republic from the 17th century. The Tunjur people founded the Wadai Kingdom to the east of Bornu in the 16th century. In the 17th century there was a revolt of theMaba people who established a Muslim dynasty. At first Wadai paid tribute to Bornu and Durfur, but by the 18th century Wadai was fully independent and had become an aggressor against its neighbors.
Following the Bantu Migration from West Africa, Bantu states began to develop in southern Central Africa. In the 1450s, a Luba from the royal family Ilunga Tshibinda married Lunda queen Rweej and united all Lunda peoples. Their sonmulopwe Luseeng expanded the kingdom. His son Naweej expanded the empire further and is known as the first Lunda emperor, with the title mwato yamvo (mwaant yaav,mwant yav), the Lord of Vipers. The Luba political system was retained, and conquered peoples were integrated into the system. The mwato yamvo assigned a cilool or kilolo (royal adviser) and tax collector to each state conquered.
Numerous states claimed descent from the Lunda. The Imbangala of inland Angola claimed descent from a founder, Kinguri, brother of Queen Rweej, who could not tolerate the rule of mulopweTshibunda. Kinguri became the title of kings of states founded by Queen Rweej's brother. The Luena(Lwena) and Lozi (Luyani) in Zambia also claim descent from Kinguri. During the 17th century, a Lunda chief and warrior called Mwata Kazembe set up an Eastern Lunda kingdom in the valley of the Luapula River. The Lunda's western expansion also saw claims of descent by the Yaka and thePende. The Lunda linked central Africa with the western coast trade. The kingdom of Lunda came to an end in the 19th century when it was invaded by the Chokwe, who were armed with guns.
By the 15th century CE, the farming Bakongo people (ba being the plural prefix) were unified as the Kingdom of Kongo under a ruler called the manikongo, residing in the fertile Pool Malebo area on the lower Congo River. The capital was M'banza-Kongo. With superior organization, they were able to conquer their neighbors and extract tribute. They were experts in metalwork, pottery, and weaving raffia cloth. They stimulated interregional trade via a tribute system controlled by themanikongo. Later, maize (corn) and cassava (manioc) would be introduced to the region via trade with the Portuguese at their ports at Luanda and Benguela. The maize and cassava would result in population growth in the region and other parts of Africa, replacing millet as a main staple.
By the 16th century, the manikongo held authority from the Atlantic in the west to the Kwango River in the east. Each territory was assigned a mani-mpembe (provincial governor) by the manikongo. In 1506,Afonso I (1506–1542), a Christian, took over the throne. Slave trading increased with Afonso's wars of conquest. About 1568 to 1569, the Jaga invaded Kongo, laying waste to the kingdom and forcing the manikongo into exile. In 1574, ManikongoÁlvaro I was reinstated with the help of Portuguese mercenaries. During the latter part of the 1660s, the Portuguese tried to gain control of Kongo. Manikongo António I (1661–1665), with a Kongolese army of 5,000, was destroyed by an army of Afro-Portuguese at the Battle of Mbwila. The empire dissolved into petty polities, fighting among each other for war captives to sell into slavery.
Kongo gained captives from the Kingdom of Ndongo in wars of conquest. Ndongo was ruled by the ngola. Ndongo would also engage in slave trading with the Portuguese, with São Tomé being a transit point to Brazil. The kingdom was not as welcoming as Kongo; it viewed the Portuguese with great suspicion and as an enemy. The Portuguese in the latter part of the 16th century tried to gain control of Ndongo but were defeated by the Mbundu. Ndongo experienced depopulation from slave raiding. The leaders established another state at Matamba, affiliated with Queen Nzinga, who put up a strong resistance to the Portuguese until coming to terms with them. The Portuguese settled along the coast as trade dealers, not venturing on conquest of the interior. Slavery wreaked havoc in the interior, with states initiating wars of conquest for captives. TheImbangala formed the slave-raiding state of Kasanje, a major source of slaves during the 17th and 18th centuries.
