full_context: Document 1: Republic of the Congo: Bantu-speaking peoples who founded tribes during the Bantu expansions largely displaced and absorbed the earliest inhabitants of the region, the Pygmy people, about 1500 BC. The Bakongo, a Bantu ethnic group that also occupied parts of present-day Angola, Gabon, and Democratic Republic of the Congo, formed the basis for ethnic affinities and rivalries among those countries. Several Bantu kingdoms—notably those of the Kongo, the Loango, and the Teke—built trade links leading into the Congo River basin.
Document 2: Yeke Kingdom: The Yeke Kingdom (also called the "Garanganze" or "Garenganze" kingdom) of the Garanganze people in Katanga, DR Congo, was short-lived, existing from about 1856 to 1891 under one king, Msiri, but it became for a while the most powerful state in south-central Africa, controlling a territory of about half a million square kilometres. The Yeke Kingdom also controlled the only trade route across the continent from east to west, since the Kalahari Desert and Lozi Kingdom in the south and the Congo rainforest in the north blocked alternative routes. It achieved this control through natural resources and force of arms—Msiri traded Katanga's copper principally, but also slaves and ivory, for gunpowder and firearms—and by alliances through marriage. The most important alliances were with Portuguese–Angolans in the Benguela area, with Tippu Tip in the north and with Nyamwezi and Swahili traders in the east, and indirectly with the Sultan of Zanzibar who controlled the east coast traders.
Document 3: Congo River: Railways now bypass the three major falls, and much of the trade of Central Africa passes along the river, including copper, palm oil (as kernels), sugar, coffee, and cotton. The river is also potentially valuable for hydroelectric power, and the Inga Dams below Pool Malebo are first to exploit the Congo river.
Document 4: Mali: Mali lies in the torrid zone and is among the hottest countries in the world. The thermal equator, which matches the hottest spots year-round on the planet based on the mean daily annual temperature, crosses the country. Most of Mali receives negligible rainfall and droughts are very frequent. Late June to early December is the rainy season in the southernmost area. During this time, flooding of the Niger River is common, creating the Inner Niger Delta. The vast northern desert part of Mali has a hot desert climate (Köppen climate classification (BWh) with long, extremely hot summers and scarce rainfall which decreases northwards. The central area has a hot semi-arid climate (Köppen climate classification (BSh) with very high temperatures year-round, a long, intense dry season and a brief, irregular rainy season. The little southern band possesses a tropical wet and dry climate (Köppen climate classification (Aw) very high temperatures year-round with a dry season and a rainy season.
Document 5: Namibia: Typically the sub-Tropical High Pressure Belt, with frequent clear skies, provides more than 300 days of sunshine per year. It is situated at the southern edge of the tropics; the Tropic of Capricorn cuts the country about in half. The winter (June – August) is generally dry, both rainy seasons occur in summer, the small rainy season between September and November, the big one between February and April. Humidity is low, and average rainfall varies from almost zero in the coastal desert to more than 600 mm in the Caprivi Strip. Rainfall is however highly variable, and droughts are common. The last[update] bad rainy season with rainfall far below the annual average occurred in summer 2006/07.

North Ghana experiences its rainy season from March to November while South Ghana experiences its rainy season from April to mid-November. The tropical climate of Ghana is relatively mild for its latitude. The harmattan, a dry desert wind, blows in north - east Ghana from December to March, lowering the humidity and causing hotter days and cooler nights in northern part of Ghana. Average daily temperatures range from 30 ° C (86 ° F) during the day to 24 ° C (75 ° F) at night with a relative humidity between 77 percent and 85 percent. In the northern part of Ghana, there are two rainy seasons: April through June and September through November.

Document 12: Central African Republic: During the 16th and 17th centuries slave traders began to raid the region as part of the expansion of the Saharan and Nile River slave routes.

In the mid 19th century, the Bobangi people became major slave traders and sold their captives to the Americas using the Ubangi river to reach the coast.

Document 13: Nigeria: For centuries, various peoples in modern-day Nigeria traded overland with traders from North Africa. Cities in the area became regional centres in a broad network of trade routes that spanned western, central and northern Africa. In the 16th century, Spanish and Portuguese explorers were the first Europeans to begin significant, direct trade with peoples of modern-day Nigeria, at the port they named Lagos and in Calabar. Europeans traded goods with peoples at the coast; coastal trade with Europeans also marked the beginnings of the Atlantic slave trade. The port of Calabar on the historical Bight of Biafra (now commonly referred to as the Bight of Bonny) become one of the largest slave trading posts in West Africa in the era of the transatlantic slave trade. Other major slaving ports in Nigeria were located in Badagry, Lagos on the Bight of Benin and on Bonny Island on the Bight of Biafra. The majority of those enslaved and taken to these ports were captured in raids and wars. Usually the captives were taken back to the conquerors' territory as forced labour; after time, they were sometimes acculturated and absorbed into the conquerors' society. A number of slave routes were established throughout Nigeria linking the hinterland areas with the major coastal ports. Some of the more prolific slave traders were linked with the Oyo Empire in the southwest, the Aro Confederacy in the southeast and the Sokoto Caliphate in the north.
