Most Africans who came to North America were from West Africa and West Central Africa. (See Figure 1-1) Western Africa begins where the Sahara Desert<\/a> ends. A short erratic, rainy season supports the sparse cover of vegetation that defines the steppe like Sahel. The Sahel serves as a transition to the Sudan and classic savanna where a longer rainy season supports baobab and acacia trees sprinkled across an open vegetative landscape dominated by bushes, grasses and other herbaceous growth. Next comes another narrow transitional zone, where the savanna and forest intermingle, before the rain forest is reached. Finally, there is the coast, fringed with mangrove swamps and pounded by heavy surf (Newman 1995:104). The Sahara is likened to a sea lying north of West Africa and the Sahel to its shore. The desert and the Sahel form geographical barriers to sub-Saharan West Africa that, like of the Atlantic Ocean, contributed to the comparative isolation of the region from civilizations in Europe and the Middle East until the 15th century.<\/p>\n Knowledge of sub-Saharan West Africa is limited for the period before 800 A.D., after which the rise of Islam made Arabic records available, according to Phillip Curtin<\/a> (1990:32). Evidence from Dar-Tchitt, an archeological site in the area of Ancient Ghana, suggests agricultural expansion and intensification gave rise to walled villages of 500\u20131000 inhabitants as early as 900\u2013800 B.C. By 700 B.C. the settlement patterns changed to smaller, somewhat more numerous and unwalled villages.<\/p>\n Jenne-Jeno, a second archeological site, was first settled around 250 B.C. Located around the inland delta of the Niger river, Jenne- Jeno probably started out as a place where local farmers, herders, and fisher folk brought produce to exchange with one another. (See Figure 1-2) Over time the location became an interregional trade center. It might have been the first one in the region, but if so others soon followed and several of these became sites for a series of kingdoms and empires in the Sahel and Sudan. Eventually the region was densely populated by people who had a social organization based on kinship ties and political forms that are properly called states, and cities based on Saharan trade, at least as far south as modern day Djenne, which is between Timbuktu<\/a> and Bamako<\/a> in southern Mali<\/a>.<\/p>\n What we know comes from Berber travelers, who made their first visits to the region in the 8th century (Curtin 1990:45; Newman 1995:109\u2013110). Oral sources included African poems, praise songs, and accounts of past events usually passed on through official oral historians such as Griots, who recite the histories from Ancient Mali and Songhai often while playing stringed instruments unique to West Africa such as the Kora and Ngoni.<\/p>\n When the Portuguese first explored the West African coastline, the cultures of African societies were highly evolved and had been so for centuries. In the millennium preceding Portuguese exploration, three large centers of medieval African civilization developed sequentially along the west coast of sub-Saharan Africa. (See Figure 1-3) The first polity that is known to have gained prominence was Ancient Ghana. Between 500 AD\u20131250 AD, Ancient Ghana flourished in the southern Sahel north of the middle Niger and middle Senegal Rivers. Ancient Ghana had a civil service, strong monarchy based on a matrilineal system of inheritance, a cabinet, an army, an effective justice system and a regular source of income from trade as well as tribute from vassal kings (Boahen 1966:4\u20139).<\/p>\n","protected":false},"excerpt":{"rendered":"
