Title: Colonisation of Africa
Content:  The history of external colonisation of Africa can be dated from ancient, medieval, or modern history, depending on how the term colonisation is defined. Ancient Greeks, Romans, Arabs and Malays all established colonies on the African continent, some of which endured centuries. In popular parlance, discussions of colonialism in Africa usually focus on the European conquests of the New Imperialism and the Scramble for Africa (1884-1914) era, followed by gradual decolonisation after WW2. The principal powers involved in the modern colonisation of Africa are Britain, France, Germany, Portugal, Spain and Italy. In nearly all African countries today, the language used in government and media is the one imposed by a recent colonial power, though most people speak their native African languages.

Importantly, the rise of the numeracy was higher in the regions which were less hierarchical and had less dependent from the slavery trade (e.g. Sine and Salum). Whereas areas with the opposite trends illustrated opposite tendencies (e.g. central and northern Senegal). Those patterns were further even more stimulated with the French colonial campaign. Britain controlled the Gambia, Sierra Leone, Ghana, and Nigeria throughout the colonial era, while France unified Senegal, Guinea, Mali, Burkina Faso, Benin, Ivory Coast, and Niger into French West Africa. Portugal founded the colony of Guinea-Bissau, while Germany claimed Togoland, but was forced to divide it between France and Britain following First World War due to the Treaty of Versailles.

The six principal colonies of German Africa, along with native kingdoms and polities, were the legal precedents of the modern states of Burundi, Cameroon, Namibia, Rwanda, Tanzania and Togo.

Title: History of Africa
Content:  All of Sub-Saharan Africa was claimed by European powers, except for Ethiopia (Abyssinia) and Liberia. The European powers set up a variety of different administrations in Africa, reflecting different ambitions and degrees of power. In some areas, such as parts of British West Africa, colonial control was tenuous and intended for simple economic extraction, strategic power, or as part of a long-term development plan. In other areas, Europeans were encouraged to settle, creating settler states in which a European minority dominated. Settlers only came to a few colonies in sufficient numbers to have a strong impact. British settler colonies included British East Africa (now Kenya), Northern

Europeans controlled one tenth of Africa, primarily along the Mediterranean and in the far South. A significant early proponent of colonising inland was King Leopold of Belgium, who oppressed the Congo as his own private domain until 1908. The 1885 Berlin Conference, initiated by Otto von Bismarck to establish international guidelines and avoiding violent disputes among European Powers, formalized the "New Imperialism". This allowed 
Title: German colonization of Africa
Content:  The German colonization of Africa took place during two distinct periods. In the 1680s, the Margraviate of Brandenburg, then leading the broader realm of Brandenburg-Prussia, pursued limited imperial efforts in West Africa. The Brandenburg African Company was chartered in 1682 and established two small settlements on the Gold Coast of what is today Ghana. Five years later, a treaty with the king of Arguin in Mauritania established a protectorate over that island, and Brandenburg occupied an abandoned fort originally constructed there by Portugal. Brandenburg — after 1701, the Kingdom of Prussia — pursued these colonial efforts until 1721, when Arguin was captured by the French and the Gold Coast settlements
