Encyclopedia of Africa. Author(s): The Berlin Conference of 1884â1885 marked the climax of the European competition for territory in Africa, a process commonly known as the Scramble for Africa.
European powers were slow to realise the benefits of claiming land in Africa but when one or two started the rest did not want to miss out. In 1884â5 the Scramble for Africa was at full speed. Thirteen European countries and the United States met in Berlin to agree the rules of African colonisation. From 1884 to 1914 the continent was in conflict as these countries took territory and power from existing African states and peoples.
