The Berlin Conference Drew Africa's Borders in 15 Weeks

On November 15, 1884, representatives from fourteen European nations and the United States sat down in Otto von Bismarck's chancellery in Berlin to negotiate the rules for claiming African territory. No African was present. The continent was represented only by maps, most of which had vast interior regions simply labeled 'unknown.'

The conference lasted fifteen weeks. Its immediate trigger was the Congo: King Leopold II of Belgium wanted personal ownership of a territory eighty times the size of his country, and Bismarck called the meeting partly to prevent any single power from dominating the scramble before rules could be set. The resulting General Act established that any European power claiming African territory had to notify the others and demonstrate 'effective occupation' — meaning an actual administrative presence, not just a flag planted on a beach.

The borders that emerged followed rivers, straight lines of latitude and longitude, and the range of artillery rather than the actual boundaries of the roughly 10,000 political units — kingdoms, chiefdoms, nomadic territories — that existed across the continent. The Somali people were divided among British, French, Italian, and Ethiopian jurisdictions. The Malinke were split between French and British colonies. The Ewe between German Togoland and British Gold Coast.

In 1880, Europeans controlled roughly 10 percent of Africa. By 1914, they controlled 90 percent. The conference didn't cause the scramble — that had been underway for decades — but it set the framework for how the division would be formalized, adjudicated, and eventually inherited by the independent states that emerged after decolonization in the 1950s and 60s. Most of those inherited borders have held, which is itself a testament to how thoroughly the European framework displaced the ones that existed before.
