Chancellor Otto von Bismarck hosted representatives of fourteen nations to formalize rules for European claims on Africa, including the requirement of 'effective occupation.' The conference, which ran until February 1885, accelerated the Scramble for Africa, imposing borders that ignored ethnic and political realities and shaped the continent's colonial and postcolonial map.
Fourteen nations sent delegates to Bismarck's residence on Wilhelmstrasse, but not a single African ruler, chief, or diplomat was invited to a conference that would determine the fate of their continent. The stated purpose was almost administrative: to agree on free trade along the Congo and Niger rivers and to establish rules preventing European powers from clashing over African territory.
In practice, the conference legitimized the drawing of borders with rulers and compasses, slicing through kingdoms, ethnic groups, and trade networks that had existed for centuries. King Leopold II of Belgium walked away with personal control over the Congo Free State, a territory eighty times the size of Belgium, which he would run as a private slave-labor extraction operation responsible for millions of deaths.
The principle of 'effective occupation' set off a frantic rush: within a few years, European flags flew over nearly ninety percent of African territory, up from about ten percent before the conference. The straight-line borders drawn in Berlin's drawing rooms still define most African nations today, a lingering colonial fingerprint on the map.
