European powers carved up an entire continent at a conference where no African was invited

At the Berlin Conference of 1884-85, representatives of European powers met to regulate their colonization of Africa and avoid fighting each other over it. They drew borders across the map with little regard for existing ethnic, linguistic, or political boundaries. Within a few decades the conference's participants controlled roughly 90% of African territory, up from about 10% before it.
