Before Colonialism & What Could have Been

Max Fisher in the Washington Post:
This map of indigenous African empires is not exhaustive. It spans two thousands years from 500 B.C. to 1500 A.D., so these empires were not concurrent; some existed centuries apart. But it shows that, like with North America and perhaps even more so, sub-Saharan Africa was rich with vast and powerful empires long before the Europeans arrived. (One of the biggest, Ethiopia, was actually unusually and perhaps uniquely successful in resisting European imperialism.) The Songhai Empire, at its peak in the 14th century, was a global center of culture and learning, based in the still-famous mosques of Timbuktu.
Nikolaj Cyon

Historical counterfactuals aren't much more than informed speculation, but this one is still awfully interesting. Made by the Swedish artist Nikolaj Cyon, the map asks what Africa would look like today if colonialism had never happened. (Africa's present-day borders were determined largely by colonialism, which continues to create lots of very big problems.) Cyon drew these boundaries based on a study of political and tribal units in 1844, the eve of Europe's "scramble for Africa." He oriented it with south at the top to subvert the traditional Europe-on-top orientation. You can see it here with north on the top, if that's easier for you to read.
