I see all this blind romanticization and misguided pride about how Africa would've been at the top if it hadn't been for those meddling foreigners. That's completely inaccurate and deluded. Africa had all the time in the world to develop, just like Europe and Asia had. But, what did Africa do on the world stage in all that time? Not much. It stayed stagnant for centuries on end. It's not like the Europeans had a greater advantage to innovate, either. God didn't give them a guidebook or extra time.
If others hadn't come to Africa and brought technology and scientific knowledge, much of sub-saharan would still be living in tribal kings and hunting to survive. Heck, it's even 2020 and most of Africa doesn't even have electricity. But, I bet you're going to blame that on the Europeans, like those Africans would've had it without them. While the East and West were developing fields in mathematics, science and literature, Africans were frolicking in grass fields- completely satisfied with the status quo. (hyperbole btw)
What are the areas of africa who had the most developed civilizations? north africa, west africa(mali) and horn of africa(ethiopia mainly but also somali Sultanates ) + Sudan(nubian).
The nubians and axum in 300CE were much much more developed than northern europeans. Nubians and ethios had a written language much before some white people like Slavs who got it from the greeks in the middle ages(cyrillic). Ethiopians had a written tradition in the IV century, Slavs got it from the greeks only 5 centuries later. Before the renaissance life in Ethiopia, Nubia, Mali etc were not much different than in Europe and keep in mind that these countries are still disadvantaged by geography. (Desert, isolation etc)
What do all these african areas have in common? They are key areas for trade and Cultural exchange. Why was southern eurooe 100times more developed than the North in ancient times? Again key area for trade and Cultural exchange. It's not a coincidence that civilization started in mesopotamia/nile valley and not in siberia or the congo rainforest
Most of africa has been completely isolated by deserts or forests and this explains the lack of development. If germanic tribes never came in contact with romans they would be exactly like some african tribes today. This explains why africa was left behind, geography and basically few contacts with the outside eorld
Let's talk about meddling by foreigners. Slavery and colonialism destroyed Africa or at least prevented any further development in isolated areas. Especially in west africa slavery had a huge impact, colonial exploitation destroyed institutions. If africa was never colonized and instead got in trade relations with Europe it would be similar to south east asia.
