nope, I'm talking about Zimbawe
About Zimbabwe, I guess you never heard about "Great Zimbabwe" and the impressive buildings from the Shona civilization? A huge city built around the 10th century and competing with European cities of the same period. Many kingdoms in these regions were sophisticated trade states trading gold and ivory. But well when you are an ignorant such as Karl I guess you just do not know what you are talking about.
About "negroids", you have yet to prove why they would be inferior.
If you want more examples of old advanced sub saharan civilizations, I can give you some more: beside the Millenias old Ethiopian civilization, that in Antiquity was a superpower and an empire dominating both the African North Eastern region and the Southern Arabic one (the Ethiopians colonized parts of Arabia); you had also the Nubian civilization that was competing with the Egyptian civilization 3000-4000 years ago or more. In the greatest period of the Nubians, Europeans were still living in huts and hunting aurochs and rising stones for their primitive deities, whereas the Nubians had an advanced civilization close to the Egyptian one, building pyramids and huge cities such as Meroe, a huge army, and with Nubian monarchs wearing refined clothes, jewels and gold. During some centuries the Nubian Pharaoh (known as "Black Pharaohs") even dominated the Mighty Egypt. Nubia was also the only state to resist against the Islamic conquests for centuries (from the 7th century to the 12th century), the Arab raiders feared the seasoned Nubian archers that were unmatched and known for their strength and had to make a treaty known as Baqt (this treaty was unprecedented in the history of the Arab conquests. It is also unmatched in that it largely blocked the spread of Islam and the Arabs for half a millennium).
