Answer: The Bantus civilization :D
Explanation: During a wave of expansion that began 4,000 to 5,000 years ago, Bantu-speaking populations – today some 310 million people – gradually left their original homeland of West-Central Africa and traveled to the eastern and Southern regions of the continent. The Bantus were known for their iron tools and improved agricultural yields and their iron weapons made them formidable military opponents. They were also hunters, animal herders (goats, sheep, and cattle), potters, weavers, and traders, exchanging such goods as salt, copper, and iron ore for those things they needed. This made them superior to the other civilizations at the time.
