The Kingdom of Kush--- Though often overshadowed by its Egyptian neighbors to the north, the Kingdom of Kush stood as a regional power in Africa for over a thousand years. This ancient Nubian empire reached its peak in the second millennium B.C. when it ruled over a vast swath of territory along the Nile River in what is now Sudan
The Land of Punt--- Few African civilizations are as mysterious as Punt. Historical accounts of the kingdom date to around 2500 B.C., when it appears in Egyptian records as a “Land of the Gods” rich in ebony, gold, myrrh, and exotic animals such as apes and leopards. Egyptians are known to have sent huge caravans and flotillas on trade missions to Punt
Africa had several advanced civilizations during the Middle Ages. The kingdom of Zimbabwe, founded by the Shona people, was the largest kingdom in southern Africa. The people of this kingdom built a grand stone palace with gigantic walls. Timbuktu, a city in the kingdom of Mali, was a center of Islamic scholarship. The people of these kingdoms traveled across the Sahara to conduct trade. They traded with countries as far away as India and China.
