Why do you know little about ancient kush?

Answer 1

For three main reasons: 1. It was a VERY long time ago 2. Kush was on the edge of the ancient world, they defended very well against invaders so even in ancient times many fantastic legends were told about the Kushites and 3. There has been severe prejudice against Black people for the past 500 years (i.e. enslavement followed by colonisation of the entire continent, etc) which means a lot of the history was sidelined until recently
