I think you will find in the new, curious world that these subjects will begin to be touched upon.
In the past any history taught, about black cultures, seemed to focus only on the slavery aspect and the way it was involved in ''white' history.
However, now society is becoming better educated and hungry for knowledge, then the truth about ancient cultures will become more accessible.
Till now the powers that be have been nervous about this kind of information as they still like the public to believe the same old propaganda, that before it "rescued" the slaves from poverty, that they were somehow lesser people.
Thank God the general public is beginning to see through these old lies.
