It is in a bunch of videos on Youtube. They study it in black history month too...
Just to clarify also, I went to a somewhat experimental (now shut down) Afro-centric junior high social studies program and aced it when I was 12. I studied it less after that, but the video stuff is easy. The continuation of that was more universal, and that was at the same high school where Tupac Shakur went. We basically got the same education up to the point I transferred back to Ohio and he dropped out of school, although he was a few years after me and we never met, I found out we knew a bunch of the same people.

Those were organized by civil rights activists as a counterpoint to various civil organizations which young black men were barred from involvement with.
Another relevant article is the origins of what is loosely called "Folk Nation" originally out of Chicago.
https://en.wikipedia.org/wiki/Folk_Nation and then of course, their rivals "people nation"
https://en.wikipedia.org/wiki/People_Nation Numerous efforts have been made to re-politicize the groups by various leaders and organizations, they have really become their own thing over the years.
I have also been diplomatic enough to hear a lot of the black militant side of the story from people in prison and some of the gang leaders when I was in a gang leader segregation holding area for several months. A lot of people told me a lot of stuff, but I was not able to verify much until after I got out of prison and studied it over and over again on the net.
It was there I first started to hear about some other organizations that were pushing the racial conflict, then at the leadership level, were blackmailing control on people and even turning people in to the FBI. There was a crew of blacks getting around who were going to kidnap, torture and kill the white guys who Al Sharpton said raped Tawana Brawley. They had it all set up to go down and then someone from among them went to check in with Sharpton, tell the Reverend to get ready to make the announcement about justice being done. Then suddenly, they all get busted. Turns out there were three different independent crews who got busted for the same basic thing, and compared notes in prison. At first, they figured someone on Sharpton's staff dimed them off, or a wiretap, then as it kept happening, they compared notes, did their own investigations, they figured out there was no other way - Sharpton did it.
That goes into some political and "club" type organizations of such a sensitive nature that I will no longer discuss them in open forum. What I can say is that groups have largely hijacked a huge portion of the militia movement which is a big part of why this website has shrunk to next to nothing.
