They were basically a non-violent mafia group that ran pro wrestling and complained and attempted to squash any competition they had, until they ran into Vince McMahon who was as much a criminal as they were.
Wait... There's some other NWA... A rap group? Never heard of it.
I miss the old days of wrasslin', especially since I grew up in an area that was on the border between two territories. Columbia had Mid-Atlantic Championship Wrestling and Augusta had Georgia Championship Wrestling. I got to see Ric Flair in his early days when he was still learning to style and profile, tho at the time my favorite was Chief Wahoo McDaniel.
