There was an event that triggered it, the massacre, and that is that a young black guy got into an elevator in downtown Tulsa. And then the leaders in the black community said, well, you know, this is wrong. So they marched down to the courthouse and tried to release him from jail and there was a backlash against them. That was kind of what you call the match, I don't know, the struck. But leading up to that time, a couple of things were going on. One is that the prosperity in that Greenwood community was overshadowing a lot of the things going on in white neighborhoods in Tulsa.
