That's one of the biggest losses, I think, to African American families, is that people, once they left, they turned away from the South. They didn't look back, and they often didn't tell their children about it. They didn't want to talk about it. It was too painful, what they'd gone through and the caste system of the South, which was Jim Crow.

And in some ways, to me, that's one of the inspiring and powerful things about the Great Migration itself. There was no leader, there was no one person who set the date who said, 'On this date, people will leave the South.' They left on their own accord for as many reasons as there are people who left. They made a choice that they were not going to live under the system into which they were born anymore and in some ways, it was the first step that the nation's servant class ever took without asking.

My parents sent me to a school across town, an integrated school, where I had the chance to meet and grow up with people who were from other parts of the world. ... I remember feeling that I would never have anything to contribute on St. Patrick's Day. I couldn't tell the stories that they might have been telling about their forebears and I felt left out.

My parents absolutely did not think of themselves as part of the Great Migration. They knew they were part of a great wave. No one really talked about it in those terms or gave it a name.

Miles Davis, his parents migrated from Arkansas to Illinois, where he had the luxury of being able to practice for hours upon hours. He never would have been able to do that in the cotton country of Arkansas.

People leave when life becomes untenable where they are.
