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.

Many immigrants do not talk about what they endured back home. They were fleeing that world, and when they left they didn't want to talk about it because there had been pain and heartbreak under the caste system of the South. They didn't want to burden their children with what they had endured.

I mean my mother migrated from Georgia -Rome, Georgia, to Washington, D.C., where she then met my father, who was a Tuskegee Airman who was from Southern Virginia. They migrated to Washington and I wouldn't even exist if it were not for that migration. And I brought her back to Georgia, both my parents, actually.

You must leave this world a better place than it would have been if you had not existed.

There are certain things that we take for granted that simply would not have existed without the great migration. Motown, for example, would not have existed - it simply would not, because Berry Gordy, the founder of it, his parents had migrated from Georgia to Detroit where he founded Motown, and where did he get his talent?

At the beginning of the 20th century, before the migration began, 90 percent of all African-Americans were living in the South. By the end of the Great Migration, nearly half of them were living outside the South in the great cities of the North and West. So when this migration began, you had a really small number of people who were living in the North and they were surviving as porters or domestics or preachers - some had risen to levels of professional jobs - but they were, in some ways, protected because they were so small.

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.
