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.

Well, I'm a daughter of the great migration as, really, the majority of African Americans that you meet in the north and west are products of the great migration. It's that massive. Many of us owe our very existence to the fact that people migrated.

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.

It occurred to me that no matter where I lived, geography could not save me.

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.

America is made up of people who came from someplace else. Even the Native Americans came over the Bering strait... America is what it is because people came from someplace else.

It was illegal for black people and white people to play checkers together in Birmingham. And there were even black and white Bibles to swear to tell the truth on in many parts of the South.
