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.

Anything that could be conceived of that would separate black people from white people was devised and codified by someone in some state in the South. There were colored and white waiting rooms everywhere, from doctor's offices to the bus stations, as people may already know.

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.

The suburbanization and the ghettos that were created as a result of the limits of where [African-Americans] could live in the North [still exist today.] And ... the South was forced to change, in part because they were losing such a large part of their workforce through the Great Migration.

What I love about the stories of the Great Migration is that this is not ancient history; this is living history. Most people of color can find someone in their own family who had experienced a migration of some kind, knowing the sense of dislocation, longing and fortitude.

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.

Sometimes in some places they would actually stop the train - keep the train from stopping at a particular station because they saw that there were so many black people there waiting to board and so therefore those people wouldn't get to leave.
