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.

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.

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.

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.

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.

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.
