Some of my cousins grew up in Springfield (not Chicago, btw). We spent a lot of time there when I was growing up. They had a swim pool, so we'd actually spend the hottest part of the summer there several years, and just live in the pool. But in all that time in Springfield, I never heard a word about the riot. I only learned about them when a friend began to serve a church in Virden, about 20 miles south of Springfield. She learned about the Virden Mine War, (

Some historians see the two events as closely related, because many of the African American miners who were forced out of Virden (after being brought there as strikebreakers, because they desperately needed the work) settled in the "Badlands" neighborhood of Springfield, where the worst of the rioting happened.
Until my colleague there began talking about the riots, I knew not a thing. It is especially sad that it happened in Lincoln's hometown.
It's also where Barack Obama made his announcement of candidacy. A black man announcing for the presidency in the city where these awful riots took place.
We're making some progress. Slowly but surely.
