One hundred years ago this week, from May 31 and June 1, 1921, a mob targeted and destroyed nearly 40 blocks of a wealthy black neighborhood in North Tulsa, Oklahoma. No one knows how many people died, no one was ever convicted, and no one really talked about it nearly a century later. This is the story of the Tulsa Race Massacre and why it's important that you know it.

At least 1,256 homes, along with churches, schools, businesses and even a hospital were deliberately burned or destroyed. Recently found documents are helping historians and researchers better understand the events that took place. And lots of this work is happening by staff at the National Museum of African American History and Culture. In fact, part of the Power of Place exhibition at the museum is dedicated to the events of the massacre.
