At 9 p.m. Wednesday, KOCO 5 will air a special presentation called "Chronicle: Grit of Greenwood." You'll hear from Tulsa Race Massacre descendants, experts and exclusive interviews from survivors not seen in decades.Black Wall Street was a thriving community in Tulsa's Greenwood District. Business owners, lawyers and more helped build the area into one of the most prominent neighborhoods in Tulsa.Then, during an 18-hour period on May 31, 1921, spanning into June 1, 1921, the thriving community was disintegrated by hate. The atrocity is a dark story that many in the U.S., even much of Oklahoma, did not know about until recently. "It started in the Drexel Building with a shoeshiner named Dick Rowland," Dexter Nelson II said. "There was an altercation with him and a white elevator operator named Sarah Page."What unfolded turned into one of the worst acts of racial violence in American history for decades and was eliminated from school history books and museums in Oklahoma.“Hundreds of Black people are murdered. Every house burned to the ground. Nothing, there was no precedent for this anywhere,” said Bruce Fisher, who has been the curator for the Oklahoma History Center since 1999 and is largely responsible for their African American exhibit created six years after he arrived.Newspaper headlines, such as the one from the "Black Dispatch," chronicled only a fraction of the untold story. There were days of mass chaos and destruction in the Tulsa Greenwood District, hundreds of people were killed, Black Wall Street was burned to ashes and African Americans' dreams of hope and prosperity were destroyed.Fisher believes fear was a driving factor for why this critical part of history remained dormant for more than 70 years.“You had people who didn't know whether it would happen again," Fisher said. “You had people in smaller communities, 'If it happened there, it might happen to us.' I think that's one of the reasons people didn't really talk about it."Fisher said many even denied the massacre ever took place despite the lives lost and damage done.Fisher said some survivors, including his own grandparents, moved to all-Black towns in Oklahoma or out of state altogether. The stories were passed down to their descendants.Fisher said it wasn't until 75 years after the massacre in 1996 when State Rep. Don Ross and Sen. Maxine Horner created the Oklahoma commission, which provided a safe place for survivors to speak out and be recorded.“You know this was trauma on steroids," Fisher said.With the 100th anniversary of the Tulsa Race Massacre approaching, Fisher said it's up to the remaining survivors to continue telling their stories, for historians to accurately document them and for schools to teach it.
