The 1931 Attack on greenwood was one of the most significant events in Tulsa's history. Following world war 1, Tulsa was recognized nationally for its affluen African American community known as the Greenwood district this thriving business district and surrounding residential area was referred to as "Black wall Street" in june 1921, a series of events nearly destroyed the entire Greenwood area.
You could do Coyote and Wishpoosh, and look up the myth on Google.
When none of the characters are true, but the setting may be true, and what happens in the story actually happened in real life (at least some- most of it)
hope this helps
