Just so people are clear on timelines, Reconstruction ended with the election of 1876 and the Compromise of 1877 and election of Hayes. Then the US entered a period generally known as Redemption in the south. It started a little earlier than 1877 and was more powerful in different places, and continued until the early 1910s. The violence in Wilmington is part of that period and redemption is marked by racial violence against Black Americans, the solidifying of Democrat Party rule of the South, Lochner Era jurisprudence gutting the 14th and 15th Amendment, and the development of Jim Crow and segregation.

After WWI, there was a period of racist violence from 1919 to about 1923 that generally coincides with the kicking off with the Red Summer. Chicago's famous riot in 1919 is considered part of the Red Summer. The Rosewood massacre in Florida happened near the end of this period, where there are still incidence of racist violence but they don't happen as frequently and aren't was wide spread.

Tulsa was part of that wave of violence. It's tied to the push by Black Americans for Civil Rights, partially based on their service in WWI and is marked by frequent lynching of veterans returning to the south. There was a pretty consistent pattern of attacking and stealing Black wealth, whether it's things like the looting and burning of Greenwood in Tulsa, or the stealing of land in places like Rosewood.
