5. 1956 - The strategy of "Massive Resistance" against desegregation

https://encyclopediavirginia.org/entries/massive-resistance/

Virginia closed public schools in 3 areas of the state as a test. Warren County, where I lived for many years, was one of those areas. The white community quickly built schools for their private use. The black students were bussed to schools in surrounding counties.

When the public schools eventually reopened the private white schools remained in operation. The young people attending the public schools were nearly 100% black. Over a period of a few years the white families noticed that the world had not ended with desegregation and the white students returned to the public schools. The private system collapsed soon thereafter and the facilities were sold to the public system.

It was a shameful experiment that caused harm to everyone in the affected communities.
