<em>They created Citizens' Councils, or the White Citizens' Councils (WCC).</em>
Explanation:
The Brown v. Board of Education is a very important part of history and marks racial integration in public schools. This all happened because a young African American girl had to walk over a mile to her black school when there was a white school only a few blocks away.
This case ended up going all of the way to the Supreme Court, which said racial segregation in schools was in fact unconstitutional. This also threatened the idea, "separate but equal." During this time, there was not only racial segregation in public schooling but pretty much everywhere. Movie theaters, water fountains, restaurants, transportation, and even housing are just a few of the things that were segregated during this time.
When racial segregation in public schools was deemed to be unconstitutional, states now had to integrate their schools. This took a long time to complete, as many Southern states did not want this to happen. In order to try to resist the integrating of schools, some Southerners created the White Citizens' Councils. The WCC did awful things, like trying to stop boycotts, firing black Americans, and in some cases harming black Americans as well.
