Answer:
Reconstruction
Step-by-step explanation:
The Little Rock Nine case became famous because of a group of African Americans high-school students that challenged racial segregation in a public school of Little Rock Arkansas.
The Supreme Court ruled that school desegregation had to continue in Little Rock, but the state Governor Faubus did not agree with that, he defended that the federal action in desegregation schools was similar to the actions that were taken during the Reconstruction.
Because of that, Faubus shut down all city’s public schools of the year, this decision was outlawed by the Supreme Court in 1959 and the schools were integrated and reopen.
