Did Southern resistance to school integration collapse after 1954?

No, Southern resistance to school integration did not collapse after 1954. While the Supreme Court's Brown v. Board of Education decision declared segregated schools unconstitutional, many Southern states employed various strategies to delay and obstruct integration, including closing public schools and implementing "freedom of choice" plans that maintained segregation in practice. It wasn't until the Civil Rights Movement gained momentum in the 1960s, along with federal intervention, that significant progress was made toward integrating schools in the South.
