Little Rock Nine & Sit-Ins.
Nearly 3 years after the Brown v. Board case occurred with its ruling that schools must be desegregated is when Little Rock high school would have its first African American students. However the Arkansas Governor, Orval Faubus, would end up mobilizing the national guard to prevent the 9 African American students from entering the school under the pretense to preserve order. However President Eisenhower would eventually send in the 101st air division as well as remove the National guard from the governors control so that the students could attend the high school.
However this was only for the desegregation of schools but it was surely a good start. Another way to push integration peacefully was through sit-ins where a group of people would ask to be served but would be denied or just ignored and they would just wait there until they were either thrown out or arrested.
These peaceful acts spurred the nation into change and people were siding with integration because a lot of people were seeing the atrocities done first hand because of television which broadcast some of these events nationwide. Both of these events help push the nation into being more integrated and for congress to pass laws to prevent segregation.
