The correct answer is Governor Faubus resisted the school’s integration with National Guard troops, and President Eisenhower sent federal troops to enforce integration.
After the Supreme Court case Brown vs. Board of Education (1954) the federal government called for the desegregation of schools all across America. This included Central High School. Central High School was previously an all white school. After Brown vs. Board of Education ruled segregated schools illegal, 9 black students enrolled at Central High School. These individuals would be known as the Little Rock 9.
After enrolling, these students tried to attend Central High School but were kept out by the national guard troops. This was due to Governor Fabius's disagreement with integrating white and black schools. However, President Eisenhower enforced the federal ruling by sending in federal troops to enforce the new ruling, allowing black and white students to attend the same school.
