Which of the following occurred in Little Rock Arkansas after the Supreme Court declared segregation in public schools unconstitutional in Brown v. Board of Education of Topeka?

After the Supreme Court's decision in Brown v. Board of Education in 1954, Little Rock, Arkansas, faced significant resistance to desegregation. In 1957, the Little Rock Nine, a group of nine African American students, attempted to integrate Central High School but were initially prevented from entering by Governor Orval Faubus, who called in the National Guard. This led to a national crisis, prompting President Eisenhower to intervene by sending federal troops to ensure the students could attend school. This event highlighted the intense struggle over civil rights and desegregation in the South.
