American Civil Rights Movement: Little Rock Crisis: The governor of Arkansas calls out the National Guard to prevent African American students from enrolling in Little Rock Central High School, resulting in the lawsuit Cooper v. Aaron the following year.

The civil rights movement was a social movement in the United States from 1954 to 1968 which aimed to abolish legalized racial segregation, discrimination, and disenfranchisement in the country, which most commonly affected African Americans. The movement had origins in the Reconstruction era in the late 19th century, and modern roots in the 1940s. After years of nonviolent protests and civil disobedience campaigns, the civil rights movement achieved many of its legislative goals in the 1960s, during which it secured new protections in federal law for the civil rights of all Americans.

The Little Rock Nine were a group of nine African American students enrolled in Little Rock Central High School in 1957. Their enrollment was followed by the Little Rock Crisis, in which the students were initially prevented from entering the racially segregated school by Orval Faubus, the Governor of Arkansas. They then attended after the intervention of President Dwight D. Eisenhower.

Little Rock Central High School (LRCH) is an accredited comprehensive public high school in Little Rock, Arkansas, United States. The school was the site of the Little Rock Crisis in 1957 after the U.S. Supreme Court ruled that segregation by race in public schools was unconstitutional three years earlier. This was during the period of heightened activism in the civil rights movement.

Cooper v. Aaron, 358 U.S. 1 (1958), was a landmark decision of the Supreme Court of the United States that denied the school board of Little Rock, Arkansas the right to delay racial desegregation for 30 months. On September 12, 1958, the Warren Court delivered a decision that held that the states are bound by the Court's decisions and must enforce them even if the states disagree with them, asserting the judicial supremacy established in Marbury v. Madison (1803). The decision in this case upheld the rulings in Brown v. Board of Education and Brown II that had held that the doctrine of separate but equal was unconstitutional.
