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 and in Mahatma Gandhi's nonviolent movement in India. 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, including the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Civil Rights Act of 1968.
