School segregation in the United States in the context of "Ruby Bridges"

The white flight, also known as white exodus, refers to the sudden or gradual large-scale migration of white people from areas becoming more racially or ethnoculturally diverse to more racially homogenous suburban or exurban regions. The term has more recently been applied to other migrations by whites from older, inner suburbs to rural areas, as well as from the American Northeast and Midwest to the milder climate in the South and West. The term 'white flight' has also been used for large-scale post-colonial emigration of whites from Africa, or parts of that continent, driven by levels of violent crime and anti-colonial or anti-white state policies. Starting in the 1950s and 1960s, the terms became popular, especially in the United States.

Migration of middle-class white populations was observed during the civil rights movement in the 1950s and 1960s out of cities such as Baltimore, Cleveland, Detroit, Kansas City and Oakland, although racial segregation of public schools had ended there long before the Supreme Court of the United States' decision Brown v. Board of Education in 1954. In the 1970s, attempts to achieve effective desegregation (or "integration") by means of busing in some areas led to more families' moving out of former areas. More generally, some historians suggest that white flight occurred in response to population pressures, both from the large migration of blacks from the rural Southern United States to urban cities of the Northeastern United States, Midwestern United States and the Western United States in the Great Migration and the waves of new immigrants from around the world.

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, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

Following the American Civil War (1861–1865), the three Reconstruction Amendments to the U.S. Constitution abolished slavery and granted citizenship to all African Americans, the majority of whom had recently been enslaved in the southern states. During Reconstruction, African-American men in the South voted and held political office, but after 1877 they were increasingly deprived of civil rights under racist Jim Crow laws (which for example banned interracial marriage, introduced literacy tests for voters, and segregated schools) and were subjected to violence from white supremacists during the nadir of American race relations. African Americans who moved to the North in order to improve their prospects in the Great Migration also faced barriers in employment and housing. Legal racial discrimination was upheld by the Supreme Court in its 1896 decision in Plessy v. Ferguson, which established the doctrine of "separate but equal". The movement for civil rights, led by figures such as W. E. B. Du Bois and Booker T. Washington, achieved few gains until after World War II. In 1948, President Harry S. Truman issued an executive order abolishing discrimination in the armed forces.

In the United States, school integration (also known as desegregation) is the process of ending race-based segregation within American public, and private schools. Racial segregation in schools existed throughout most of American history and remains an issue in contemporary education. During the civil rights movement school integration became a priority, but since then de facto segregation has again become prevalent.

School segregation declined rapidly during the late 1960s and early 1970s. Segregation appears to have increased since 1990. The disparity in the average poverty rate in the schools whites attend and blacks attend is the single most important factor in the educational achievement gap between white and black students.

Historically Black colleges and universities (HBCUs) are institutions of higher education in the United States that were established before the Civil Rights Act of 1964 with the intention of serving African American students. Most are in the Southern United States and were founded during the Reconstruction era (1865–1877) following the American Civil War. Their original purpose was to provide education for African Americans in an era when most colleges and universities in the United States did not allow Black students to enroll.

During the Reconstruction era, most historically Black colleges were founded by Protestant religious organizations. This changed in 1890 with the U.S. Congress' passage of the Second Morrill Act, which required segregated Southern states to provide African Americans with public higher education schools in order to receive the Act's benefits. Separately, during the latter 20th century, either after expanding their inclusion of Black people and African Americans into their institutions or gaining the status of minority-serving institution, some institutions came to be called predominantly Black institutions (PBIs).
