Segregation was the enforced separation of racial groups in schools, housing, transportation, and public facilities, designed to maintain white supremacy. In APUSH it anchors the civil rights story from Jim Crow through Brown v. Board (1954) and the Civil Rights Act of 1964 (Units 6-8).
Segregation is the enforced separation of racial or ethnic groups across daily life, including schools, housing, jobs, buses, restaurants, and even the U.S. military. Its purpose was never just "separation." It was a system built to keep a racial hierarchy in place by limiting where Black Americans could live, learn, work, and vote. Historians split it into two types you need to know. De jure segregation was separation written into law, like the Jim Crow statutes of the South. De facto segregation was separation that existed in practice without explicit laws, like housing patterns and school zoning in Northern cities.
For the AP exam, segregation matters most as the thing the civil rights movement was fighting to dismantle. The CED frames Period 8 activism as an effort to "fulfill Reconstruction-era promises" (APUSH 8.6.A), which is your reminder that segregation is a continuity question. It hardened after Reconstruction collapsed, got constitutional cover from Plessy v. Ferguson (1896), and was attacked piece by piece through legal challenges (Brown v. Board, 1954), federal action (desegregation of the armed services, the Civil Rights Act of 1964), and direct action like the sit-ins and nonviolent protest campaigns of the 1950s and 1960s.
Segregation runs through most of Unit 8. Topic 8.6 (APUSH 8.6.A) covers the early legal and political wins against it, including Truman desegregating the armed services and Brown v. Board of Education. Topic 8.10 (APUSH 8.10.A and 8.10.B) covers the 1960s push, where activists used legal challenges, direct action, and nonviolent protest while all three branches of the federal government responded with measures like the Civil Rights Act of 1964. Topic 8.9 connects it to the Great Society, since Johnson's liberalism treated ending racial discrimination as a job for federal power. Topic 8.14 (APUSH 8.14.A) brings in the backlash, as conservatives challenged liberal laws and court decisions in the 1960s and 1970s. Thematically, segregation is prime territory for Politics and Power (PCE) and American and National Identity (NAT), and it is one of the best continuity-and-change threads in the whole course, which is exactly what Topic 8.15 asks you to evaluate.

Jim Crow Laws (Units 6-7)
Jim Crow laws were segregation's legal machinery in the South. They emerged after Reconstruction ended and got Supreme Court approval in Plessy v. Ferguson (1896) with the "separate but equal" doctrine. If an exam question asks where segregation came from, Jim Crow is the answer before you ever get to Unit 8.
Brown v. Board of Education (Unit 8)
Brown (1954) is the legal turning point, ruling that segregated public schools are inherently unequal and overturning Plessy's logic. The CED names it directly as a federal measure promoting racial equality, but remember that resistance slowed actual desegregation for years afterward.
Civil Rights Act of 1964 (Unit 8)
Brown attacked segregation in schools through the courts; the Civil Rights Act of 1964 attacked it in public accommodations and employment through Congress. Together they show all three branches dismantling de jure segregation, which is exactly what APUSH 8.10.B asks you to explain.
The Great Society (Unit 8)
Johnson's Great Society treated segregation and poverty as linked problems that federal power could solve. That belief defined 1960s liberalism, and the conservative backlash against it (Topic 8.14) drives the policy debates that close out Period 8.
Segregation usually shows up as the target of civil rights activism rather than as a standalone definition. Multiple-choice and SAQ stems often pair an image or excerpt about nonviolent protest, like the Greensboro Woolworth sit-ins, and ask you to explain the strategy or its effects, so be ready to connect direct action to the dismantling of segregated public spaces. The 2025 DBQ on the federal government's role from 1932 to 1980 shows how segregation-era policy fits into bigger arguments about federal power. For LEQs, segregation is a gift for continuity-and-change prompts. You can trace it from Plessy (1896) through Brown (1954) to the Civil Rights Act (1964), then complicate your argument by noting that de facto segregation persisted after de jure segregation fell. Always specify which kind you mean, and name the specific measure (Brown, the Civil Rights Act, armed forces desegregation) instead of saying "the government ended segregation."
When the exam says "segregation," check whether it means de jure or de facto. De jure segregation was written into law (Southern Jim Crow statutes) and was struck down by Brown and the Civil Rights Act of 1964. De facto segregation existed without explicit laws, through housing patterns, school district lines, and private discrimination, especially in Northern cities. This distinction explains a pattern the CED highlights, which is that legal victories did not end racial inequality and debates over strategy among activists intensified after 1965.
Segregation was the enforced separation of races in schools, housing, transportation, and public facilities, built to maintain a racial hierarchy after Reconstruction.
De jure segregation was required by law, mainly through Southern Jim Crow statutes upheld by Plessy v. Ferguson (1896); de facto segregation existed in practice without laws, especially in Northern cities.
The CED frames the civil rights movement as an effort to fulfill Reconstruction-era promises, so segregation is best argued as a continuity from the 1870s to the 1960s.
All three branches of the federal government acted against segregation, through armed forces desegregation, Brown v. Board of Education (1954), and the Civil Rights Act of 1964.
Legal victories ended de jure segregation but not de facto segregation, which is why debates among activists over nonviolence grew after 1965 and why progress stayed slow.
Conservative backlash against desegregation laws and court decisions fueled the 1960s-1970s policy debates over federal power covered in Topic 8.14.
Segregation is the enforced separation of racial groups in education, housing, employment, and public facilities, designed to preserve white supremacy. In APUSH it spans Jim Crow laws after Reconstruction through the civil rights victories of the 1950s and 1960s.
No. Brown (1954) declared segregated public schools unconstitutional, but continuing resistance slowed actual desegregation for years, and it did not touch segregation in housing, jobs, or public accommodations. The Civil Rights Act of 1964 and later measures were needed, and de facto segregation persisted even after that.
De jure segregation was required by law, like Southern Jim Crow statutes mandating separate schools and rail cars. De facto segregation existed in practice without explicit laws, through housing patterns and school zoning, and it survived long after de jure segregation was struck down.
Segregation is the broader practice of racial separation; Jim Crow refers specifically to the Southern state and local laws (roughly 1877-1965) that made segregation legally mandatory. Jim Crow is the de jure version of segregation, given constitutional cover by Plessy v. Ferguson in 1896.
All three branches acted, which is the core of APUSH 8.10.B. The executive desegregated the armed services under Truman, the Supreme Court struck down school segregation in Brown v. Board (1954), and Congress passed the Civil Rights Act of 1964 banning segregation in public accommodations.
