AP U.S. History / Period 8: 1945–1980
Lesson
Civil rights, the Great Society, and the fracture of consensus
Legal equality advanced while war and backlash split liberalism.
Learning goals
- Explain the Civil Rights Movement as both grassroots and legal strategy.
- Connect Vietnam and later economic trouble to political realignment.
Explanation
Black activists, churches, students, and lawyers challenged segregation and disenfranchisement through boycotts, sit-ins, marches, and court cases. Landmark laws followed years of organizing and violence against the movement. Other groups—women, Latinos, Native nations, gay Americans—used some of the same tools to demand recognition.
Lyndon Johnson's Great Society tried to wage a war on poverty and finish civil-rights legislation. Vietnam, urban unrest, and a later economic slowdown then broke the mid-century liberal coalition. A new conservative argument—that government had grown too large and that social change had gone too far—gained strength by 1980.
Key terms
- Civil Rights Movement. The long campaign to end legal segregation and secure equal citizenship, especially for Black Americans.
- Great Society. 1960s federal programs aimed at poverty, education, health coverage, and civil rights.
Common mistakes
- Reducing civil rights to one speech or one court case.
- Treating 1968–1980 as random chaos instead of a reaction to war, rights, and the economy.

Take your time—this is practice, not a test.
Answer explanation
Why did some Americans support civil-rights laws and later reject Great Society liberalism?
Answer. They might accept legal equality yet oppose new spending, urban unrest, or the Vietnam War that shared the same political coalition.
Period 8 is a story of a coalition forming and then splitting, not of one mood.
