1945–1968: Cold War, Civil Rights, and Cultural Change
The United States and Soviet Union locked into a global Cold War. At home, the civil rights movement challenged racial segregation and won landmark legislative victories. The postwar boom created a mass middle class. The 1960s brought the moon landing, cultural upheaval, and political assassinations.
Why This Era Matters
The civil rights movement of this era transformed American law and society, extending the promises of the Declaration of Independence and Constitution to Black Americans. The Cold War shaped foreign policy, domestic politics, and American identity for four decades.

Major Events in This Era
Brown v. Board of Education
The Supreme Court unanimously ruled that racial segregation in public schools was unconstitutional — overturning Plessy v. Ferguson and sparking the modern civil rights movement.
Civil Rights Act of 1964
President Johnson signed the Civil Rights Act of 1964, outlawing discrimination based on race, color, religion, sex, or national origin — the most comprehensive civil rights legislation since Reconstruction.
Voting Rights Act of 1965
The Voting Rights Act outlawed discriminatory voting practices that had disenfranchised Black voters in the South for nearly a century — giving real force to the 15th Amendment at last.
Apollo 11 Moon Landing
Apollo 11 landed on the Moon and Neil Armstrong became the first human to walk on its surface — the greatest technological achievement in American history and a defining moment of the 20th century.
