LEAP US History Module 5 The Cold War and Civil Rights: a complete overview of the superpower rivalry, Cold War conflicts, the civil rights movement, Vietnam, and the era of social change

What Module 5 actually demands

Module 5 covers the Cold War Era (roughly 1945 to the 1970s), which is Standard 5 and, combined with the Modern Age, the most heavily weighted slice of the test. It tells two intertwined stories: the global struggle between the United States and the Soviet Union, and the struggle at home to make American freedom real for all citizens. The LEAP work is source based: read a Cold War cartoon, a court ruling, a protest photograph, or a policy excerpt, and use it as evidence.

This guide ties together the matching dot-point pages, each with its own practice questions: the origins of the Cold War, Cold War conflicts and the Red Scare, the civil rights movement, the Vietnam War and the 1960s, and an era of social change.

The origins of the Cold War

The Cold War was the rivalry between American democracy and capitalism and Soviet communism after World War II. As the Soviets imposed communist rule across Eastern Europe (the Iron Curtain), the United States adopted containment: stopping the spread of communism. Containment took form in the Truman Doctrine, the Marshall Plan, NATO, and the Berlin Airlift.

Cold War conflicts and the Red Scare

Containment was tested by force in the Korean War (1950 to 1953), which ended in stalemate. The superpowers raced to build nuclear weapons and to conquer space (Sputnik, NASA, the Moon landing). The Cuban Missile Crisis (1962) brought the world to the brink of nuclear war before a negotiated removal. At home, the second Red Scare and McCarthyism spread fear and reckless accusations of disloyalty.

The civil rights movement

The movement to end segregation won its legal breakthrough in Brown v. Board of Education (1954), overturning Plessy. Using nonviolent protest, the Montgomery Bus Boycott, Martin Luther King Jr., sit-ins, and the March on Washington, activists won public sympathy and forced federal action: the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

The Vietnam War

The United States fought in Vietnam to contain communism under the domino theory, escalating after the Gulf of Tonkin Resolution. The Tet Offensive (1968) widened the credibility gap, and a powerful antiwar movement, fueled by the draft and television, turned opinion against the war. The United States withdrew, the South fell in 1975, and the war left deep distrust and the War Powers Act.

An era of social change

Johnson's Great Society fought a war on poverty and created Medicare and Medicaid. The women's movement, other rights movements, the counterculture, the environmental movement, and the Warren Court broadened the meaning of equality and rights, provoking a backlash that fed the next era.
