Aligned to AP US History Period 8 (1945-1980).
One step at a time.
The U.S. Cold War strategy of preventing the spread of communism through a combination of military, economic, and diplomatic tools, first articulated by George Kennan and implemented through the Truman Doctrine, Marshall Plan, and NATO.
Example: The Marshall Plan provided $13 billion in economic aid to rebuild Western Europe, based on the theory that prosperous nations would resist communist influence.
A mass movement of the 1950s-60s that used legal challenges, nonviolent direct action, and political organizing to dismantle legal segregation and secure voting rights for African Americans.
Example: The Montgomery Bus Boycott (1955-56) demonstrated that sustained economic pressure through nonviolent collective action could force institutional change.
President Lyndon Johnson's ambitious domestic program (1964-68) that created Medicare, Medicaid, Head Start, and the War on Poverty, representing the largest expansion of the federal safety net since the New Deal.
Example: Medicare provided health insurance for Americans over 65, addressing a crisis in which half of elderly Americans lacked health coverage.
The gradual expansion of U.S. military involvement in Vietnam from advisory roles under Eisenhower and Kennedy to over 500,000 combat troops under Johnson, authorized by the Gulf of Tonkin Resolution rather than a formal declaration of war.
Example: The Gulf of Tonkin Resolution (1964) gave Johnson broad authority to use military force, enabling escalation without Congress formally declaring war.
A period of intense anti-communist suspicion in the early 1950s in which Senator Joseph McCarthy and others used unsubstantiated accusations to blacklist, fire, and intimidate Americans suspected of communist sympathies, suppressing political dissent and civil liberties.
Example: Hollywood blacklists destroyed the careers of screenwriters, directors, and actors accused of communist ties, often based on nothing more than attending a meeting or signing a petition.
A broad set of movements in the 1960s-70s that challenged traditional authority, including the antiwar movement, women's liberation, environmentalism, the Chicano movement, the American Indian Movement, and gay rights activism.
Example: The first Earth Day (1970) drew 20 million participants and led to the creation of the Environmental Protection Agency and landmark environmental legislation.
The political scandal stemming from the Nixon administration's break-in at the DNC and subsequent cover-up, which led to Nixon's resignation and a broader erosion of public trust in government institutions.
Example: The White House tapes, released after the Supreme Court's United States v. Nixon ruling, proved that Nixon had personally directed the cover-up from the Oval Office.
The economic crisis of the 1970s combining stagnant growth, high unemployment, and high inflation, exacerbated by OPEC oil embargoes that quadrupled energy prices and exposed American dependence on foreign oil.
Example: The 1973 OPEC oil embargo caused gasoline shortages, long lines at gas stations, and a recession that challenged the prevailing Keynesian economic framework.
