10 Conflict and Social Change

A period of conflict and change

During the 1960s and 1970s, war, protest, political crisis, and social change transformed the United States. The Vietnam War divided the country, while civil rights activism helped inspire movements seeking equality and greater self-determination. Economic hardship and political scandal also challenged Americans’ confidence in government.

The Vietnam War and its consequences

The United States became increasingly involved in Vietnam during the Cold War, supporting South Vietnam against communist North Vietnam and its allies. After Congress passed the Gulf of Tonkin Resolution in 1964, President Lyndon B. Johnson greatly expanded U.S. military involvement. By 1965, American combat troops were fighting in Vietnam, and a military draft brought the war directly into many families’ lives.

In January 1968, North Vietnamese and Viet Cong forces launched the Tet Offensive, attacking cities and other targets across South Vietnam. U.S. and South Vietnamese forces eventually retook the captured areas, and the attackers suffered severe losses. However, the offensive’s scale contradicted official assurances that victory was near. Television coverage and news reporting deepened public doubts, opposition to the war grew, and in March 1968 Johnson announced that he would not seek reelection.

President Richard Nixon pursued Vietnamization, the gradual transfer of combat responsibility to South Vietnamese forces, while expanding the war into Cambodia and Laos. The Paris Peace Accords, signed on January 27, 1973, provided for U.S. troop withdrawal and the return of American prisoners of war, but did not end fighting between Vietnamese forces. North Vietnamese forces captured Saigon on April 30, 1975, ending the war and reunifying Vietnam under communist rule. The conflict left deep divisions in American society and increased skepticism about official claims and military intervention.

Movements for equality and environmental action

The civil rights movement continued to challenge racial discrimination through student sit-ins, marches, boycotts, and organizing campaigns. The Selma marches highlighted barriers to Black voting. Congress then passed the Voting Rights Act of 1965, which prohibited discriminatory voting practices and authorized stronger federal enforcement. Activists also pressed for economic opportunity and an end to segregation in housing and public life.

Other movements used tactics such as protest and community organizing, and called for federal action. The women’s movement campaigned against discrimination and for equal opportunity; Title IX, enacted in 1972, prohibited sex discrimination in federally funded education programs. The Chicano movement called attention to Mexican American civil rights and educational inequality. Native American activists asserted tribal sovereignty and self-determination, and the 1969–1971 occupation of Alcatraz brought national attention to these demands. After the 1969 Stonewall uprising against a police raid in New York City, gay and lesbian activism became more visible and organized. These movements had distinct goals, but together broadened public debate about who held power and whose rights government should protect.

Environmental concerns also became a major public issue. On the first Earth Day, April 22, 1970, millions of people took part in demonstrations and educational events. Growing public attention contributed to the creation of the Environmental Protection Agency that year and strengthened the push for environmental regulation.

Protest, violence, and political crisis

The year 1968 captured the era’s turbulence. Martin Luther King Jr. and Senator Robert F. Kennedy were assassinated, antiwar protests intensified, and police clashed with demonstrators outside the Democratic National Convention in Chicago. In 1970, protests widened after the U.S. expansion into Cambodia. At Kent State University in Ohio, National Guard troops shot and killed four students during an antiwar demonstration. The event became a symbol of conflict between protest movements and public authorities.

Political trust faced another crisis in the 1970s. The Watergate scandal began with a 1972 break-in at Democratic Party offices and expanded into an investigation of attempts to conceal the administration’s connection to it. In 1974, the Supreme Court ordered President Nixon to turn over White House recordings, and the House Judiciary Committee approved articles of impeachment. Nixon resigned that year. Watergate demonstrated the importance of investigative reporting, congressional oversight, and limits on presidential power.

Economic uncertainty and changing public life

Daily life changed amid economic uncertainty. The 1973 oil crisis contributed to rising prices and recession, while unemployment increased. Women’s participation in the workforce grew, and education and employment opportunities became prominent subjects of public debate.

Television news, expanding youth culture, and mass demonstrations made national conflicts more visible in people’s homes and communities. Together, these developments exposed deep divisions and weakened trust in government while expanding public debate about equality, citizenship, and the proper limits of political power.
