The United States since 1945: WACE Modern History
“The United States as a Cold War superpower, domestic change including civil rights, and its role in the world after 1945”
After 1945 the United States emerged as the dominant capitalist superpower, leading the Western bloc through the Cold War and fighting conflicts in Korea and Vietnam. At home, post-war prosperity built a vast consumer society, but the period was also marked by the civil rights movement against racial segregation, the upheavals of the 1960s over Vietnam and social change, and continuing debates over America's role and identity into the early 21st century.
What this dot point is asking
SCSA wants you to explain how the United States developed after 1945 as the leading superpower abroad and as a changing society at home. You need to handle its role in the Cold War and the wider world, its post-war prosperity and the consumer society, the great domestic struggles over civil rights and social change, and the controversies that shook the nation. The elective is examined through source analysis and essays in the external paper.
The United States came out of the Second World War uniquely powerful: its homeland untouched, its economy dominant, and its monopoly on the atomic bomb intact until 1949. It abandoned its pre-war isolationism and took on global leadership of the capitalist world, building the institutions of the post-war order and committing itself to the containment of communism. Its Cold War role, the Truman Doctrine, the Marshall Plan, NATO, the wars in Korea and Vietnam, and the rivalry with the Soviet Union, is examined more fully in the Cold War elective, but it defined American foreign policy for half a century.
At home, the post-war decades brought extraordinary prosperity. The economy boomed, suburbs spread, car ownership and consumer goods became widespread, and a mass consumer culture took shape, broadcast through the new medium of television. The "American Dream" of upward mobility and material comfort seemed within reach for many, though prosperity was unevenly shared and excluded many, especially African Americans and the poor.
The greatest domestic struggle of the period was the African American civil rights movement against legal segregation and disenfranchisement. From the Supreme Court's Brown v. Board of Education decision in 1954, through the Montgomery bus boycott, Martin Luther King's leadership, the 1963 March on Washington, and the Civil Rights Act of 1964 and Voting Rights Act of 1965, the movement transformed American society, though racial inequality persisted.
The 1960s were a decade of upheaval. The civil rights movement won landmark legislation but also faced violent resistance, and frustration in northern cities produced riots and the rise of more radical voices such as Malcolm X and the Black Power movement. The assassinations of President Kennedy in 1963, Malcolm X in 1965, and both Martin Luther King and Robert Kennedy in 1968 scarred the nation. The Vietnam War divided Americans deeply, fuelling a mass antiwar movement and a wider counterculture that challenged established values.
The later decades brought further change and controversy. The Watergate scandal forced President Nixon to resign in 1974, damaging trust in government. New social movements, including second-wave feminism and the environmental and gay rights movements, reshaped society. The conservative resurgence under Ronald Reagan in the 1980s reasserted free-market economics and anti-communism, and the end of the Cold War around 1989 to 1991 left the United States as the world's sole superpower, a position whose responsibilities and limits were debated into the early 21st century.
By 2001 the United States was unmatched in military and economic power, but it remained a society in tension, over race, inequality, immigration and its role in the world. The elective asks you to hold together the story of American power abroad and the story of American change and conflict at home.
A common essay asks you to connect the superpower role to domestic change. Use this structured framework.
Step 1: Establish the superpower role
Show the United States emerging uniquely powerful in 1945, abandoning isolationism, and leading the capitalist world through containment, NATO, and the wars in Korea and Vietnam.
Step 2: Establish post-war prosperity
Trace the consumer society: economic boom, suburbs, car ownership, television and the "American Dream", noting it was unevenly shared.
Step 3: Analyse the great domestic struggle
Show the civil rights movement against segregation, from Brown 1954 to the 1964 and 1965 Acts, transforming society while inequality persisted.
Step 4: Analyse the upheavals
Examine the 1960s: assassinations, the antiwar movement and counterculture, Watergate damaging trust, and new social movements.
Step 5: Connect and judge
Conclude by showing how the Cold War, prosperity and domestic struggle interacted, and judge both the achievements and the deep tensions of American society.
Do not separate American foreign power from American domestic struggle, or treat the United States as simply triumphant. The strongest responses connect the global superpower role to the home front, showing how the Cold War, prosperity, civil rights and the upheavals of the 1960s interacted, and analysing both the achievements and the deep tensions of American society.
Historiographically, debate surrounds the civil rights movement, including the relative importance of national leaders such as King, grassroots local activism, and federal action. Historians also debate the meaning of the 1960s, the legacy of Vietnam and Watergate for trust in government, and whether the post-Cold War "unipolar moment" represented genuine American dominance or an overstretch with its own limits.

WACE 2022-style6 marksWith reference to its origin and purpose, assess the usefulness of Source 1 (a 1950s advertisement for suburban consumer goods) for a historian investigating post-war American society.Show worked answer →
A 6 mark usefulness question wants origin and purpose tied to a judgement relative to the inquiry.
Origin and purpose. State that the source is a commercial advertisement from the 1950s designed to sell consumer goods to suburban families, so it projects an idealised image of prosperity.
Usefulness. Argue it is very useful as evidence of the post-war consumer culture and the "American Dream" image, revealing the values marketed to a prosperous suburban audience. It is less useful as evidence of those excluded from prosperity, especially African Americans and the poor, whom it ignores.
Markers reward the origin-purpose link, a judgement relative to the question, and the recognition that an idealised source reveals aspirations while concealing exclusion.
WACE 2023-style16 marksTo what extent was the United States transformed by the upheavals of the 1960s?Show worked answer →
A 16 mark essay needs a thesis weighing how far the 1960s transformed America, with evidence.
Thesis. Argue that the 1960s transformed American society and politics profoundly through civil rights, social movements and the trauma of Vietnam, though deep continuities in inequality and conservatism remained.
Civil rights. Show the landmark legislation, the violent resistance, and the rise of Black Power radicalising the movement.
Social upheaval. Weigh the assassinations of 1963 to 1968, the antiwar movement and counterculture challenging established values, and emerging movements such as feminism.
Continuity and backlash. Note the conservative resurgence that would follow under Reagan, suggesting limits to the transformation.
Judgement. Conclude that the 1960s were a genuine turning point in rights and culture but provoked a reaction, citing debates over the meaning of the decade.
Markers reward a weighed thesis, accurate evidence, and a clear answer to "to what extent".
