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 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.
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.
