1K The making of a Superpower: USA, 1865-1975

This breadth option follows the transformation of the United States from a divided nation emerging from civil war into a global superpower, through industrial expansion, economic crisis and recovery, and the rise of federal power. It teaches the period as a study of change and continuity in the economy, the role of government, America's place in the world and, above all, the position of African Americans.

Fig. 1Landmarks of the century: the end of the Civil War (1865), the Wall Street Crash (1929), the end of the Second World War and superpower status (1945), and the Civil Rights Act (1964).

Key points

The United States emerged from the Civil War in 1865 with the Union preserved and slavery abolished, but with the enormous task of reintegrating the defeated South and defining the status of some four million freed people. The period known as Reconstruction attempted to remake the South on new terms, and its central achievements were three constitutional amendments: the Thirteenth abolished slavery, the Fourteenth granted citizenship and the equal protection of the laws, and the Fifteenth affirmed that the right to vote could not be denied on grounds of race. On paper, these amendments promised a revolution in the status of African Americans.
For a time that promise was partly realised. Under federal oversight, African Americans in the South voted, held office and built institutions, and the region's political life was transformed. But Reconstruction faced fierce white resistance, including organised violence and intimidation, and rested on a federal commitment that proved temporary. Northern political will faded, and the disputed election settled by the Compromise of 1877 led to the withdrawal of federal troops from the South, effectively ending Reconstruction and leaving the freed population without federal protection.
The consequences were far-reaching and, for African Americans, tragic. With Reconstruction abandoned, southern states over the following decades erected a system of racial segregation and disenfranchisement — the 'Jim Crow' regime — that stripped away much of what the amendments had promised. The Supreme Court's endorsement of 'separate but equal' facilities in the 1890s gave segregation legal cover. The constitutional guarantees remained on the books, dormant, to be invoked much later; but in practice a rigid racial hierarchy was re-established across the South.
For the breadth student, Reconstruction and its collapse establish the baseline and the central paradox of the whole option. The Fourteenth and Fifteenth Amendments created the legal foundations on which the civil-rights movement would eventually build, so the period plants the seeds of later change. Yet the abandonment of Reconstruction fastened segregation on the South for generations, so it also entrenches a profound continuity of racial injustice. The tension between the promise of the amendments and the reality of Jim Crow runs through the entire century that follows.
Worked example

Assessing the significance of Reconstruction

How would you judge the significance of Reconstruction across the whole period?

  1. 01Short-term significance

    In the short term, Reconstruction's gains were largely reversed: its abandonment after 1877 allowed segregation and disenfranchisement to take hold, so its immediate impact was limited and then undone.

  2. 02Long-term significance

    In the long term, however, the Fourteenth and Fifteenth Amendments provided the constitutional foundation on which the civil-rights movement later built — durable and, decades on, decisive.

  3. 03Judge

    Conclude that Reconstruction was of limited short-term but great long-term significance: it failed to secure rights in its own day but created the legal framework that made their later achievement possible.

Result: Reconstruction is judged of limited immediate but major long-term significance — a failure at the time whose amendments became the foundation of later change.

Exam focus

  • Explain the paradox: the Reconstruction amendments created the legal basis for later civil rights, yet their abandonment entrenched segregation.
  • Use Reconstruction as the baseline for judging long-term change in the position of African Americans.

Typical mistakes

  • Treating the Reconstruction amendments as immediately effective, ignoring how their abandonment left them dormant for decades.
  • Separating Reconstruction from the later civil-rights story rather than seeing it as its foundation.

Fig. 2American superpower rested on several dimensions — economic strength, military might, political and diplomatic leadership, and cultural influence — with the economic base coming first.

Key points

In the decades after the Civil War the United States underwent one of the most rapid industrial transformations in history. The building of a transcontinental railroad network, the exploitation of vast natural resources, and the rise of great industries in steel, oil and manufacturing turned the country into the world's leading industrial economy by the early twentieth century. Enormous business enterprises, associated with figures who became bywords for industrial wealth, dominated key sectors, while mass immigration supplied labour and swelled the cities. This was the age of American economic take-off.
The growth was accompanied by sharp social contrasts that gave the era its critical nickname, the 'Gilded Age' — glittering on the surface, with deep problems beneath. Immense fortunes coexisted with harsh conditions for industrial workers and periodic, sometimes violent, labour conflict. The concentration of economic power in large corporations raised concerns about monopoly and about the influence of business on politics. Meanwhile westward expansion completed the settlement of the continent, with severe consequences for Native American peoples whose lands and ways of life were overrun.
The problems of rapid industrialisation provoked a reforming response in the Progressive Era of the early twentieth century. Reformers sought to curb the power of the great corporations, to clean up politics, to improve conditions for workers and consumers, and to bring a measure of regulation to the economy. Progressivism was not a single movement and its achievements were uneven, but it marked a growing acceptance that government might act to address the social costs of industrial capitalism — an important shift from the earlier faith in unregulated enterprise.
For the breadth student, the Gilded Age and Progressive Era establish two long-run themes. First, the transformation of the American economy into an industrial giant laid the material foundation for the country's later rise to superpower status — economic strength preceded and underpinned global power. Second, the debate over how far government should regulate the economy and cushion its casualties, opened in this period, runs through the New Deal and beyond, making the changing role of the federal government one of the option's central threads.
Worked example

Tracing the changing role of government

How would you argue that the industrial era began a change in the role of government?

  1. 01The starting point

    Establish the Gilded Age baseline: a broadly unregulated economy in which government did little to check big business or protect workers, reflecting a faith in unregulated enterprise.

  2. 02The shift

    Show the Progressive response: growing acceptance that government should regulate corporations and address social costs, marking a real if limited change of principle.

  3. 03Judge the extent

    Conclude that the change was significant in principle but limited in scope — the idea of an active regulatory government took root, but its full expansion awaited the New Deal, so this period began rather than completed the change.

Result: The industrial era is shown to begin the change in the government's economic role — establishing the principle of regulation that the New Deal would later expand.

Exam focus

  • Connect industrial growth to later superpower status: economic strength was the foundation of global power.
  • Explain the Progressive Era as the opening of the long debate over the government's role in the economy.

Typical mistakes

  • Describing industrial growth without noting its social costs (labour conflict, inequality, effects on Native Americans).
  • Treating Progressivism as a single, unified movement with uniform success.

Fig. 3The Crash produced the Depression, which discredited limited government and led to the New Deal and a lasting expansion of the federal role.

Key points

The 1920s were a decade of economic boom, mass consumption and cultural change, but the prosperity rested on unstable foundations, and in October 1929 the Wall Street Crash triggered the descent into the Great Depression. The Depression was the gravest economic crisis in the country's history: banks failed, businesses collapsed, and unemployment reached catastrophic levels, bringing hardship to millions. The scale of the disaster discredited the prevailing belief that government should stand back from the economy and created the conditions for a decisive change in the role of the federal state.
The response was the New Deal of President Franklin Roosevelt, launched from 1933. It was a broad programme of relief for the unemployed and destitute, recovery measures to revive the economy, and reform to prevent a repetition — including new regulation of banking and finance, public works, support for agriculture, and the beginnings of a federal welfare system. The New Deal did not by itself end the Depression (full recovery came with the demands of the Second World War), and it faced criticism from both left and right, but it transformed the relationship between citizens and the federal government.
The most significant long-term consequence of the New Deal was the permanent expansion of federal power. Before the 1930s the federal government played a relatively limited role in the everyday economic life of citizens; the New Deal established the principle that Washington had a responsibility to manage the economy and to provide a measure of social security, and it built the institutions to do so. This was a lasting change of direction that outlived Roosevelt and shaped American government for the rest of the century, whatever later debates about its extent.
For the breadth student, the Depression and New Deal are the decisive turning point in the growth of federal power — the moment when the debate opened in the Progressive Era was resolved, at least for a generation, in favour of a more active government. They also illustrate how a crisis can produce rapid institutional change: the emergency of the Depression achieved in a few years an expansion of the federal role that decades of gradual argument had not. The changed role of government becomes, from this point, a settled feature of the American state.
Worked example

Judging the New Deal's significance

How would you assess whether the New Deal transformed the role of the federal government?

  1. 01The case for transformation

    The New Deal established federal responsibility for managing the economy and providing social security, built lasting institutions, and permanently expanded Washington's role — a genuine change of principle and practice.

  2. 02Qualifications

    Note limits and continuities: it did not end the Depression alone, it left much of the economy in private hands, and it built on foundations laid in the Progressive Era rather than appearing from nothing.

  3. 03Judge

    Conclude that the New Deal did transform the role of government in the sense that mattered most — establishing an active, responsible federal state — while acknowledging it drew on earlier trends and left a mixed economy intact.

Result: The New Deal is judged genuinely transformative of the federal role, establishing an active government, while its limits and Progressive roots qualify the claim.

Exam focus

  • Present the New Deal's central legacy as the permanent expansion of federal power, not merely as a cure for the Depression.
  • Note honestly that the New Deal did not end the Depression by itself — recovery came with the Second World War.

Typical mistakes

  • Claiming the New Deal 'ended the Depression' — it relieved and reformed, but full recovery came with wartime demand.
  • Describing New Deal programmes without analysing their significance for the role of government.

'The New Deal transformed the role of the federal government.' Assess the validity of this view. Plan an answer that weighs change against continuity.

The rise of a superpower#

Fig. 4Industrial strength, magnified by the Second World War, produced the economic and military dominance that underpinned Cold War leadership.

Key points

Across the period the United States moved from relative detachment in world affairs to global leadership. Its entry into the First World War in 1917 signalled a new weight in international politics, though it withdrew afterwards into a more limited engagement. The decisive shift came with the Second World War: the country's vast industrial capacity, mobilised for war after 1941, made it the arsenal of the Allied cause, and it emerged in 1945 as the strongest economy and, with the atomic bomb, the strongest military power in the world. Global leadership, avoided in the 1920s and 1930s, was now embraced.
The foundations of superpower status were, above all, economic and military. Decades of industrial growth had made the United States the world's leading economy, and the war confirmed and extended that dominance while devastating its rivals; the country then used its wealth to shape the post-war order and to rebuild allied economies. Militarily, its armed forces, its atomic monopoly and later its nuclear arsenal gave it unprecedented reach. This combination of economic and military primacy is what the term 'superpower' captures.
The Cold War with the Soviet Union defined America's role in the world for the rest of the period. The United States led the Western alliance, extended its influence across the globe through economic and military commitments, and cast itself as the leader of the 'free world' against communism. This global role brought immense influence but also heavy costs and hard choices, culminating for this period in the long and divisive war in Vietnam, which strained American society, damaged confidence in government and revealed the limits of even superpower strength.
For the breadth student, the rise to superpower status is the option's grand narrative of change, and it should be explained through its foundations rather than merely described. The key argument is that America's global power was built on the economic transformation of the earlier decades: industrial might, confirmed and magnified by the Second World War, was the base on which military and diplomatic superpower stood. The Vietnam War, closing the period, supplies the necessary qualification — that superpower did not mean omnipotence, and that global leadership carried real costs at home and abroad.
Worked example

Was the Second World War the decisive turning point?

How would you argue whether the Second World War was the decisive turning point in America's rise to superpower status?

  1. 01The case for the war

    The war confirmed and magnified US economic dominance, devastated its rivals, gave it the atomic bomb and drew it decisively into global leadership after decades of relative detachment — a strong case for a turning point.

  2. 02The case for longer-term causes

    Set against this the earlier industrial transformation, without which the war effort would not have been possible: the material base of superpower was laid before 1941.

  3. 03Judge

    Conclude that the war was the decisive turning point in America's assumption of the superpower ROLE, but that it built on the long-term economic foundations laid earlier — the war converted latent strength into active global power.

Result: The war is judged the decisive turning point in America's assumption of global leadership, converting the long-built economic base into active superpower — a weighed judgement.

Exam focus

  • Explain superpower status through its economic and military foundations, not as a list of events.
  • Use Vietnam to qualify the narrative: superpower did not mean omnipotence and carried costs at home.

Typical mistakes

  • Describing wars in sequence without analysing how economic strength underpinned global power.
  • Presenting the rise to superpower as smooth and unqualified, ignoring the strains of Vietnam.

Civil rights and the position of African Americans#

The position of African Americans, 1865 and 1975

African Americans: 1865 versus 1975Venn diagram with 2 sets, c. 1865-1900, c. 1975c. 1865-1900c. 1975Emancipationwithout right…Legalsegregation e…Continuingeconomic & so…
Fig. 5Between 1865 and 1975 legal and political status changed decisively (from Jim Crow to civil and voting rights) while economic and social inequality persisted.

Key points

The changing position of African Americans is the thread that most fully tests change and continuity across the whole option. The starting point, after the abandonment of Reconstruction, was a system of legal segregation and disenfranchisement in the South and widespread discrimination elsewhere. For decades the constitutional promises of the Reconstruction amendments lay dormant, and the position of African Americans changed slowly if at all — a long period of profound continuity in racial injustice that any answer on this theme must establish.
Pressures for change built over the first half of the twentieth century: the migration of many African Americans to northern cities, their service and labour in two world wars and the gap that exposed between American ideals and American practice, and the growth of organisations campaigning for rights. The Cold War added a further pressure, since segregation embarrassed a country claiming to lead the 'free world'. These developments prepared the ground, but the decisive breakthrough came in the two decades after the Second World War.
The civil-rights movement combined legal challenge, mass protest and moral argument. A landmark Supreme Court ruling in 1954 declared segregated schooling unconstitutional, reactivating the Fourteenth Amendment; a wave of boycotts, sit-ins, marches and campaigns, met by fierce resistance, kept the issue before the nation; and this pressure produced decisive federal legislation in the mid-1960s — a Civil Rights Act outlawing segregation and discrimination, and a Voting Rights Act securing the franchise. These measures dismantled the legal structure of segregation that had stood since the end of Reconstruction.
Yet the breadth judgement must weigh this real, hard-won legal transformation against persistent continuity. The civil-rights laws ended legal segregation and secured formal political rights — a genuine and major change. But deep economic and social inequality, and the informal barriers of prejudice, persisted well beyond the legal victories, and frustration with the limits of legal change fed more radical currents. The strongest essays argue both sides: a decisive change in legal and political status by the 1960s and 1970s, set against a strong continuity of economic and social inequality — the doubled picture that captures the complexity of the theme.
Worked example

A synoptic judgement on civil rights

Plan a top-band answer to: 'To what extent was the position of African Americans transformed between 1865 and 1975?'

  1. 01Thesis

    Argue a doubled line: the LEGAL and POLITICAL position was transformed — from segregation and disenfranchisement to civil and voting rights — but the ECONOMIC and SOCIAL position changed far less, so transformation is real in one dimension and limited in another.

  2. 02Continuity paragraph

    Establish the long continuity: from the abandonment of Reconstruction to the mid-twentieth century, segregation and discrimination persisted with little change — decades of injustice.

  3. 03Change paragraph

    Trace the decisive legal breakthrough: the 1954 ruling, mass protest, and the mid-1960s civil-rights and voting legislation that dismantled legal segregation and secured the franchise.

  4. 04Qualification and judgement

    Weigh the persistence of economic and social inequality after the legal victories, then conclude that the legal and political position was transformed while economic and social equality remained substantially unrealised — transformation in law, continuity in life.

Result: A synoptic plan that argues decisive legal-political transformation against persistent economic-social inequality, reaching a discriminating verdict across the whole span.

Exam focus

  • Argue change and continuity together: decisive legal/political change by the 1960s against persistent economic and social inequality.
  • Connect the 1950s-60s breakthrough back to the Reconstruction amendments it reactivated, showing the long arc.

Typical mistakes

  • Telling the civil-rights story as unqualified triumph, ignoring the continuity of economic and social inequality.
  • Starting the story in the 1950s and neglecting the long preceding period of Jim Crow continuity.
