1F Theme 1 - The changing political environment, 1917-80
This lesson teaches the Pearson Edexcel 9HI0 Paper 1 theme topic The changing
political environment, 1917-80. The topic is about how the United States moved
from post-war Republican "normalcy" to New Deal liberalism, Cold War
superpower politics, Vietnam-era distrust and a conservative reaction by 1980.
Keep one large question in view: did American politics change most because
presidents changed, because ideas changed, or because war changed the domestic
rules of politics?
The Enquiry Frame
This topic is a breadth theme. It is not asking for a biography of every president
from Wilson to Carter. It is asking how the political environment changed:
the assumptions voters held, the powers presidents used, the domestic effect of
war and the arguments that divided liberals and conservatives.
The specification has three strands:
| Strand | What you must be able to explain | Core judgement problem |
|---|---|---|
| A changing presidency | Republican dominance to 1933; Roosevelt's influence; changing leadership styles, 1945-72; decline in confidence, 1968-80 | Did presidents drive change, or mostly respond to crisis? |
| Influences on the political landscape | Rugged individualism to New Deal ideas; Red Scares and anti-communism, 1917-80; liberalism, counter-culture and conservative reaction, c1960-80 | Did the centre of politics move left, right, or back and forth? |
| War and domestic politics | Normalcy and isolationism, 1917-41; emergence as Cold War superpower from 1941; Korea and Vietnam | Did war expand government and presidential power, or create backlash against them? |
A good essay will avoid a simple "America became more liberal" story. There was
real change: the federal government became far more active after 1933, the
presidency became more institutional and media-centred after 1945, and war made
foreign policy a permanent domestic issue. But there were also strong
continuities: suspicion of big government, anti-communism, faith in capitalism,
racial and regional divisions, and the ability of conservatives to turn
liberal reform into a political target.
Use these dates as your anchor points:
| Date | Why it matters |
|---|---|
| 1917-20 | World War I, the Bolshevik Revolution, labour unrest and the First Red Scare shaped the reaction against wartime progressivism. |
| 1920 | Harding's "return to normalcy" captured a desire for limited government, business confidence and fewer foreign commitments. |
| 1929-33 | The Great Depression discredited much of Republican political economy and opened the way for Roosevelt. |
| 1933-38 | The New Deal made federal relief, regulation and social security central to national politics. |
| 1941-47 | World War II and the early Cold War made the United States a superpower and built a permanent national-security state. |
| 1950-53 | Korea militarised containment, damaged Truman and strengthened domestic anti-communism. |
| 1964-65 | Johnson's landslide and Great Society marked the high point of post-New Deal liberal activism. |
| 1968 | Tet, protest, assassinations and Johnson's withdrawal from the election exposed a crisis of liberal authority. |
| 1972-74 | Nixon's landslide was followed by Watergate, impeachment pressure and resignation. |
| 1979-80 | Carter's "crisis of confidence", energy problems, inflation and the rise of the New Right helped make conservatism electorally powerful. |
Normalcy, Republicanism and Limits, 1917-33
The first part of the topic begins with reaction. The United States entered the
First World War in April 1917, mobilised the economy, restricted dissent through
wartime laws and accepted a larger federal role than many Americans were used to.
The war ended in November 1918, but its domestic effects did not disappear. The
Bolshevik Revolution of 1917, strikes in 1919, anarchist bombings and fear of
radical immigrants fed the First Red Scare. Attorney General A. Mitchell
Palmer's raids in 1919-20 showed how anti-radical politics could merge concern
about public order, anti-immigrant feeling and attacks on the left.
This helps explain the rise of Republicanism to 1933. Republicanism here
means the dominance of the Republican Party and its political assumptions, not
the general idea of a republic. In 1920 Warren Harding offered a "return to
normalcy". The phrase worked because many voters wanted release from Wilsonian
wartime mobilisation, moral crusading and internationalism. Harding, Coolidge and
Hoover did not all govern identically, but the 1920s Republican settlement had
recognisable features:
| Feature | Meaning in domestic politics | Limit |
|---|---|---|
| Pro-business government | Lower taxes, high tariffs, support for business confidence and limited regulation were treated as routes to prosperity. | It favoured business and investors more clearly than farmers, workers or the unemployed. |
| Restrained presidency | Harding and Coolidge preferred cabinet government, budget discipline and limited federal activism. | The presidency could look passive when structural problems deepened. |
| Rugged individualism | Hoover argued that the American system rested on self-reliance, voluntary cooperation and opportunity rather than large-scale state direction. | It was less convincing when mass unemployment and bank failures made individual effort insufficient. |
| Anti-radicalism | Communism, socialism, anarchism and militant unionism were cast as threats to Americanism. | It narrowed acceptable politics and could damage civil liberties. |
The "normalcy" mood also explains the commitment to isolationism, 1917-41,
but be careful with the word. The United States did not become economically
isolated. It sought markets, loans, debt repayments and naval agreements. The
Washington Naval Conference of 1921-22, the Dawes Plan of 1924 and the
Kellogg-Briand Pact of 1928 all show continued international engagement.
Isolationism meant avoiding permanent political and military commitments,
especially the type of collective security Wilson had associated with the League
of Nations. The Senate's refusal to ratify the Treaty of Versailles and League
membership in 1919-20 was therefore both a foreign-policy decision and a domestic
political statement: Congress, not the president, would decide how far America
was tied to world conflict.
The weakness of Republicanism was exposed after 1929. The Depression was not
caused by one president, but it destroyed the credibility of the existing
political language. Hoover did not simply "do nothing": he backed the Federal
Farm Board, public works, the Reconstruction Finance Corporation in 1932 and
other limited federal measures. Yet these policies still relied heavily on
voluntarism, loans, local relief and confidence. By 1932, with bank failures,
foreclosures, huge unemployment and the Bonus Army episode damaging Hoover's
authority, many Americans concluded that the old balance between individualism,
business confidence and limited federal action had failed.
That is why 1932-33 is a major turning point in this topic. Franklin Roosevelt's
election did not just replace a Republican with a Democrat. It changed the
argument about what national government was for. Republicanism had risen because
it seemed to promise peace, prosperity and normality after World War I. It
declined because the Depression made normality look like drift.
Roosevelt, New Deal and War Shift, 1933-41
Roosevelt's influence was so important because he changed both policy and
political expectations. In March 1933 he inherited a banking collapse and used
emergency powers, a special session of Congress and radio "fireside chats" to
create a sense of action. The Hundred Days produced a rush of legislation for
banking, relief, agriculture and industry. The Emergency Banking Act and bank
holiday helped restore confidence; later measures such as the Works Progress
Administration, Wagner Act and Social Security Act made federal government a
permanent actor in employment, labour relations and welfare.
This was the shift from rugged individualism to New Deal ideas. The New Deal
did not abolish capitalism and it was often experimental, inconsistent and
pragmatic. Its central political message was different from the 1920s: when
markets failed on a national scale, national government had a responsibility to
intervene.
Rugged individualism
The belief, associated with 1920s Republicans such as Hoover, that Americans should prosper through self-reliance and private enterprise, with limited federal help or regulation.

| 1920s assumption | New Deal assumption | Why the shift mattered |
|---|---|---|
| Prosperity came mainly from business confidence and limited government. | Recovery required federal relief, regulation, public works and financial reform. | The electorate became more willing to judge presidents by economic security. |
| Welfare was mainly local, private or charitable. | The national state had a role in old-age pensions, unemployment support and work relief. | The federal government became part of ordinary citizens' expectations. |
| Presidents should restrain themselves in domestic economic life. | Presidents could claim a mandate to experiment in crisis. | The presidency became more active, communicative and legislative. |
| Anti-radicalism protected American capitalism. | Reform could save capitalism from collapse or revolution. | Roosevelt turned moderate reform into a defence of the system. |
Roosevelt's political genius was to occupy the centre ground of crisis politics.
To conservatives, he could look dangerously collectivist. To socialists and some
populists, he did not go far enough. To many voters, however, he offered action
without revolution. The result was a durable Democratic coalition, helped by
urban voters, many workers, many immigrants, sections of the South and increasing
support from African American voters. Do not turn this into a civil-rights
lesson, but do recognise the political point: the party system was being
reshaped.
There were limits. The Supreme Court struck down some early New Deal measures;
Roosevelt's court-packing plan in 1937 damaged him; the 1937-38 recession
weakened claims of complete recovery; and a conservative coalition of Republicans
and southern Democrats restricted further reform by the late 1930s. The New Deal
therefore created a new political settlement, but it also created a new
conservative target: "big government".
War then altered domestic politics again. In the 1930s, Congress passed
Neutrality Acts because many Americans believed involvement in World War I had
been a costly mistake encouraged by bankers, arms manufacturers and Wilsonian
idealism. Roosevelt was more internationalist than Congress, but he moved
carefully because he needed political support for the New Deal. The 1939
"cash-and-carry" revision and the Lend-Lease Act of March 1941 marked a shift
away from strict neutrality before Pearl Harbor. They showed how the presidency
could use national security arguments to stretch the domestic boundaries of what
was politically possible.
By 1941, then, the political environment had changed twice: first through
Depression and New Deal, then through the approach of world war. A strong exam
answer should see the interaction. Roosevelt's domestic authority helped him
lead opinion towards aid to the Allies; the war then strengthened the
presidency, federal administration and economic planning even beyond the New
Deal.
Cold War Presidency and Anti-Communism, 1941-60
The specification says the United States emerged as a Cold War superpower from
1941. This does not mean the Cold War began in 1941. It means the process that
made the United States a permanent global power began with World War II
mobilisation. The war expanded federal spending, scientific research, military
planning, executive authority and public acceptance that American security could
depend on events far beyond the western hemisphere.
After 1945, this became a Cold War political system. Truman accepted the United
Nations, supported reconstruction, and by 1947 announced the Truman Doctrine.
That doctrine committed the United States to political, military and economic
aid for states threatened by authoritarian or communist pressure. The Marshall
Plan, Berlin Airlift and NATO followed. The National Security Act of 1947
created the National Security Council, the CIA and a more unified defence
structure. These institutions mattered domestically because they gave presidents
new permanent machinery for foreign and defence policy.
The Cold War also reshaped the language of domestic politics. Anti-communism
became a test of patriotism, competence and party loyalty:
| Moment | Domestic political consequence |
|---|---|
| Truman's loyalty programme, 1947 | Federal employees could be investigated for security risks, showing how containment came home. |
| HUAC investigations and Hollywood blacklist | Anti-communism affected culture, labour, government employment and public reputation. |
| "Loss" of China, 1949 | Republicans attacked Democrats for weakness, making Asian communism a domestic electoral issue. |
| Soviet atomic bomb, 1949 | National-security anxiety intensified. |
| McCarthy's allegations, 1950 onward | Anti-communism became a weapon for attacking elites and the State Department. |
| McCarran Internal Security Act, 1950 | Congress overrode Truman's veto, showing that civil-liberties objections could be politically weak in a Red Scare atmosphere. |
