What this dot point is asking

NESA expects you to set the scene for the National Study by sketching the United States as it emerged from World War I. Strong answers integrate the political deadlock over the Treaty of Versailles, the post-war economic turmoil, the racial and ideological tensions of 1919, and the long shadow of the war on American society. The point is not to tell every story but to identify the structural features that explain the 1920s.

In plain English

Imagine a team that just won a hard-fought championship, then walks into the changing room and starts fighting each other. That was America in 1919. It had helped win World War I and was now the richest, most powerful country on earth - half the world's gold sat in its banks - yet at home almost everything was going wrong at once.

Prices had nearly doubled, so even people with jobs felt poorer, and around 4 million workers walked off the job in strikes. Many Americans, terrified by the recent communist revolution in Russia, decided the strikers must be secret Bolsheviks; the government rounded up about 10,000 suspected radicals and deported hundreds. In the same hot summer, white mobs attacked Black neighbourhoods in city after city - the "Red Summer" - while a flu pandemic killed more Americans than the war had. And the President, Woodrow Wilson, was fighting his own Senate over whether to join a new League of Nations - a fight he lost after a stroke left him an invalid. So 1919 is less a year of victory parades than a country, exhausted and frightened, turning its anger inward and pulling up the drawbridge to the world.

The answer

The political system

The United States was a federal republic with a written constitution, a President with a four-year term, a Senate of two members per state, a House of Representatives elected biennially, and a Supreme Court of nine justices. The Seventeenth Amendment (1913) had introduced the direct election of senators. The Nineteenth Amendment (women's suffrage) was passed by Congress in June 1919 and ratified on 18 August 1920.

Woodrow Wilson (Democrat) was the twenty-eighth President, in his second term. Republicans held both houses of Congress after the November 1918 mid-term elections, a setback Wilson had not seen coming. Politics in 1919 was dominated by the Treaty of Versailles, by the labour disputes of the year, and by the Red Scare.

The economy

The American economy was the world's largest, having overtaken Britain before 1900. Industrial production was around 35 per cent of the world total. The war had turned the United States from a debtor to a creditor nation; Britain and France owed Washington around 10 billion dollars.

The transition to peace was rough. War contracts were cancelled; 4 million troops returned to the labour force. Inflation hit around 15 per cent in 1919. The cost of living roughly doubled between 1914 and 1920. Around 4 million workers participated in over 3,600 strikes in 1919, including:

The Seattle General Strike (6 to 11 February 1919), the first general strike in American history.
The Boston Police Strike (9 September 1919) suppressed by Governor Calvin Coolidge.
The Great Steel Strike (22 September 1919 to 8 January 1920), defeated by US Steel.

The strikes were widely portrayed as Bolshevik subversion. They prepared the ground for the conservative reaction of the 1920s and for the long quiet of organised labour through to the Wagner Act of 1935.

Society

American society in 1919 was deeply unequal and deeply divided.

Racial conflict was at the centre. The Great Migration of African Americans to northern cities (around 500,000 between 1916 and 1919) collided with returning white veterans. The Red Summer of 1919 saw at least 25 race riots, including:

Chicago, 27 July to 3 August 1919, after a Black teenager Eugene Williams was killed at a segregated beach. 38 dead (23 Black, 15 white), over 500 injured, around 1,000 Black families left homeless.
Washington DC, 19 to 24 July 1919.
Elaine, Arkansas, 30 September to 1 October 1919, a massacre of Black sharecroppers organising a union, with estimates of 100 to 240 Black dead.

The Ku Klux Klan, refounded by William Joseph Simmons in 1915, was beginning the membership surge that would peak at around 4 million by 1925.

The Spanish flu pandemic (1918 to 1919) killed around 675,000 Americans, more than the country lost in the war.

The Red Scare

The Bolshevik Revolution in Russia (October 1917) and the German Revolution (November 1918) generated American fears of communist subversion. A series of anarchist letter bombs in April and June 1919, including one that damaged Attorney General A. Mitchell Palmer's house in Washington on 2 June, gave Palmer the pretext for action.

The Palmer Raids (November 1919 and January 1920) arrested around 10,000 suspected radicals, often without warrants. Around 556 foreign-born radicals were deported, including Emma Goldman to Soviet Russia on the USS Buford on 21 December 1919.

The Scare collapsed in 1920 when Palmer's prediction of a May Day revolution did not materialise.

The impact of the war

The United States entered World War I in April 1917 and mobilised around 4 million men. American casualties were around 116,000 dead. The Selective Service Act, the Espionage Act (1917), and the Sedition Act (1918) had created a new federal apparatus of conscription, censorship, and prosecution of dissent.

The war had vastly accelerated American economic and political power. By 1919 the United States held around half the world's gold reserves and was the world's largest creditor.

Wilson and Versailles

Wilson sailed for Paris on 4 December 1918 with his Fourteen Points (8 January 1918), the most influential of which was the call for a League of Nations. The Treaty of Versailles was signed on 28 June 1919.

The Senate, controlled by Republicans, refused to ratify without the Lodge Reservations on Article X (collective security). Wilson refused compromise; his September 1919 speaking tour to rally support ended with a stroke on 2 October 1919. The Senate rejected the Treaty on 19 November 1919 (53 to 38 against) and again on 19 March 1920. The United States made a separate peace with Germany on 25 August 1921.

The rejection set the United States on its 1920s and 1930s course of unilateral internationalism without the League.

The crises of 1919 at a glance

How to read a source on this topic

Section II sources on 1919 are usually newspaper extracts, political cartoons, government statements (Palmer on the raids), photographs of strikes or riots, or extracts from Wilson's speeches and his opponents. Three reading habits.

First, ask who is afraid of whom. The dominant emotion of 1919 is fear: of Bolshevism, of immigrants, of Black assertiveness, of strikes. A source defending the Palmer Raids is manufacturing and exploiting that fear; a source from a deported radical or a Black newspaper reports the cost of it. Identify the source's stake in the panic.

Second, place the source on the 1919 calendar. The Treaty fight peaks in November; the riots cluster in the summer; the raids run November to January. A source's date tells you which crisis it speaks to and what the author already knew.

Third, separate event from interpretation. A photograph of the Chicago riot is evidence of violence; a caption blaming "Bolshevik agitators" is interpretation. Strong source answers read both layers and judge usefulness accordingly.

Model exam responses

A. Source response (5 marks). Source: a September 1919 cartoon from a conservative newspaper showing a hulking, bomb-carrying figure labelled "Bolshevism" looming over a frightened Uncle Sam, captioned "Shall this menace rule America?" Assess its usefulness for a historian studying the United States in 1919.

The cartoon is conservative anti-radical propaganda from the height of the strike wave, so its purpose is to equate organised labour and immigrant radicals with violent revolution rather than to record events. That makes it highly useful as evidence of the mood of the First Red Scare: the deliberate conflation of strikes with Bolshevism, the personification of dissent as a foreign monster, and the appeal to a frightened "Uncle Sam" capture exactly the climate that produced the Palmer Raids of November 1919. It is far less useful for the reality behind the panic - the around 4 million workers who struck over a 15 per cent rise in living costs, not over revolution, and whose disputes (Seattle, Boston, the Great Steel Strike) were defeated. Read critically, the cartoon is strong evidence for how fear was manufactured in 1919, and weak - indeed misleading - on the genuine economic grievances driving the strikes.

Marker's note: a top response states origin and purpose, separates what the source is useful FOR (the manufactured fear) from what it conceals (the real economic causes), anchors this in specific dated own knowledge, and ends in a judgement rather than describing the image.

B. Essay paragraph (from a 25-mark response on whether 1919 was a turning point in American history).

The clearest sign that 1919 was a turning point lies in America's retreat from the world it had just helped to remake. Woodrow Wilson returned from Paris with the League of Nations as the keystone of his Fourteen Points, yet his own Senate dismantled the project within the year. Republicans, who had captured both houses in November 1918, distrusted Article X's pledge of collective security; Henry Cabot Lodge would ratify only with reservations guarding Congress's war powers. Wilson refused to compromise, carried his case to the public, and collapsed with a stroke on 2 October 1919 - so that the Senate rejected the Treaty on 19 November 1919 and again on 19 March 1920, and the United States made a separate peace with Germany in 1921. As John Milton Cooper argues, Wilson's physical breakdown, as much as partisan hostility, sealed the defeat, lending the outcome a sharp contingency. The decision turned the world's most powerful economy inward for two decades, making 1919 the hinge on which American internationalism swung shut.

Marker's note: the paragraph argues a single proposition (1919 as the turning point in foreign policy), supports it with dated specifics, and uses a historian (Cooper) to deepen the argument rather than decorate it. Sustained argument plus historiography is what lifts a paragraph into Band 6.

Command words and weaving historiography

Read the verb first. "Assess" and "Account for" want the conditions of 1919 WEIGHED and ranked, not listed; "To what extent / Evaluate" want a JUDGEMENT defending a thesis (was 1919 really a turning point?); "Assess the usefulness/reliability" of a source wants ORIGIN, MOTIVE and PERSPECTIVE, then a verdict. For source questions on 1919, run O-M-P-U: Origin, Motive, Perspective, then Usefulness/limitation - and always ask whether the source is stoking the Red Scare panic or reporting its cost. Weave historians as a clash, not a list: set Ann Hagedorn's "single convulsion of fear" against John Milton Cooper's stress on contingency (Wilson's stroke), or Cameron McWhirter's racial watershed against David Kennedy's wartime structures, then say which carries more weight and why. One historian used in genuine tension beats five name-dropped.

Historiography

David Kennedy (Over Here, 1980) is the standard study of the impact of the war on American society.

John Milton Cooper (Woodrow Wilson, 2009) is the major biography arguing Wilson's stroke, not Senate hostility, doomed the Treaty.

Cameron McWhirter (Red Summer, 2011) is the standard account of the 1919 racial violence.

Ann Hagedorn (Savage Peace, 2007) integrates the Red Scare, Red Summer, and Treaty fight into a single 1919 narrative.

Common exam traps

Treating 1919 as a year of peace and prosperity: It was a year of strikes, race riots, deportations, and a failed treaty.
Forgetting the Senate rejection date: 19 November 1919 (first vote) and 19 March 1920 (second).
Conflating the Red Scare with McCarthyism: The First Red Scare (1919 to 1920) ended with Palmer's failed May Day prediction; McCarthy belongs to the 1950s.

In one sentence

In 1919 the United States was the world's largest economy and a victorious power, but it was also gripped by labour conflict (4 million strikers), racial violence (the Red Summer, with 38 dead at Chicago), the Red Scare (Palmer Raids of November 1919 and January 1920), and the Senate's rejection of the Treaty of Versailles (19 November 1919), which together set the conservative and isolationist pattern of the 1920s.

Examples in context

Example 1. The 1919 strike wave and the Boston police strike. Approximately four million American workers struck in 1919. The Boston police strike (September 1919) and Calvin Coolidge's response ("there is no right to strike against the public safety") shaped his national reputation. David Kennedy (Over Here, 1980) and Robert Murray (Red Scare, 1955) integrate the labour crisis with the post-war Red Scare.

Example 2. The Palmer Raids (November 1919 to January 1920). Attorney General Mitchell Palmer's raids arrested around 10,000 alleged radicals; over 500 were deported, including Emma Goldman. Beverly Gage (The Day Wall Street Exploded, 2009) places the raids in the wider context of 1919 anarchist violence. The League of Nations rejection on 19 March 1920 completed the Wilsonian retreat.

foundation3 marksOutline the main economic problems facing the United States in 1919.

Show worked solution →

A 3-mark "outline" wants three distinct, dated problems, each in a sentence.

The end of the wartime boom: War contracts were cancelled and gross national product fell as the economy demobilised; around 4 million troops returned to the labour force.
Inflation and the cost of living: Inflation ran at around 15 per cent in 1919 and the cost of living roughly doubled between 1914 and 1920, squeezing wages and feeding industrial unrest.
A wave of strikes: Around 4 million workers struck in over 3,600 disputes (the Seattle General Strike in February, the Boston Police Strike in September, the Great Steel Strike from September), all defeated.
Marking criteria: 1 mark each for three distinct, correctly described economic problems; do not drift into the Red Scare or race riots, which are social.

foundation4 marksExplain the causes and consequences of the First Red Scare of 1919 to 1920.

Show worked solution →

A 4-mark "explain" needs a cause-and-effect chain with specific dated detail.

Causes: The Bolshevik Revolution (October 1917) and German Revolution (November 1918) raised fears of communist subversion; the 1919 strike wave was read as Bolshevism; and anarchist letter bombs in April and June 1919 (one damaged Attorney General A. Mitchell Palmer's house on 2 June) gave a pretext for action.
The response: The Palmer Raids (November 1919 and January 1920) arrested around 10,000 suspected radicals, often without warrants; around 556 foreign-born radicals were deported, including Emma Goldman on the USS Buford (21 December 1919).
Consequences: Civil liberties were trampled and organised labour was weakened, but the Scare collapsed in 1920 when Palmer's predicted May Day revolution failed to appear, discrediting him.
Marking criteria: 1 mark for a cause (fear of revolution/strikes/bombs); 1 mark for the raids and a figure; 1 mark for deportation detail; 1 mark for the consequence/collapse.

core5 marksSource A (paraphrased, owned): In a January 1920 public statement defending the raids, the Attorney General warned that an alien radical conspiracy, "licking at the altars of the churches" and "crawling into the sacred corners of American homes," was plotting to overthrow the government, and that decisive federal action had saved the Republic from revolution. Using Source A and your own knowledge, explain the political climate of the United States in 1919 to 1920. [5 marks]

Show worked solution →

A 5-mark "explain ... using the source" wants the source decoded for its perspective, then linked to own knowledge.

Decode the source: The vivid religious and domestic imagery ("altars," "sacred corners of American homes") is deliberate fear-mongering: Palmer casts dissent as a foreign contagion invading the American home, justifying mass arrests by inflating the threat. The source reveals the climate of moral panic, not its reality.
What this reflects (own knowledge): The First Red Scare (1919 to 1920) grew from the Bolshevik Revolution, a 4-million-strong strike wave portrayed as Bolshevism, and the 1919 letter bombs. The Palmer Raids arrested around 10,000 people and deported over 500, including Emma Goldman.
The outcome: The climate of nativist suspicion fed into the 1920s: the second Klan surged, immigration restriction gathered support, and America turned inward, completing the retreat marked by the Senate's rejection of the Treaty of Versailles.
Marking criteria: 1 mark for reading the source's fear-mongering perspective; 1-2 marks for own knowledge of the Red Scare and Palmer Raids; 1 mark for linking the strikes/bombs as causes; 1 mark for the wider climate (nativism, isolationism).

core6 marksSource B (paraphrased, owned): A modern historian of 1919 argues that the year's strikes, deportations and race riots were not separate crises but a single convulsion - a nation, exhausted by war and frightened by revolution abroad, turning its fear inward against radicals, immigrants and African Americans alike. Using Source B and your own knowledge, assess the usefulness of this interpretation for understanding the United States in 1919. [6 marks]

Show worked solution →

A 6-mark "assess the usefulness" question rewards origin/perspective plus own knowledge, ending in a judgement.

Perspective: Source B is a recent integrative interpretation - the position of Ann Hagedorn (Savage Peace, 2007), who reads 1919 as one connected crisis of fear. It is useful because it explains why so many upheavals clustered in a single year: a common engine of post-war anxiety.
Corroboration from own knowledge: The record supports the link: the 4-million-strong strike wave was branded Bolshevism; the Palmer Raids (around 10,000 arrests) targeted immigrant radicals; and the Red Summer (at least 25 riots, 38 dead in Chicago) hit returning Black veterans and Great Migration arrivals. The same nativist fear runs through all three.
Limitation: Reading 1919 as one fear can flatten distinct causes: the race riots grew from the Great Migration and labour competition, not chiefly from anti-Bolshevism, and the Treaty's rejection owed much to constitutional and partisan struggle (Lodge, Wilson's stroke) rather than mass panic.
Judgement: Highly useful for capturing the shared mood and the interconnection of the crises, but it must be supplemented with the specific causes of each - especially the racial and the constitutional - that a single "fear" thesis can obscure.
Marking criteria: 1 mark for identifying the integrative perspective (Hagedorn); 2 marks for own knowledge corroborating the link (strikes, raids, riots); 1-2 marks for a genuine limitation; 1 mark for a judgement on usefulness.

core5 marksExplain why the United States Senate rejected the Treaty of Versailles in 1919 and 1920.

Show worked solution →

A 5-mark "explain why" wants a causal account with dated evidence, not a narrative of the war.

Partisan control of the Senate: Republicans had won both houses in November 1918, so ratification (needing a two-thirds majority) depended on a Senate hostile to a Democratic President.
The objection to Article X: Senator Henry Cabot Lodge led the "reservationists," who feared that the League's collective-security clause (Article X) would commit the US to foreign wars without Congress's consent. They would ratify only with reservations.
Wilson's refusal to compromise: Wilson rejected the Lodge Reservations outright and took his case to the public on a September 1919 speaking tour, which ended in a debilitating stroke on 2 October 1919, removing him from effective leadership.
The votes: With neither side yielding, the Senate rejected the Treaty on 19 November 1919 (53 to 38) and again on 19 March 1920. The US made a separate peace with Germany on 25 August 1921.
Marking criteria: 1 mark for partisan/two-thirds context; 1 mark for Article X and Lodge; 1-2 marks for Wilson's intransigence and stroke; 1 mark for the dated votes and separate peace.

exam25 marksTo what extent was 1919 a turning point in the history of the United States?

Show worked solution →

This is an extended-response/essay. Markers reward a sustained, evidence-based argument that addresses "to what extent" directly and weaves in historiography - not a narrative.

Band-6 PLAN

Thesis. 1919 was a decisive turning point in that it ended the Progressive Era and Wilsonian internationalism and inaugurated the conservative, nativist and isolationist 1920s; but it was a turning point that confirmed and accelerated existing trends (racial division, anti-radicalism, economic dominance) rather than creating them from nothing. It was the hinge of the era, not its sole cause.
Argument 1 - The internationalist turning point (strong case for "turning point"). The Senate's rejection of the Treaty of Versailles (19 November 1919; again 19 March 1920) and Wilson's collapse killed American membership of the League and set the unilateralist course of the interwar decades. Evidence: Lodge's reservations on Article X; Wilson's stroke (2 October 1919); the separate peace of 25 August 1921.
Argument 2 - The domestic conservative turn (continuity within change). The strike wave (4 million workers), the Palmer Raids and the Red Scare broke organised labour and licensed the nativism that produced 1920s immigration restriction and the second Klan. But these built on pre-war anti-radicalism and the wartime Espionage and Sedition Acts (1917 to 1918), so 1919 intensified an existing trajectory.
Argument 3 - The racial reckoning (a turning point deferred). The Red Summer (at least 25 riots; 38 dead at Chicago; the Elaine massacre) marked African Americans' new militancy after the Great Migration and war service ("the New Negro"), yet the violence entrenched segregation rather than overturning it; the real turning point in civil rights lay decades ahead. 1919 changed the terms of the struggle more than its outcome.
Historiography. David Kennedy (Over Here, 1980) frames 1919 within the war's transformation of American society and the state. Ann Hagedorn (Savage Peace, 2007) reads the year as a single connected convulsion of fear, supporting a strong "turning point" reading. Cameron McWhirter (Red Summer, 2011) centres the racial violence as a watershed in Black consciousness, while John Milton Cooper (Woodrow Wilson, 2009) stresses contingency, arguing Wilson's stroke rather than deep structure doomed the Treaty.
Judgement. Weigh the decisive internationalist break (Hagedorn, the Treaty votes) against the continuities Kennedy and McWhirter expose: 1919 was the clearest hinge of the era - it locked in isolationism and conservatism - but it accelerated forces already in motion rather than originating them. A qualified "yes."

MODEL PARAGRAPH (Argument 1)

The strongest case for treating 1919 as a turning point lies in the collapse of American internationalism. Woodrow Wilson had sailed for Paris in December 1918 carrying his Fourteen Points and the promise of a League of Nations, yet within a year his own Senate had destroyed the project. Republicans, who had won both houses in November 1918, distrusted Article X's commitment to collective security; Senator Henry Cabot Lodge would ratify only with reservations protecting Congress's war powers. Wilson refused to bend, took his case to the country, and suffered a disabling stroke on 2 October 1919 - so that when the Senate voted on 19 November 1919, and again on 19 March 1920, the Treaty failed, and the United States made a separate peace with Germany in 1921. As John Milton Cooper argues, it was Wilson's physical collapse as much as Senate hostility that doomed compromise; the contingency of a single illness helped fix two decades of American policy. The decision turned the world's greatest power away from the international order it had helped design, setting the isolationist pattern that held until 1941.

Marker's note. A band-6 response keeps "to what extent" in view throughout - ranking the genuinely new (the internationalist break) against the continuities (anti-radicalism, racial division it accelerated rather than began) - anchors every claim in dated evidence, sets at least two historians in genuine tension (Hagedorn's convulsion vs Cooper's contingency; McWhirter's racial watershed), and reaches a graded judgement. Listing 1919's crises without weighing whether they originated or merely accelerated change caps the response in the middle bands.
