The US Civil War and Reconstruction: Practice Questions

These are original questions written for Marlbridge, for revision and practice on this content. They are not reproduced past-paper questions. The wording and exact sources below are invented for practice purposes, but the structure follows the syllabus’s own: on Paper 1, Core Content questions are three-part structured essays, split (a), (b), (c); on Paper 2, one document question with up to seven sources is set on a single prescribed Core Content topic. Cambridge International holds copyright in its own papers; use these alongside the official past papers available through your school or Cambridge directly.

These questions cover key question 1.4 of Cambridge IGCSE 0470 and O Level 2147: why there was a civil war in the United States and what its results were. The question is the prescribed Paper 2 topic for the November 2025 and June 2026 series, so Question 3 practises the source skills. The short sources in Question 3 are genuine extracts from documents of the period; the questions on them are original.

Paper 1 style: Structured Questions

Question 1: Slavery and the coming of war

(a) Describe the Compromise of 1850. [4]

(b) Why did the Kansas–Nebraska Act of 1854 increase tension between North and South? [6]

(c) ‘Slavery was the main cause of the American Civil War.’ How far do you agree with this statement? Explain your answer. [10]

Worked answer

(a) Any four points: California was admitted as a free state; the territories of New Mexico and Utah would decide on slavery by popular sovereignty; the slave trade (but not slavery) was abolished in the District of Columbia; a stricter Fugitive Slave Act required Northern officials and citizens to help return people who had escaped slavery; it followed the Mexican War, which had raised the question of slavery in the new lands. [4]

(b) Explained reasons, for example: the Act let the settlers of Kansas and Nebraska decide on slavery, which repealed the Missouri Compromise ban north of 36°30′, so Northerners felt the South was breaking a settled agreement; pro- and anti-slavery settlers rushed into Kansas and fought (“Bleeding Kansas”), showing the issue could no longer be settled peacefully; opponents of the Act founded the Republican Party, a purely Northern party, which divided national politics along sectional lines. Two well-explained reasons reach full marks. [6]

(c) Agree: every major crisis — 1820, 1850, 1854, 1857 (Dred Scott), 1859 (Harpers Ferry) — was about slavery and its expansion; Southern states’ own declarations of secession named the defence of slavery; Lincoln’s election mattered because he opposed slavery’s spread. Disagree / other factors: states’ rights and the Nullification Crisis show a constitutional argument; economic differences and tariffs; the breakdown of compromise and the split in the Democratic Party in 1860; the trigger of Lincoln’s election and Fort Sumter. Judgement: the best answers argue that states’ rights and economic differences were largely about slavery, so slavery was the underlying cause and the 1860 election the trigger. Top-level answers explain both sides and reach a supported conclusion. [10]

Question 2: Victory and Reconstruction

(a) What advantages did the North have at the start of the war in 1861? [4]

(b) Why was the Emancipation Proclamation important to the Union’s war effort? [6]

(c) ‘Reconstruction was a failure.’ How far do you agree? Explain your answer. [10]

Worked answer

(a) Any four: a much larger population (about 22 million against about 9 million, over a third of whom were enslaved); most of the country’s factories; most of the railway network; a navy that could blockade Southern ports; greater food production; an established government and treasury. [4]

(b) Explained points: it turned the war into a war against slavery as well as for the Union, which made it very hard for Britain and France, both opposed to slavery, to recognise the Confederacy; it encouraged enslaved people to escape to Union lines, weakening the Southern economy; it allowed the recruitment of Black soldiers, about 180,000 of whom served in the Union army. [6]

(c) Agree: Black Codes and Ku Klux Klan terror; most freed people became sharecroppers without land; Northern commitment faded and the Compromise of 1877 withdrew federal troops; Southern states later used poll taxes, literacy tests and violence to stop Black men voting. Disagree: slavery was abolished by the 13th Amendment; the 14th and 15th Amendments wrote citizenship, equal protection and voting rights into the Constitution; Freedmen’s Bureau schools; Black Americans were elected to Congress, such as Hiram Revels in 1870; the Union was restored. Judgement: for example, a failure in securing equality in the short term, but a lasting success in ending slavery and creating constitutional rights that later civil rights campaigns used. [10]

Paper 2 style: Document Question

Topic: Why did the Southern states secede, 1860–61?

Source A — Abraham Lincoln, speech at Springfield, Illinois, June 1858: “A house divided against itself cannot stand. I believe this government cannot endure, permanently half slave and half free.”

Source B — from South Carolina’s declaration of the causes of its secession, December 1860, which complained of “an increasing hostility on the part of the non-slaveholding States to the institution of slavery”.

Source C — Alexander Stephens, Vice-President of the Confederacy, speech in Savannah, March 1861: “Our new government is founded upon exactly the opposite idea; its foundations are laid, its cornerstone rests, upon the great truth that the negro is not equal to the white man; that slavery, subordination to the superior race, is his natural and normal condition.”

Source D — Abraham Lincoln, letter to the newspaper editor Horace Greeley, August 1862: “My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery.”

(a) What can you learn from Source B about why South Carolina seceded? [4]

(b) Why do you think Southern leaders were alarmed by speeches such as Source A? [6]

(c) How far does Source C support Source B? [8]

(d) Does Source D prove that the war was not about slavery? Explain your answer. [7]

(e) ‘The Southern states seceded to defend slavery.’ How far do these sources support this view? [15]

Worked answer

(a) Source B shows that South Carolina blamed the free states’ growing hostility to slavery; it saw secession as a defence of slavery as an institution; it implies the state no longer trusted the federal government to protect it, given what had happened by December 1860 (Lincoln’s election). Developed inferences score more than copying. [4]

(b) Lincoln was the leading Republican; the speech suggested the nation would eventually become all free, which Southerners read as a threat to end slavery even where it existed. Once Lincoln won in 1860 without Southern votes, they feared he would act on it. Context (Republican opposition to slavery’s expansion) is needed for the higher marks. [6]

(c) Strong support: both put slavery at the centre; Source B complains of hostility to slavery, and Source C states that the Confederacy’s “cornerstone” is slavery and racial inequality. Source C goes further, as it is an open statement of the new government’s founding idea rather than a list of grievances. Both are Southern public statements, written to justify secession, which explains their agreement. [8]

(d) No. Source D shows Lincoln’s public war aim in August 1862 was to save the Union, and he was writing to reassure Northern and border-state opinion. But he was already preparing the Emancipation Proclamation, issued in preliminary form a month later, and Sources B and C show the South left the Union to protect slavery. The war’s purpose for the North and the cause of secession are different questions. [7]

(e) Support: Sources B and C directly name slavery as the reason for secession; Source A explains why the South feared the Republicans. Challenge: Source D suggests the North was fighting for the Union, not against slavery, in 1862; Source B’s wording also reflects a states’-rights grievance against other states. Evaluation: Sources B and C are official Southern statements, so they are strong evidence of Southern motives; Source D is about Northern aims, not Southern ones. Judgement: the sources strongly support the view. [15]

Where marks are usually lost

• Writing about the whole war when the question asks about one turning point or one source.
• Treating Source D as Lincoln’s private belief rather than a public letter written for a political purpose.
• Copying sources instead of making inferences from them.
• Mixing up the dates of emancipation (1863) and abolition (1865).

Frequently asked questions

How is IGCSE History 0470 Paper 1 structured? Paper 1 (2 hours, 60 marks, 40%) has Section A on the Core Content (eight questions, answer two) and Section B on the Depth Studies (two on each, answer one). Each question is a three-part structured essay worth 4, 6 and 10 marks.

How is Paper 2 structured? Paper 2 (1 hour 45 minutes, 40 marks, 30%) sets one five-part document question, with up to seven sources, on a prescribed Core Content topic that changes each series.

Do 0470 and 2147 share the same Core Content? Yes. For 2024–2026, Cambridge IGCSE History 0470 and O Level History 2147 have the same Core Content key questions, so these questions suit both; only the papers’ weightings and IGCSE’s third component differ.

What does the Kansas–Nebraska Act question test? Why the 1854 Act, by letting settlers decide on slavery, reopened the question of slavery in the territories and raised tension between North and South.
