Start free practice exam →Studying for the DSST Civil War and Reconstruction exam? Good move – this is one of the most-taken history DSSTs because it pulls double duty as both a U.S. history credit and an upper-level humanities credit at many programs. The exam runs about 100 multiple-choice questions in 90 minutes.
Content splits roughly into thirds: causes of the war (slavery, sectionalism, the breakdown of compromise), the war itself (1861 through Appomattox), and Reconstruction (the political and social reshaping of the South from 1865 to 1877). Don’t overlook Reconstruction – about a quarter of the exam sits there, and it’s where most test-takers underprepare.
The Petersons outline groups the exam into four roughly equal topic areas. If you can keep dates, key figures, and the cause-and-effect chain straight, you’ll be in good shape on test day.
Slavery sits at the center of every causal story, but the exam expects you to understand the political and economic structure around it. Know the major compromises and what each one tried to settle: the Missouri Compromise of 1820, the Compromise of 1850 (and the Fugitive Slave Act it included), and the Kansas-Nebraska Act of 1854.
Be familiar with the Dred Scott v. Sandford decision (1857) and how it inflamed Northern opinion, John Brown’s raid on Harpers Ferry (1859), and the formation of the Republican Party as a free-soil response. The election of 1860 is essential: Lincoln won without a single Southern electoral vote, which triggered South Carolina’s secession in December 1860 and the cascade that followed.
Underlying themes the test loves to probe: economic differences (industrial North vs. agricultural South), tariffs and the question of who controlled federal economic policy, and the doctrine of states’ rights versus federal supremacy.
The war opens with Fort Sumter in April 1861. Lincoln calls for 75,000 volunteers; the upper South (Virginia, North Carolina, Tennessee, Arkansas) secedes; the border states (Maryland, Kentucky, Missouri, Delaware) stay in the Union with varying levels of internal conflict.
Key battles you’ll need to know: First Bull Run / First Manassas (July 1861, Confederate victory that disabused Northerners of a quick war), Shiloh (April 1862, brutal Union victory in the West), the Peninsula Campaign (McClellan’s slow march on Richmond), and Antietam (September 1762, the bloodiest single day in American history and a strategic Union win that gave Lincoln the political cover to issue the Emancipation Proclamation).
The Emancipation Proclamation (effective January 1, 1863) didn’t free enslaved people in Union-held areas, but it redefined the war’s political purpose and discouraged European recognition of the Confederacy. Know the difference between what it actually did versus what it’s remembered for.
1863 is the war’s turning point. Gettysburg (July 1-3, 1863) was the largest battle ever fought in the Western Hemisphere and broke Lee’s last serious offensive into the North. Vicksburg fell to Grant on July 4, 1863, splitting the Confederacy along the Mississippi. Together these two simultaneous victories marked the war’s strategic inflection point.
Lincoln promotes Grant to overall Union command in 1864 and pursues a strategy of total war: continuous, attritional pressure on multiple fronts. Sherman’s March to the Sea (November-December 1864) cut a swath from Atlanta to Savannah and broke the South’s economic and psychological will to fight. Petersburg falls in April 1865; Lee surrenders to Grant at Appomattox Court House on April 9, 1865.
Lincoln is assassinated by John Wilkes Booth at Ford’s Theatre on April 14, just five days after Appomattox. Andrew Johnson becomes president and inherits a fraught Reconstruction. Know Lincoln’s Second Inaugural (“with malice toward none”) and what it suggests about the path he might have taken.
This is where many test-takers underprepare. Three phases worth knowing distinctly:
Presidential Reconstruction (1865-1867): Andrew Johnson’s lenient approach. Southern states pass “Black Codes” restricting freed people’s rights. Congress responds with the 13th Amendment (abolishing slavery), the Civil Rights Act of 1866 (over Johnson’s veto), and the 14th Amendment (citizenship and equal protection).
Radical / Congressional Reconstruction (1867-1877): Congress takes control with the Reconstruction Acts of 1867, divides the South into five military districts, and requires ratification of the 14th Amendment as a condition of readmission. The 15th Amendment (1870) protects voting rights regardless of race. Johnson is impeached in 1868 (acquitted by one vote in the Senate).
The end of Reconstruction (1877): The disputed Hayes-Tilden election of 1876 is resolved by the Compromise of 1877: Hayes becomes president; in exchange, the last federal troops are withdrawn from the South. “Redeemer” Democrats reclaim power; Jim Crow segregation and disenfranchisement follow.
Major institutions: the Freedmen’s Bureau (education, labor contracts), sharecropping (the economic substitute for slavery that trapped many freed people), and the rise of organized white supremacist violence (Ku Klux Klan, founded 1865).
Correct Answer: B. Repealing the Missouri Compromise and allowing popular sovereignty in Kansas and Nebraska
Explanation: The Kansas-Nebraska Act, championed by Stephen Douglas, replaced the Missouri Compromise line with popular sovereignty – letting territorial residents decide on slavery themselves. It triggered “Bleeding Kansas,” the violent struggle that previewed the Civil War. Option A describes the Missouri Compromise itself; option C describes parts of the Compromise of 1850.
Correct Answer: B. African Americans (whether enslaved or free) were not and could not be U.S. citizens, and that Congress had no power to ban slavery in the territories
Explanation: Chief Justice Taney’s majority opinion held both that African Americans had no standing to sue in federal court and that the Missouri Compromise’s ban on slavery in northern territories was unconstitutional. The decision galvanized Northern opposition and made compromise increasingly impossible.
Correct Answer: C. Confederate forces firing on Fort Sumter in April 1861
Explanation: The bombardment of Fort Sumter in Charleston Harbor on April 12, 1861, is by convention the start of the war. Secession (option A) preceded it; First Bull Run (option D) was the first major land battle a few months later. Lincoln’s inauguration was important politically but not the war’s opening.
Correct Answer: B. It was a strategic Union victory that gave Lincoln political cover to issue the Emancipation Proclamation
Explanation: Antietam was a tactical draw but a strategic Union win – it stopped Lee’s invasion of the North. Lincoln had been waiting for a Union victory to issue the Emancipation Proclamation, which he announced five days after the battle. The Mississippi (option D) was opened by Vicksburg in 1863.
Correct Answer: B. It freed enslaved people only in Confederate-held territory, leaving slavery legal in border states and Union-occupied areas
Explanation: The proclamation applied only to states “in rebellion,” which Lincoln justified as a war measure under his constitutional authority as commander-in-chief. The 13th Amendment (1865) abolished slavery nationally as a constitutional matter (option C).
Correct Answer: B. It split the Confederacy along the Mississippi River and gave the Union control of the river
Explanation: Grant’s long siege of Vicksburg ended on July 4, 1863 – one day after Gettysburg ended in the East. Union control of the Mississippi cut off Confederate states west of the river (Texas, Arkansas, Louisiana) from the rest of the Confederacy and crippled their ability to move troops and supplies.
Correct Answer: B. It demonstrated the strategy of total war by destroying the South’s economic infrastructure and civilian morale
Explanation: Sherman cut a 60-mile-wide swath from Atlanta to Savannah, destroying railroads, factories, and food stores to break the South’s will and capacity to fight. It’s a textbook example of total war – military operations aimed not just at enemy armies but at the entire war-supporting society.
Correct Answer: A. Abolished slavery, granted citizenship and equal protection, and protected voting rights regardless of race
Explanation: 13th (1865) abolished slavery, 14th (1868) granted citizenship and equal protection, 15th (1870) protected voting rights regardless of race, color, or previous condition of servitude. Option B describes early-20th-century Progressive Era amendments.
Correct Answer: B. To provide aid, education, and assistance with labor contracts for newly freed people and impoverished Southerners
Explanation: The Bureau of Refugees, Freedmen, and Abandoned Lands (typically just “Freedmen’s Bureau”) provided food, clothing, schooling, medical care, and help negotiating fair labor contracts. It was the federal government’s primary post-war effort to support freed people and is credited with founding many historically Black colleges and universities.
Correct Answer: B. The Compromise of 1877 resolved the disputed Hayes-Tilden election by withdrawing federal troops from the former Confederate states
Explanation: The 1876 election between Hayes (R) and Tilden (D) was contested. The Compromise of 1877 awarded the presidency to Hayes; in exchange, the last federal troops left the South. With military protection gone, “Redeemer” Democrats reclaimed power and erected the Jim Crow system. Note: Johnson (option D) was impeached but acquitted by one vote in 1868.

Textbooks are great as far as they go, but I’d generally recommend you opt for this exam guide instead. It tends to cut through the confusion and help you accelerate your learning process.
Ok, so the DSST website isn’t the most inviting, but it will give you the best approximation of the real exam experience. Also, the official practice test is quite affordable (currently just $5 per practice exam).
Though the design is now quite dated, InstantCert is one of the OGs in the space. They offer flashcards to study for the exam, but their coverage is somewhat limited and I'm not sure whether they use spaced repetition or other modern study science.
