What caused the Civil War?

The central cause was slavery, above all whether it would expand into the new western territories, tangled with the argument over states' rights. By the 1850s the industrial, antislavery North and the agricultural, slaveholding South had split into hostile sections. A string of compromises failed (the Missouri Compromise, the Compromise of 1850, the Kansas-Nebraska Act), and inflaming events (Dred Scott in 1857, John Brown's raid on Harpers Ferry in Virginia in 1859) deepened the crisis. When Abraham Lincoln, who opposed slavery's expansion, won the election of 1860 without any Southern electoral votes, Southern states seceded and formed the Confederacy.

What did the three Reconstruction Amendments do?

The 13th Amendment (1865) abolished slavery throughout the United States. The 14th Amendment (1868) granted citizenship to all persons born or naturalized in the country and guaranteed equal protection of the laws. The 15th Amendment (1870) prohibited denying the right to vote based on race, color, or previous condition of servitude, giving African American men the vote. Match each to its specific guarantee: freedom, citizenship and equal protection, and voting rights. The 14th Amendment's equal-protection clause later became the legal foundation of the 20th-century civil rights movement.

How was Reconstruction reversed?

Reconstruction ended with the Compromise of 1877, which settled the disputed 1876 election and withdrew the last federal troops from the South. Without federal protection, white Southern Democrats regained power and dismantled African Americans' gains. They imposed Jim Crow segregation in schools, transportation, and public facilities, and disenfranchised Black men through poll taxes, literacy tests, and grandfather clauses, plus intimidation and violence. In Plessy v. Ferguson (1896) the Supreme Court upheld separate but equal, giving segregation legal cover until Brown v. Board of Education overturned it in 1954.

How did the settlement of the West affect American Indians?

Settlement devastated American Indian peoples. The transcontinental railroad and the Homestead Act drew waves of settlers onto the Plains. The bison, on which Plains Indians depended for food, clothing, and shelter, were slaughtered nearly to extinction, destroying their way of life. A series of conflicts ended with American Indians defeated and confined to reservations. Federal policy then forced assimilation: the Dawes Act (1887) broke up tribal lands into individual family plots, costing American Indians most of their land and pressuring them to abandon their cultures. By 1890 the frontier was declared closed.

What Module 3 actually demands

Module 3 is the hinge of American history: the Union breaks apart over slavery, fights the Civil War, and then struggles through Reconstruction to define freedom, only to see those gains reversed by Jim Crow, while the West is settled at devastating cost to American Indians. The Enduring Issues here are inequality and human rights (slavery, freedom, segregation), conflict (war), and power (federal versus state). Virginia is central: it was the Confederate heartland, Richmond was the Confederate capital, and the war ended at Appomattox.

This guide ties together the matching dot-point pages, each with its own worked questions: sectionalism and the coming of the Civil War, the Civil War, the Emancipation Proclamation and the Gettysburg Address, Reconstruction and its amendments, the end of Reconstruction and Jim Crow, and the closing of the frontier and American Indians.

Sectionalism and the causes of the war (VUS.6, VUS.7)

The North (industrial, antislavery) and South (plantation, slaveholding) split over slavery, especially its expansion into the territories, with states' rights as the framing. Compromises failed (Missouri, 1850, Kansas-Nebraska); Dred Scott (1857) and John Brown's raid on Harpers Ferry, Virginia (1859) inflamed both sides; and Lincoln's election in 1860 triggered secession and the Confederacy.

The Civil War (VUS.7)

The Union had more factories, people, railroads, and a navy; the Confederacy fought defensively with strong leadership (Lee). The turning point was July 1863: Gettysburg stopped Lee's invasion and Vicksburg split the Confederacy. The war ended at Appomattox, Virginia (April 1865).

Lincoln's words (VUS.7)

The Emancipation Proclamation (1863) declared the enslaved in the Confederacy free, reframing the war as a fight against slavery (full abolition came with the 13th Amendment). The Gettysburg Address tied the war to liberty, equality, and self-government.

Reconstruction and its reversal (VUS.7, VUS.8)

Reconstruction produced the 13th, 14th, and 15th Amendments and the Freedmen's Bureau, and African Americans voted and held office. But the Compromise of 1877 withdrew federal troops, and Jim Crow segregation, disenfranchisement (poll taxes, literacy tests, grandfather clauses), and Plessy v. Ferguson (1896) rolled back the gains. Washington and Du Bois offered contrasting responses.

The West (VUS.8)

The railroads and the Homestead Act drew settlers; the bison were destroyed; American Indians were defeated, confined to reservations, and subjected to forced assimilation by the Dawes Act (1887). By 1890 the frontier was declared closed.

Module 3 of the Virginia and US History SOL covers the Civil War era: sectionalism and the causes of the war (slavery and its expansion, failed compromises, Dred Scott, Lincoln's 1860 election, and secession); the war (Union versus Confederate advantages, Lincoln, Grant, Lee, and Davis, the Gettysburg-Vicksburg turning point of 1863, and the surrender at Appomattox in Virginia); the Emancipation Proclamation and the Gettysburg Address; Reconstruction's three amendments (13th abolished slavery, 14th granted citizenship and equal protection, 15th protected the vote) and the Freedmen's Bureau; the end of Reconstruction (the Compromise of 1877), Jim Crow segregation, disenfranchisement, Plessy v. Ferguson, and the responses of Washington and Du Bois; and the settlement of the West (railroads, the Homestead Act, the destruction of the bison, and the Dawes Act).

Solutions

Q1: Slavery, especially whether it could expand into the new western territories (tied to states' rights).
Q2: It ruled that African Americans were not citizens and that Congress could not ban slavery in the territories, implying slavery could spread anywhere and the government could not stop it.
Q3: Union: more factories, population, railroads, or a navy. Confederacy: defensive home-ground war, strong leadership (Lee), or motivation.
Q4: It stopped Lee's invasion of the North and, with Vicksburg, marked the turning point after which the Confederacy declined.
Q5: At Appomattox Court House, Virginia, in April 1865, when Lee surrendered to Grant.
Q6: It declared enslaved people in the rebelling Confederate states free, making the war a fight against slavery; it did not free those in the loyal border states or abolish slavery nationwide (the 13th Amendment did).
Q7: 13th: abolished slavery. 14th: citizenship and equal protection. 15th: the vote regardless of race.
Q8: The Compromise of 1877 settled the disputed 1876 election and withdrew the last federal troops from the South, ending federal protection of freed people's rights.
Q9: That "separate but equal" segregation was constitutional, legalizing Jim Crow.
Q10: To give settlers free or cheap western land (up to 160 acres) if they lived on and farmed it for several years.
