Session 14: The Civil War & Reconstruction

Visual Study Cue

Use the image above as a map for this session. First identify the civics concept, historical event, economic model, geographic pattern, or source skill; then connect it to the evidence in the lesson.

Evidence Model

Use the second image for GED®-style reasoning: identify the source or data, decide what claim it supports, and eliminate answer choices that go beyond the evidence.

What You Will Learn
By the end of this session you will be able to explain the multiple causes of the Civil War, trace the war's major turning points, understand what the Emancipation Proclamation did and did not do, and evaluate why Reconstruction succeeded constitutionally but failed politically.

The Causes of the Civil War

Historians identify four intertwined causes — but slavery was the root of all of them:

1. Slavery
The fundamental cause. The Southern economy depended on enslaved labor for cotton, tobacco, and rice production. By 1860, enslaved people represented over $3 billion in "property" — more than all U.S. railroads and factories combined. Southerners feared that a Republican-controlled federal government would restrict or abolish slavery.

2. States' Rights
Southern states argued they had the right to leave the Union (secession) if the federal government threatened their institutions. This was the constitutional argument layered over the slavery dispute.

3. Economic Differences
The North was industrializing rapidly — factories, railroads, wage labor. The South was agricultural and dependent on slave-based plantation farming. They disagreed on tariffs (the North favored high tariffs to protect industry; the South, which imported manufactured goods, opposed them).

4. Sectionalism
Intense regional identity — loyalty to one's region over the nation — had been building for decades. Political compromises repeatedly papered over but never resolved the slavery question.

The Crisis Escalates: 1850–1860

Secession and the Formation of the Confederacy

Between December 1860 and June 1861, eleven Southern states seceded and formed the Confederate States of America, with Jefferson Davis as President. They argued the federal government had no authority to prevent secession.

The War Begins: Confederate forces fired on the federal Fort Sumter in Charleston, South Carolina (April 12–14, 1861), beginning the war.

Major Battles and Turning Points

The Emancipation Proclamation (January 1, 1863)

One of the most misunderstood documents in American history:

What it DID:

• Declared enslaved people in Confederate states currently in rebellion to be "forever free"
• Transformed the war's purpose — from preserving the Union to also abolishing slavery
• Authorized Black men to serve in the Union Army (180,000 served by war's end)
• Discouraged Britain and France from recognizing the Confederacy (neither wanted to be seen supporting slavery)

What it did NOT do:

• Did NOT free enslaved people in border states (Missouri, Kentucky, Maryland, Delaware) loyal to the Union — Lincoln couldn't risk losing them
• Did NOT immediately free anyone — it applied only to Confederate territory where the Union had no enforcement power (yet)
• Was a war measure, not a permanent law — actual abolition came with the 13th Amendment (1865)

Reconstruction (1865–1877)

After the war, the nation faced the question: on what terms would the South rejoin the Union, and what would freedom mean for 4 million formerly enslaved people?

The Reconstruction Amendments:

• 13th Amendment (1865) — abolished slavery throughout the United States
• 14th Amendment (1868) — granted citizenship to all born in the U.S.; equal protection and due process; overturned Dred Scott
• 15th Amendment (1870) — prohibited denying the vote based on race, color, or previous condition of servitude

Freedmen's Bureau (1865) — federal agency that established schools, hospitals, and labor contracts for formerly enslaved people; achieved significant results in education before being defunded.

Radical Reconstruction (1867–1877):

• Radical Republicans in Congress took control from President Johnson (whom they impeached in 1868, the first presidential impeachment)
• Divided the South into military districts with federal troops enforcing civil rights
• Black men voted and held office in significant numbers for the first time — 16 Black congressmen, 2 Black senators served during Reconstruction
• Southern states required to ratify the 14th Amendment to rejoin the Union

The Failure of Reconstruction

Reconstruction's constitutional achievements were real — but they were systematically dismantled:

• Black Codes — state laws restricting Black freedom (limiting movement, labor contracts, political rights)
• Ku Klux Klan — terrorist organization using violence and intimidation to suppress Black voting and civil rights
• Compromise of 1877 — to resolve the disputed 1876 presidential election, Republicans agreed to withdraw federal troops from the South; Reconstruction effectively ended
• Sharecropping — replaced slavery with a new economic system trapping Black farmers in perpetual debt
• Jim Crow laws — state-mandated racial segregation in all areas of public life; reinforced by Plessy v. Ferguson (1896)
• Disenfranchisement — poll taxes, literacy tests, grandfather clauses stripped Black men of the vote they had briefly held

Reconstruction's failure left the racial contradictions of American democracy unresolved until the Civil Rights Movement nearly a century later.

Key Terms

• Secession — the act of formally withdrawing from the Union
• Anaconda Plan — Union strategy to blockade Southern ports, control the Mississippi River, and economically strangle the Confederacy
• Total war — military strategy targeting not just enemy armies but also civilian infrastructure and morale
• Reconstruction — the period (1865–1877) of rebuilding the South and reintegrating former Confederate states into the Union
• Sharecropping — a labor system where farmers worked land owned by others in exchange for a share of the crop; kept many Black families in perpetual poverty and debt
• Impeachment — the formal charge of misconduct against a public official by the House of Representatives (President Johnson was impeached in 1868 but acquitted by one vote in the Senate)
