Topic 5.10 Notes – Reconstruction

Reconstruction was the fight over what Union victory would actually mean after the Civil War. From 1865 to 1877, the country had to decide how the former Confederate states would rejoin, what freedom would look like for formerly enslaved people, and whether the president or Congress would control that process.

What Reconstruction Changed

Emancipation destroyed slavery during the war, but it did not answer what rights freedpeople would have or how the South would be rebuilt. Reconstruction was the effort from 1865 to 1877 to restore the former Confederate states, define freedom, and settle who controlled reunion.

The core questions all connect:

  • Readmission meant deciding the terms for former Confederate states to return.
  • Freedpeople’s rights meant deciding whether freedom included voting, land, family control, education, and legal equality.
  • Federal vs. state power meant deciding whether states could still define rights mostly on their own.
  • Congress vs. president meant deciding who would run Reconstruction policy.

The biggest changes to lock in:

  • 13th Amendment permanently ended slavery.
  • Secession was effectively settled. States could not leave the Union.
  • Citizenship became more national, especially through the 14th Amendment.
  • The federal government took a bigger role in protecting rights.
  • The South saw a brief biracial democracy, with Black voting and officeholding.

The tension you need to remember is simple. Reconstruction changed the Constitution a lot, but daily life and economic power changed far less.

Competing Plans for Reconstruction

The first fight was over how harsh or lenient reunion should be.

Lincoln’s Ten Percent Plan

Lincoln’s Proclamation of Amnesty and Reconstruction in 1863 offered a quick path back. If 10 percent of a state’s 1860 voters swore loyalty and accepted emancipation, they could rebuild a state government. Lincoln wanted fast restoration, but this plan gave no broad protection for Black suffrage or long-term rights.

Wade-Davis Bill

Congress thought Lincoln was too lenient. The Wade-Davis Bill required a majority to take an ironclad oath saying they had never supported the Confederacy. Lincoln pocket-vetoed it. That clash previewed the larger Congress-versus-president struggle.

Johnson’s Presidential Reconstruction

Andrew Johnson kept reunion easy. Southern states had to repeal secession, repudiate Confederate debt, and ratify the 13th Amendment. He handed out pardons widely, did not require Black voting rights, and let former Confederates return to office, including Alexander Stephens.

Black Codes

Southern governments then passed Black Codes to control freedpeople through labor contracts, vagrancy laws, apprenticeship laws, and limits on movement, property, testimony, and arms. Mississippi’s Black Code is the standard example. These laws convinced many northerners that Johnson’s plan had failed, which is exactly the argument this cartoon makes about violence and white southern resistance under Johnson’s approach.

How the Federal Government Tried to Protect Freedom

Freedpeople defined freedom in concrete ways. They wanted legal marriages, control of family life, independent churches, schools, land, and political participation.

Freedmen’s Bureau

The Freedmen’s Bureau was created in 1865 as the Bureau of Refugees, Freedmen, and Abandoned Lands and led by Oliver O. Howard. It gave food, medical care, legal help, marriage legalization, labor contract supervision, and school support. It helped found schools and HBCUs, including Howard University. Its limits mattered too. It was understaffed, uneven, and could not deliver lasting land reform. The promise of “forty acres and a mule” came from Sherman’s Special Field Order No. 15, but Johnson returned much land to former Confederates.

Civil Rights Act of 1866

This law declared birthright citizenship and basic civil rights. It directly overturned Dred Scott v. Sandford. Johnson vetoed it, and Congress overrode him. That showed Congress was taking control.

Reconstruction Amendments

AmendmentWhat it did
13thAbolished slavery except as punishment for crime
14thBirthright citizenship, due process, equal protection, penalties for denying male suffrage, barred some ex-Confederates from office
15thBanned denial of voting rights based on race, color, or previous condition of servitude

The women’s rights movement grew stronger but split here. Elizabeth Cady Stanton and Susan B. Anthony formed the National Woman Suffrage Association. Lucy Stone and Henry Blackwell formed the American Woman Suffrage Association.

Congressional Reconstruction in Action

Congressional Republicans ranged from moderates to Radicals like Thaddeus Stevens and Charles Sumner. They wanted stronger federal protection.

The Reconstruction Acts of 1867 divided the former Confederacy except Tennessee into five military districts. States had to register Black male voters, hold conventions, write new constitutions, ratify the 14th Amendment, and win congressional approval.

Johnson fought back and was impeached in 1868 over Edwin Stanton and the Tenure of Office Act. The House impeached him, but the Senate acquitted him by one vote. Congress still dominated Reconstruction.

Republican governments in the South rested on a coalition of:

  • Freedmen
  • Scalawags who were white southern Republicans
  • Carpetbaggers who were northern migrants

African Americans voted, served on juries, and held office. Named examples you should know together:

  • Hiram Revels: first Black U.S. senator
  • Blanche K. Bruce: first Black senator to serve a full term
  • Robert Smalls: formerly enslaved war hero turned congressman

Their governments built public schools, rebuilt infrastructure, expanded public services, pushed fairer taxes, and protected civil rights. This was the South’s first real experiment in interracial democracy.

Resistance, Enforcement, and Why Reconstruction Was Limited

White southern resistance aimed to destroy Black political power and Republican rule.

Major examples:

  • Memphis Riot 1866
  • New Orleans Riot 1866
  • Ku Klux Klan, founded in 1866

Congress answered with the Enforcement Acts of 1870 and 1871, including the Ku Klux Klan Act. These made voter intimidation and civil-rights violations federal crimes. President Grant used force in places like South Carolina.

This worked for a while, but Reconstruction had weak foundations:

  • no broad land redistribution
  • continued economic dependence
  • persistent white violence
  • weakening northern commitment

The final judgment is the one APUSH loves. Reconstruction won huge legal and constitutional gains, but many stayed only partly secure because enforcement and northern resolve did not last.

Key Takeaways

Reconstruction was always about both race and power, meaning rights for freedpeople and control over reunion.
The 14th Amendment is the biggest long-term constitutional change because it nationalized citizenship and expanded federal protection of rights.
Black Codes mattered because they proved slavery was gone legally but white control was still being rebuilt in new forms.
Congressional Reconstruction created real Black political participation in the South, even though it was temporary.
Reconstruction did not fail because nothing changed. It failed because major changes were not protected long enough to last.
