IB History Topic Reconstruction Revision Notes (HL)

Presidential Reconstruction (1865–1867)

After Lincoln’s assassination in April 1865, President Andrew Johnson implemented a lenient plan that allowed Southern states to rejoin the Union quickly if they ratified the 13th Amendment (abolishing slavery) and swore loyalty to the U.S. government.
Johnson offered pardons to most Confederate leaders and landowners, allowing prewar elites to regain political power and reestablish white-dominated state governments.
Many Southern legislatures then passed Black Codes, restrictive laws that limited the freedom and rights of freed African Americans, effectively reimposing slavery in all but name.

Andrew Johnson and the Struggles of Reconstruction (1865–1869)

Presidential Reconstruction

Johnson’s plan for Reconstruction (1865–1867) offered lenient terms to former Confederate states, allowing them to rejoin the Union quickly with minimal conditions.
He pardoned many ex-Confederates and allowed Southern states to form new governments that soon passed Black Codes, laws restricting the rights and mobility of freed African Americans.
His leniency angered Radical Republicans in Congress, who sought to guarantee civil and political rights for freedmen.

Conflict with Congress

Congress responded with the Civil Rights Act (1866) and the 14th Amendment, granting citizenship and equal protection under the law.
Johnson vetoed these measures, but Congress overrode his vetoes.
Tensions culminated in Johnson’s impeachment (1868) after he violated the Tenure of Office Act by removing Secretary of War Edwin Stanton without Senate approval.
He narrowly avoided removal from office by one Senate vote.

Legacy

Johnson’s presidency is often viewed as a failure of leadership during a critical turning point in U.S. history.
His opposition to Radical Reconstruction delayed progress on racial equality and left the South dominated by former Confederates.
Despite surviving impeachment, his weak presidency paved the way for Ulysses S. Grant’s election (1868) and a more assertive federal Reconstruction policy.

Definition

Black Codes

Laws passed by Southern states after the Civil War to restrict the freedom and labor rights of African Americans, especially their labour choices, movement, and legal rights.

Definition

Impeachment

The process by which a legislative body formally charges a government official with misconduct; Johnson was the first U.S. president impeached.

Congressional (Radical) Reconstruction (1867–1877)

Outraged by Johnson’s leniency, Radical Republicans in Congress took control of Reconstruction. Their goal was to reshape Southern society and guarantee civil rights for freedpeople.
The Reconstruction Acts of 1867 divided the South into five military districts under federal control until new state constitutions were written and approved by Congress.
Congress passed the 14th Amendment (granting citizenship and equal protection) and the 15th Amendment (granting Black men the right to vote), extending constitutional rights to African Americans.
Under federal supervision, African Americans began voting and holding public office, with over 600 elected to state legislatures and 16 to Congress during Reconstruction.

Methods of Southern Resistance

Many white Southerners resisted these changes through violence and intimidation. Groups like the Ku Klux Klan (founded in 1866) used terror to suppress Black political participation and restore white supremacy.
Economic coercion, through sharecropping contracts and debt peonage, kept freed people tied to plantations, maintaining dependency on white landowners.
Political resistance included the rise of Redeemer governments in the South, which gradually regained control and rolled back Reconstruction policies by the mid-1870s.

Economic and Social Outcomes

The postwar Southern economy remained largely agricultural, dependent on sharecropping and tenant farming, systems that trapped Black and poor white farmers in cycles of debt.
Despite federal programs like the Freedmen’s Bureau (1865), which provided food, education, and legal aid to freedpeople, economic progress was limited by lack of land reform and ongoing discrimination.
Socially, Reconstruction brought major achievements in Black education and institution-building—thousands of schools, churches, and community organizations were established across the South.

Case study

The Freedmen’s Bureau (1865–1872)

Established by Congress in March 1865, the Freedmen’s Bureau aimed to assist formerly enslaved people and poor whites in the postwar South.
It provided food, shelter, medical care, education, and legal aid, representing one of the first large-scale federal social programs.
The Bureau helped establish over 4,000 schools and several universities, including Howard University and Fisk University, dramatically increasing literacy rates among freedpeople.
Bureau courts helped settle labor disputes and defended freedpeople against exploitation, though its limited resources and local opposition hindered enforcement.
Southern elites and white supremacist groups saw the Bureau as a threat to their power, often attacking its agents and institutions.
Congress ended funding in 1872, under pressure from President Grant and northern voters tired of Reconstruction, leaving many freedpeople without continued federal protection.
Despite its short lifespan, the Bureau symbolized both the possibilities and limits of Reconstruction, achieving humanitarian progress but failing to ensure lasting equality.

Political Successes and Failures

Reconstruction marked the first experiment in interracial democracy in U.S. history, but its success was short-lived. By the Compromise of 1877, federal troops were withdrawn from the South, effectively ending Reconstruction.
Southern states quickly introduced Jim Crow laws and voting restrictions (poll taxes, literacy tests), dismantling the political gains of African Americans and enforcing racial segregation for nearly a century.
The period left a lasting legacy of constitutional reform (13th–15th Amendments) but also exposed the deep racial, regional, and political divides that would persist well into the 20th century.

Common Mistake

Oversimplifying Reconstruction as a failure : students often ignore its constitutional and educational achievements.
Neglecting the difference between Presidential and Congressional plans, which reflected competing visions for national reunification.
Focusing only on race, rather than also addressing the political, economic, and regional dimensions of Reconstruction’s challenges.

Exam technique

Contrast approaches : Clearly distinguish Presidential leniency from Congressional reform and explain how power shifted between them.
Analyze continuity and change : Show how Southern resistance undermined progress and led to new systems of racial control.
Support arguments with key legislation and examples :Mention the Freedmen’s Bureau, Black Codes, Reconstruction Acts, and the 13th–15th Amendments.
