1866
The Ku Klux Klan was organized in Pulaski, Tennessee in late 1865 or early 1866 by former Confederate officers, including Nathan Bedford Forrest as Grand Wizard. By 1868 the Klan operated across the South, using murder, arson, and flogging to suppress Black voting, terrorize Republican officials, and destroy Black churches and schools. Congress estimated thousands were killed by 1871.
By 1870 the Freedmen's Bureau had helped establish over 4,000 schools serving roughly 247,000 students across the South, staffed by approximately 9,300 teachers. It partnered with Northern missionary societies including the American Missionary Association. The Bureau also created or supported Fisk, Howard, Hampton, and other institutions that became historically Black colleges. Formerly enslaved people organized self-taxation to build schoolhouses.

- 1866Convict Leasing System Begins Re-Enslaving Black Southerners
Southern states began leasing Black prisoners to private companies, railroad contractors, and planters under the Thirteenth Amendment's exception for criminal punishment. Black men arrested for trivial offenses — vagrancy, loitering, failing to show proof of a labor contract — were sentenced to months or years of unpaid forced labor in conditions often worse than antebellum slavery, with no incentive for employers to preserve workers' lives. The system persisted in some states until the 1940s.
- January 1866President Johnson Vetoes Reconstruction Legislation, Enabling Southern Resistance
President Andrew Johnson vetoed the Freedmen's Bureau extension bill in February 1866 and the Civil Rights Act in April, arguing that Black people were not entitled to federal protection and that Southern states should determine their own labor and race relations. Johnson's vetoes were overridden but his presidential pardons of Confederate leaders, restoration of their political rights, and return of confiscated land to former slaveholders effectively dismantled early Reconstruction policy. Johnson's active collusion with former Confederates was central to the failure to secure freedpeople's rights.
- 1866Ku Klux Klan Expands as Paramilitary Terrorist Force
Founded in Pulaski, Tennessee in late 1865, the Ku Klux Klan expanded dramatically under former Confederate General Nathan Bedford Forrest as Grand Wizard from 1867-1869. The Klan used night raids, whippings, and murder to destroy Republican Party infrastructure, suppress Black voting, and drive Black people from land they had acquired. Targets included Black officeholders, teachers in Freedmen's Bureau schools, and white Republican allies.
- 1866Sharecropping System Emerges to Replace Slavery
After emancipation and the failure of land redistribution, a sharecropping system rapidly consolidated across the South by 1866. Freedpeople farmed white-owned land for a share of the crop — typically one-third to one-half — but planters controlled the accounting, supply stores, and contracts. Debt peonage trapped families in cycles of obligation functionally indistinguishable from servitude.
- March 27, 1866Andrew Johnson Vetoes Civil Rights Act of 1866
President Johnson vetoed the Civil Rights Act of 1866, which would have granted citizenship to freedpeople. His veto message argued Black Americans were not ready for citizenship and that Congress had no power to confer it. Congress overrode the veto — the first major override of a presidential veto in American history — but Johnson's obstruction emboldened Southern resistance.
- 1866Black Communities Organize Armed Self-Defense Across South
Black veterans organized armed self-defense units throughout Reconstruction. In SC, legally constituted Black militia companies provided some protection until Redeemer governments disarmed them. At Colfax and elsewhere, Black men armed themselves to defend election results. Self-defense was a persistent strategy against Klan and White League terror, even when federal protection was absent or delayed.
- 1866Thaddeus Stevens Leads Congress's Radical Reconstruction Push
Rep. Thaddeus Stevens of PA floor-managed the 14th Amendment, the Reconstruction Acts, and multiple Freedmen's Bureau bills over Johnson's vetoes. He consistently argued land redistribution was necessary for meaningful freedom and proposed confiscating Confederate estates for 40-acre homesteads — a proposal that failed. He died in August 1868 and was buried in a Black cemetery to protest segregation.

By 1870 the Freedmen's Bureau had helped establish over 4,000 schools serving roughly 247,000 students across the South, staffed by approximately 9,300 teachers.

- 1866Black Communities Organize Armed Self-Defense Across South
Black veterans and community members organized armed self-defense units throughout Reconstruction. In South Carolina, legally constituted Black militia companies provided some protection for Republican governance until Redeemer governments disarmed them. In Colfax and elsewhere, Black men armed themselves to defend election results. Black response to the Hamburg attack included organized armed defense. Self-defense was a persistent strategy against Klan and White League terror even when federal
- 1866Thaddeus Stevens Champions Radical Reconstruction in Congress
Representative Thaddeus Stevens of Pennsylvania led the House fight for Radical Reconstruction, floor-managing the Fourteenth Amendment, the Reconstruction Acts, and repeated Freedmen's Bureau renewal bills over Johnson's vetoes. Stevens consistently argued that land redistribution was necessary for meaningful freedom; he proposed confiscating Confederate estates and distributing 40-acre homesteads to freedpeople, but the proposal failed. He died in August 1868, requesting burial in a Black ceme
- 1866Fraudulent Labor Contracts Trap Freedpeople in Debt Peonage
Throughout Reconstruction, freedpeople entering labor contracts with planters faced systematic fraud. Planters charged for food, tools, and housing at inflated rates, ensuring workers ended each year deeper in debt. Freedmen's Bureau agents mediated thousands of disputes but were too few to cover the South systematically. After the Bureau closed in 1872, Black workers had no recourse against fraudulent accounting. State laws made leaving a farm while in debt a criminal offense, creating debt peo

Freedmen's Bureau agents mediated thousands of disputes but were too few to cover the South. After the Bureau closed in 1872, Black workers had no recourse. State laws made leaving a farm while in debt a criminal offense, creating debt peonage effectively identical to slavery.

Johnson vetoed the Freedmen's Bureau renewal bill on Feb. 19, 1866, arguing it was unconstitutional. The Senate initially failed to override.

The Senate initially failed to override by two votes. Johnson's veto began a sustained battle with the Radical Republican Congress; a second Bureau bill passed over his veto in July 1866 with Thaddeus Stevens leading the floor fight in the House.
