The Reconstruction Era (1865-1877) marked a pivotal period in American history following the Civil War. It aimed to reunite the nation, rebuild the South, and integrate newly freed slaves into society. This era saw significant political, economic, and social changes. Key events included the passage of the Reconstruction Amendments, the establishment of the Freedmen's Bureau, and the rise of the Ku Klux Klan. The era ended with the Compromise of 1877, leading to the withdrawal of federal troops from the South and the rise of Jim Crow laws.
