The Reconstruction Era was a period in American history from 1865 to 1877, following the Civil War. Its main goal was to rebuild the Southern states and integrate formerly enslaved people into society. This era saw significant changes, including the passage of the 13th, 14th, and 15th Amendments, which aimed to abolish slavery, grant citizenship, and secure voting rights for African Americans. During Reconstruction, the federal government implemented various policies to promote civil rights and economic recovery in the South. However, resistance from groups like the Ku Klux Klan and the establishment of Black Codes hindered progress. Ultimately, Reconstruction ended with the Compromise of 1877, leading to the withdrawal of federal troops from the South.
