How did the nation reunite after Civil War?

The United States reunited after the Civil War through a process known as Reconstruction, which aimed to rebuild the South and integrate formerly enslaved people into society. Key measures included the passage of the Reconstruction Amendments, which granted citizenship and voting rights to African Americans, and the establishment of military districts to oversee the South's reintegration. The Compromise of 1877 effectively ended Reconstruction, leading to the withdrawal of federal troops and the return of white Democratic control in Southern states. This period laid the groundwork for both progress and ongoing racial tensions in the nation.
