Step-by-step explanation:
Lincoln's vision of the Union after the Civil War can be described as one of reunification and reconciliation. His goal was to bring the Southern states back into the fold and restore the Union. He proposed a plan known as the ten percent plan, which offered a general pardon to Southerners (except high-ranking Confederate leaders), required a percentage of the voting population to take an oath of allegiance, and called for the emancipation of enslaved people. Lincoln also oversaw the passage of the Thirteenth Amendment abolishing slavery. Although he did not live to see its ratification, his vision laid the foundation for the Reconstruction era.
