The term Reconstruction Era, in the context of the history of the United States, has two senses: the first covers the complete history of the entire country from 1865 to 1877 following the American Civil War (1861 to 1865); the second sense focuses on the attempted transformation of the Southern United States from 1863 to 1877, as directed by Congress, with the reconstruction of state and society. With the three Reconstruction Amendments, the era saw the first amendments to the U.S. Constitution in decades. 

Three visions of Civil War memory appeared during Reconstruction: the reconciliationist vision, which was rooted in coping with the death and devastation the war had brought; the white supremacist vision, which included terror and violence; and the emancipationist vision, which sought full freedom, citizenship and Constitutional equality for African Americans. 

Presidents Abraham Lincoln and Andrew Johnson both took moderate positions designed to bring the South back into the union as quickly as possible, while Radical Republicans in Congress sought stronger measures to upgrade the rights of African Americans, including the Fourteenth Amendment to the United States Constitution, while curtailing the rights of former Confederates, such as through the provisions of the Wade–Davis Bill. Johnson followed a lenient policy toward ex-Confederates. Lincoln's last speeches show that he was leaning toward supporting the enfranchisement of all freedmen, whereas Johnson was opposed to this.
