Reconstruction era
The Reconstruction era, was a period in American history following the American Civil War (1861–1865); it lasted from 1865 to 1877 and marked a significant chapter in the history of civil rights in the United States. Reconstruction, as directed by Congress, abolished slavery and ended the remnants of Confederate secession in the Southern states; it presented the newly freed slaves (freedmen; Black people) as citizens with (ostensibly) the same civil rights as those of other citizens, and which rights were guaranteed by three new constitutional amendments, the 13th, 14th, and 15th Amendments. "Reconstruction" also refers to the attempt by Congress to transform the 11 former Confederate states; and it refers to the role of the Union states in that transformation.
