The Reconstruction period after the Civil War ended in 1877. There were attempts to solve the inequalities of slavery and soften its social, economic and political impact, and to address the complex issues of readmission of the states that had seceded from the Union.

Real legal equality of black Americans would only be achieved in the 1960s.
