What 12 year period is usually considered to be the years of reconstruction?

The period of Reconstruction in the United States is typically considered to span from 1865 to 1877. This era followed the Civil War and focused on rebuilding the South, integrating formerly enslaved individuals into society, and redefining the relationship between the states and the federal government. Reconstruction officially ended with the Compromise of 1877, which resolved the contested 1876 presidential election and led to the withdrawal of federal troops from the South.
