During which years did most of the reconstruction occur?

Most of the Reconstruction era in the United States took place from 1865 to 1877. This period followed the Civil War and focused on rebuilding the South, integrating formerly enslaved people into society, and addressing the political, social, and economic challenges that arose. Key legislative measures were enacted during this time, including the 13th, 14th, and 15th Amendments. Reconstruction officially ended in 1877 with the withdrawal of federal troops from the South.
