What was that period Following the Civil War known as?

The period following the Civil War in the United States is known as Reconstruction, which lasted from 1865 to 1877. It was a time focused on rebuilding the South, integrating formerly enslaved people into society, and addressing the political, social, and economic challenges that arose from the war. Reconstruction involved significant legislative changes, including the 13th, 14th, and 15th Amendments, aimed at ensuring civil rights and voting rights for African Americans. However, it faced considerable resistance and ultimately ended with the withdrawal of federal troops from the South, leading to the implementation of Jim Crow laws and widespread discrimination.
