How did the south states get back into to the union after the civil war?

After the Civil War, Southern states were readmitted to the Union through a process called Reconstruction, which involved several key steps. The U.S. Congress passed the Reconstruction Acts in 1867, dividing the South into military districts governed by Union generals. Southern states had to draft new constitutions that guaranteed civil rights for freed slaves and ratify the 14th Amendment to ensure their readmission. This process varied by state, and some faced challenges, including resistance from local populations and ongoing violence.
