What did the former confederate states have to do in order to be readmitted to the union?

Former Confederate states had to meet specific requirements to be readmitted to the Union after the Civil War. They were required to draft new state constitutions that abolished slavery, ratify the 14th Amendment, which granted citizenship and equal protection under the law to former slaves, and hold elections to create new governments that were loyal to the Union. Additionally, some states faced military oversight and had to demonstrate compliance with Reconstruction policies before being formally readmitted.
