The correct answer is 1) The plans for restoring Southern states to the Union.
After the Civil War, the era of Reconstruction began. One of the biggest issues on the table was how were the former Confederate States going to rejoin the Union. There was two very different sides to this story.
Radical Republicans wanted to punish the former Confederate States for causing the Civil War. They wanted harsh financial and political punishments. However, Andrew Johnson did not want to harshly punish the former Confederate States. Rather, he wanted them to rejoin the United States as soon as possible.
