What steps did the south have to take to be readmitted back into the union after the war? simple answer plaese!

Lincoln's Plan for Reconstruction 

Abraham Lincoln wanted to be lenient to the South and make it easy for southern states to rejoin the Union. He said that any southerner who took an oath to the Union would be given a pardon. He also said that if 10% of the voters in a state supported the Union, then a state could be readmitted. Under Lincoln's plan, any state that was readmitted must make slavery illegal as part of their constitution. 

Rejoining the Union 

New governments were formed in the South starting in 1865. The first state to be readmitted to the Union was Tennessee in 1866. The last state was Georgia in 1870. As part of being readmitted to the Union, states had to ratify the new amendments to the Constitution. 

Hope this helps!
