Final answer:
Andrew Johnson tried to industrialize and reintegrate the states after the Civil War.
Step-by-step explanation:
After the Civil War, the person who tried to industrialize and reintegrate the states was Andrew Johnson. He became president after Abraham Lincoln and shared Lincoln's view that the executive branch should control Reconstruction. Johnson implemented a plan in 1865 for readmitting the southern states to the Union. However, his plan faced opposition from many Republicans in Congress who disagreed with his leniency towards the former Confederate states.
