During the Reconstruction, the Freedmen Bureau was made to help the newly Freemen find jobs, shelter, clothing, and food.
The Reconstruction area was a failure as it didn't really do a lot of things to help the newly freedmen. Yes, it freed them, but during the era, the government also didn't do anything to stop the Black Codes, the Jim Crow laws, and the KKK clan.
Yes, they would have been different. Lincoln's plan for Reconstruction was a very lenient plan that didn't punish the Southern states and just asked them to include the 13th amendment (freedom to all slaves) in their constitutions, and nothing else. His plan was basically to get America united as fast as possible. Though we're all sad that he got assassinated because he was a great president whereas his vice-president was not, the Radical Republicans' plan was much better. It punished the southern states and it also forced them to add the 13th (freedom for all slaves), 14th (citizenship to everyone who was born on American soil), and the 15th (voting rights to all men) amendments.
