The Reconstruction Era was a period that followed the American Civil War. The main purpose was to bring the South back together and basically starting a whole new rebuilding process so it would be part of the Union again. The South had to ratify it's amendments to be readmitted by the US and split the South into five different bases. This lasted from 1865-1877,some feel that it was successful because slavery ended and some feel that it was a failure because racism is still a issue. During this time period certain acts have passed and laws have been set African Americans had freedom but it still didn't mean equality. President Lincoln was assassinated when the Reconstruction first took place later his spot had gotten replaced by President Johnson. Johnson was indeed a racist so of course he didn't want slaves being free. Grant was elected president after Andrew Johnson's term ended and the blacks were able to vote this time. African American's were getting more leeway in America they were able to attend schools, ride buses there were even black getting into the government. The KKK stopped many blacks from doing a lot of political business stopping many from voting by terrorizing them. Slavery was abolished and Reconstruction was coming to an end, Northerners left the South to deal with their own people because they were tired of fighting for them.
