Presidential Reconstruction
In 1865 President Andrew Johnson implemented a plan of Reconstruction that gave the white South a free hand in regulating the transition from slavery to freedom and offered no role to blacks in the politics of the South. The conduct of the governments he established turned many Northerners against the president's policies.
The end of the Civil War found the nation without a settled Reconstruction policy.
In May 1865, President Andrew Johnson offered a pardon to all white Southerners except Confederate leaders and wealthy planters (although most of these later received individual pardons), and authorized them to create new governments.
The buffalo soldiers were expected to be the weaker lot - not as good as the white soldiers, most people who were in the army did not have much hope for them.They did not get as good quality guns,they had old uniform given out to them and got second priority after the white soldiers-I.e if there wasn't enough tents for both lots the white soldiers would come first so they would get the tents while the buffalo soldiers would have to sleep on the ground.Racial Abuse was experienced continuously, at the start of the buffalo soldiers time , slavery had just been abolished so it was difficult for black soldiers to be seen equal and free to the white soldiers who were used to treating them horribly, and saw the black soldiers as unable and useless.The black and white soldiers were also segregated into separate lots.
Now that is not the case, racism is not tolerated even though unfortunately it still happens in some cases.
