embarraseed and small
they felt happy because they won the civil war
Because the Southerners had to pass Richmond and burn the crops the Union could get.
Abraham Lincoln, because he was on south side
At the end of the US Civil War there were no slaves, they had all been freed during the war and by the fact that the South lost the war. Thus your question makes no sense and can not be answered.
The end didn't lead to segregation, the racism of Southerners did. The North winning the war did nothing to change Southerners views on Blacks. So they formed the KKK, terrorized anyone trying to help Blacks, and did all they could to keep Blacks at the bottom of Southern society and unequal. Segregation was simply a logical end to these racist beliefs.
Slaves.
The proximate cause was the election of Abraham Lincoln in November 1860; white Southerners feared, correctly, that Lincoln would work to end slavery in the US. Slavery was the principal cause of the US Civil War; states' rights were a secondary issue.
End of Civil War.
Northerners and southerners became more angry with each other.
The Civil War led to the end of Slavery.
It depend which civil war you are referring to.
Many slaves had served in the Civil War. There were about 4 million slaves under bondage by the end of the Civil War.
