To what extent did constitutional and social developments spark change in the United States between 1860 and 1877?

Answer 1

The emancipation proclamation was signed by Abraham Lincoln in 1863. This was the notice that all slaves were free. However, this notice did not reach most slaves, so they continue to think they were enslaved. Slavery ended in 1865. Soon followed by the 14th amendment in 1868.
