What were some of the political and economic changes brought about by the war

The Civil War had a major impact on the United States politically, socially, and economically. The South was also changed culturally by the Civil War. The Civil War led to the slaves being freed. The former slaves received rights that they were previously denied.  We have to bear in mind that after the war a massive construction of railroads started in the USA and that brought huge economic changes.
