How did the Civil War bring temporary and lasting changes to American society?

It freed all of the black men and ended the issue over slavery, but the South's economy was destroyed while the North's economy boomed.

Explanation:

The first three postwar amendments accomplished the most radical and rapid social and political change in American history: the abolition of slavery (13th) and the granting of equal citizenship (14th) and voting rights (15th) to former slaves, all within a period of five years. Some long-term effects that occurred after the Civil War were the abolishment of slavery, the formation of blacks' rights, industrialization and new innovations. The Northern states were not reliant on plantations and farms; instead they were reliant on industry.

in the 1800s, locomotives powered by steam made transportation faster and cheaper. the resulting rapid growth of railroads led to the connection of the atlantic and pacific railroad in oklahoma city in 1897.

in the last years of the century, the improvement of steam-based engines the expansion and growth of railroads. this growth increased when the companies started to build and expand, such as the atlantic and pacific railroad, which connected new mexico with california, and missouri with oklahoma. many of these new networks were built in oklahoma, and these changes transportation henceforward.
