How did the U. S. West change during the course of the Civil War? What is one effect of that change?

The Civil War encouraged people from the East to move towards the West.

Explanation:

Various groups of people moved to the West after the Civil War were the Southerners, African Americans along with Mormons, and Protestants when the government issued an Act called the Homestead Act of 1862. Under this Act, land in the West was opened for thousands of Americans to settle there. People started to move to the West because of population growth in the eastern states. Fertile land at a lower price in the West drove the white Americans to build ranches and farms.
