Answer:
Step-by-step explanation:
As the industry expanded, the northern region became the leading industrial region in the United States. This helped lead to the formation of unions and the first strikes for higher wages. These industries compelled railroads, which led to the development of railroads. The Southern States remained primarily agricultural, but the expansion of Northern industries led to an increase in demand for cotton, which helped fuel the growth of slavery. Many African Americans began to flee to the Northern States in search of work and freedom. The majority of railroads were destroyed during the war and had to be reconstructed. The West was a new region at the time, and there was debate over whether slavery should be permitted in this new territory. Despite this, the region had a lot of room for development, which allowed for immigration, particularly Chinese immigrants, who mostly worked on the Railway System. There was a different social settlement in the Midwest, there was a development of labor unions but most of them were created by farmers who were active in politics and aimed to make social reforms, this region also had a large number of immigrants to work in low-wage jobs. However, with the growth of the industry in the North and cotton plantations in the South, the Midwest became a major hub for the shipping and transportation of goods, assisting cities to grow and develop.
