What was the significance of the Civil War for the further development of the modernization process in the United States?

The civil war in the United States, generated by the contradictions between supporters and opponents of slavery, led to the victory of the capitalists. The northerners chose a progressive path of development. In their opinion, discrimination should be eliminated. The exploitation of people for their own needs was also considered inhumane. The war in the middle of the 19th century was the beginning of the US economic leap, as the victorious northerners began to develop capitalist relations, a market economy. As a result, the GDP has increased, and the living conditions of many people have improved significantly.
