Answer:
After independence, distinct regional identities began to develop in the United States between the north and south of the country.
In the north, a liberal and open society began to develop, with an economy based on manufacturing and industrial production, and where religious concepts, although present, did not greatly determine the daily life of the inhabitants. In this region, wealth is mediated not so much by land extensions, but by the possession of goods or even the ownership of means of production.
In the south, on the other hand, society took a much more conservative, religious, and above all racist course. In it, the white man had an absolute superiority of rights over the blacks. Furthermore, there was a rural society, where the main production was agricultural and livestock in nature, and where wealth was mediated by the extensions of land that each landowner owned.
These social differences soon became political, with the Republican Party representing the north and the Democrats representing the south; and it was these differences that led to the conflict that led to the Civil War.
