Answer:
Some Northerners believed slavery was morally wrong, while Southerners believed slavery was an essential part of their lives.
Explanation:
From colonial times until the end of the Civil War, slavery was one of the most burning and divisive issues in American society.
There were two very different positions: the abolitionists, who wanted the complete eradication of slavery and the integration of African-Americans into society on an equal basis; and slavers, who defended the existence of slavery based on the "inherent inequality" between whites and blacks.
Abolitionists were concentrated in the north of the country, where more progressive ideas were defended and production was mainly manufacturing and industrial, so there was no need for slave labor.
The slavers, on the other hand, were located mainly in the south, where production was essentially agricultural and livestock, so a large amount of labor was needed to exploit the enormous areas of land.
