The primary reason for less interest in abolition in the South was that the South relied on the labor of enslaved people. The Southern economy was heavily dependent on agriculture, particularly cotton production, which was reliant on slave labor. As a result, many people in the South were invested in maintaining the institution of slavery, both economically and socially. This created significant resistance to abolitionist movements and ideas.
The other options you provided are not accurate representations of the historical context:
- Many people in the South were aware of the abolitionist movement, even if they opposed it.
- The entire enslaved population had not freed themselves.
- There were indeed enslaved people in the South, and they constituted a large portion of the population.
So, the correct answer is that the South relied on the labor of enslaved people.
