There was an increase in the number of enslaved people due to the invention of the cotton gin, which made plantation agriculture more profitable.

Explanation:

The cotton gin, invented by Eli Whitney in 1793, was the invention that allowed the Southern United States to become the cotton powerhouse that it was in the 1800s. This small machine allowed to mechanically separate the cotton fibers from the seeds that were attached, quickly and repetitively, greatly reducing the separation time that a human could take.

Consequently, cotton plantations became the most profitable activity for the agricultural states and territories in the South, because they could produce in a much shorter time a greater quantity of cotton fibers. Thus, producers began to multiply their production by dozens, requiring greater amounts of labor. In this way, they began to acquire increasing numbers of slaves from Africa.
