How did this invention help fuel the need for slavery?

The invention of the cotton gin in 1793 revolutionized cotton production by dramatically increasing the efficiency of processing cotton fibers. This led to a surge in cotton cultivation in the Southern United States, which became a vital cash crop for the economy. The increased demand for cotton fueled the need for more labor, resulting in the expansion of slavery as plantation owners sought to maximize their profits through an enslaved workforce. Consequently, the cotton gin inadvertently entrenched and expanded the institution of slavery in America.
