What factors were involved in the growth of southern slavery?

The growth of southern slavery was primarily driven by the expansion of cash crops, particularly cotton, which created a high demand for labor. The invention of the cotton gin in 1793 significantly increased cotton production efficiency, further entrenching the need for enslaved workers. Additionally, economic factors, such as the profitability of slavery and the demand for agricultural goods in both domestic and international markets, reinforced the institution. Social and political factors, including state laws supporting slavery and the cultural norms of the time, also played a crucial role in its expansion.
