7. Southern economy depended upon this

Please help me with this!

The phrase "Southern economy depended upon this" is incomplete and unclear. However, I can provide you with some general information about the Southern economy in the United States, which might help you understand what it depended upon.

Prior to the American Civil War, the Southern economy was largely dependent on agriculture, specifically the cultivation and production of cotton, tobacco, rice, and sugar cane. These agricultural products were mainly grown on plantations, which were large estates owned by wealthy individuals or families. Slavery played a significant role in the Southern economy, as enslaved individuals were used as laborers on these plantations.

Cotton was the most important cash crop in the South, and it fueled the region's economic growth. The invention of the cotton gin by Eli Whitney in 1793 made cotton production more efficient, leading to a significant increase in the demand for enslaved labor. This led to the expansion of slavery in the South and the growth of the plantation system.

It is important to note that this description provides a general overview of the historical context. If you have a specific question or topic related to the Southern economy, please provide more details, and I would be happy to assist you further.
