Final answer:
The most profound effect of the discontinuation of the Atlantic slave trade to the US was the transformation of the economic system, leading to the growth of other industries and contributing to the tensions between the Northern and Southern states.
Step-by-step explanation:
The discontinuation of the Atlantic slave trade to the US had a profound effect on the nation. One of the most significant impacts was the transformation of the economic system. Slavery had been a foundation of the American economy, particularly in the Southern states where agriculture, such as cotton and sugar production, heavily relied on enslaved labor.
With the end of the slave trade, there was a decrease in the supply of enslaved laborers, leading to a shift in the economic structure. Plantation owners and businesses had to find alternative sources of labor and adapt their methods of production.
This change ultimately fueled the growth of other industries like manufacturing and contributed to the rise of the Industrial Revolution in the United States. It also played a role in the increasing tensions between the Northern and Southern states, ultimately leading to the American Civil War.
