Final answer:
New Orleans was home to the largest slave market in the US, particularly significant during the domestic slave trade between 1820 and 1860. While the specific name for the largest sale of slaves is not given, the information highlights the importance of slave trade markets in Southern economic history.
Step-by-step explanation:
The name given to the largest sale of slaves in US history is not explicitly mentioned in the provided reference material. However, the references do demonstrate that New Orleans had the largest slave market in the United States and was a primary hub for the domestic slave trade. This trade was a significant part of the economy, especially between 1820 and 1860, when about 200,000 people were sold and relocated each decade. Moreover, massive numbers of enslaved people were transported from states like Virginia, Maryland, the Carolinas, and further afield to be sold for labor in places like the Mississippi Valley, making it one of the largest forced internal migrations in the United States.
An 1840 advertisement by a slave trader for the sale of slaves at an auction in New Orleans, Louisiana, is an example of the public nature of these sales and underscores the economic opportunities it provided for white men in various roles involved in the slave trade.
