There are a number of factors that could have influenced the future of slavery in a Confederate victory scenario. These include:
* Economic factors: The plantation economy of the antebellum South was heavily dependent on slave labor. Without slavery, plantation owners would have had to find other sources of labor, which could have been difficult and expensive.
* Political factors: The political dynamics of a Confederate States of America would have been very different from those of the United States. It is possible that a Confederate government could have been more resistant to abolitionist pressures than the U.S. government was.
* Social factors: The social attitudes of white Southerners towards slavery would have played a significant role in determining the future of the institution. It is possible that white Southerners would have remained committed to slavery even if it was no longer economically viable.
In the end, it is impossible to say for sure what would have happened to slavery if the South had won the Civil War. However, it is important to remember that slavery was a complex and multifaceted institution, and there is no simple answer to the question of what would have happened to it if the Confederacy had been successful.
