The correct answer is the Mexican American War
David Wilmot was a Congressman from the state of Pennsylvania who wanted to ban slavery from exisiting in the new territories that the US received after the Mexican American War. This includes modern day California, Arizona, New Mexico, Utah, Colorado, etc.
Wilmot's idea was met with fierece opposition from Southern politicians. This is due to the fact that this would result in a significant increase in power for anti-slave states in Congress. Southerners feared that if Northern politicians gained too much power in Congress, they would outlaw the institution of slavery all over the United States. This fierece opposition is one of the reasons why the Wilmot Proviso is never actually used.
With the age of enlightenment, people started educating themselves more so naturally there were many more doctors that were educated people. The practice of having spiritual people to heal you with pseudomedicine started going down. People started discovering things that helped medicine develop. Women played a part because they started working in the medical field like nurses, they would deliver children, or even learn how to help people themselves.
