Answer: It is estimated that possibly as many as 100,000 slaves escaped via the Underground Railroad from 1800 to 1850.
Explanation:
The Underground Railroad was a route to help the enslaved escape. It was run by many different people including some that were previously enslaved and some from the North.
They used "train" terms and songs to share information to help this escape remain secret. Those escaping were "passengers," places to meet up were "stations," the "conductor" helped move people, etc.
