The Underground Railroad was ironically neither underground nor a railroad, but rather a network of secret routes and safe houses used by 19th-century black slaves in the United States to escape to free states and Canada. The secret routes and safe houses were tagged by a lantern on a post in front of the house (or another sign) so the slave would know that it was safe to go there. Those who most actively assisted slaves to escape using the Underground Railroad were members of the free black community, including former slaves such as Harriet Tubman, Northern Abolitionists, philanthropists, and church leaders. The famous Underground Railroad has been said to have helped 30,000 slaves escape to freedom.
