The+Underground+Railroad

The Underground Railroad was a series of secret routes and safe houses used by 1800 Black slaves in the United States to escape to free states and Canada with the aid of abolitionists who were sympathetic to their cause. Other various routes led to Mexico or overseas. The Underground Railroad was at its height between 1810 and 1850, with over 30,000 people escaping enslavement though US Census figures only account for 6,000.
