The
Underground Railroad was not a
railroad per se but rather a network of clandestine routes, often informal and impromptu, by which
slaves were able to escape the
United States and reach freedom either in states that protected fugitive slaves, or in
Canada. The Underground Railroad consisted of secret safe houses and other facilities owned by anti-slavery sympathizers, and operated much like any other large-scale widespread
resistance movement with independent cells that only knew of a few of their neighbours. Escaped slaves would pass from one way station to another, making their way north step by step.
