What year was the under ground rail road built?

Answer 1

The Underground Railroad was not a physical railroad but rather a network of secret routes and safe houses used by enslaved African Americans to escape to free states and Canada. It operated primarily during the 19th century, particularly from the 1810s to the 1860s, leading up to the Civil War. Key figures like Harriet Tubman played significant roles in its operation, but there was no specific year for its "construction" as it was an informal system rather than a built structure.
