Answer: The Underground Railroad was a network of secret routes and safe houses established in the United States during the early to the mid-19th century. It was used primarily by enslaved African-Americans to escape into free states and Canada. The plan was supported by abolitionists and others sympathetic to the cause of the escapees. In addition to the enslaved who risked escape, those who helped them are collectively referred to as the "Underground Railroad". Many other routes led to Mexico, where slavery was legal.
Harriet Tubman was "(born in 1820, Dorchester County, Maryland, US-died March 10, 1913, Auburn, New York)", "American bondwoman who escaped slavery in the South in order to become an abolitionist before the American Civil War". She led dozens of enslaved people to freedom in the North by using the Underground Railroad, an elaborate secret network of safe houses.
Harriet Tubman was an escaped slave who became a "conductor" on the Underground Railroad and led enslaved people to freedom before the Civil War, all while carrying a bounty on her head. She was also a nurse, a spy for the Union, and a supporter of the women's suffrage movement.
