Harriet Tubman was an American abolitionist and political activist. Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry. During the Civil War, she served as an armed scout and spy for the United States Army. In her later years, Tubman was an activist in the struggle for women's suffrage.
