Harriet Tubman (born Araminta Ross, c. March 1822 – March 10, 1913) was an American abolitionist and political activist. Born into slavery, Tubman escaped and subsequently made some 13 missions to rescue approximately 70 enslaved people, including family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad. During the American Civil War, she served as an armed scout and spy for the Union Army. In her later years, Tubman was an activist in the struggle for women's suffrage.
Born a slave in Dorchester County, Maryland, Tubman was beaten and whipped by her various masters as a child. Early in life, she suffered a traumatic head wound when an irate slave owner threw a heavy metal weight intending to hit another slave, but hitting her instead. The injury caused dizziness, pain, and spells of hypersomnia, which occurred throughout her life. After her injury, Tubman began experiencing strange visions and vivid dreams, which she ascribed to premonitions from God. These experiences, combined with her Methodist upbringing, led her to become devoutly religious.
In 1849, Tubman escaped to Philadelphia, only to return to Maryland to rescue her family soon after. Slowly, one group at a time, she brought relatives with her out of the state, and eventually guided dozens of other slaves to freedom. Traveling by night and in extreme secrecy, Tubman (or "Moses", as she was called) "never lost a passenger". After the Fugitive Slave Act of 1850 was passed, she helped guide fugitives farther north into British North America (Canada), and helped newly freed slaves find work. Tubman met John Brown in 1858, and helped him plan and recruit supporters for his 1859 raid on Harpers Ferry.
